some scenarios the exposed URL in the backend service differs from the specified path in the Ingress rule. Without a rewrite any request will return 404.\nSet the annotation \nnginx.ingress.kubernetes.io/rewrite-target\n to the path expected by the service.\n\n\nIf the application contains relative links it is possible to add an additional annotation \nnginx.ingress.kubernetes.io/add-base-url\n that will prepend a \nbase\n tag\n in the header of the returned HTML from the backend.\n\n\nIf the scheme of \nbase\n tag\n need to be specific, set the annotation \nnginx.ingress.kubernetes.io/base-url-scheme\n to the scheme such as \nhttp\n and \nhttps\n.\n\n\nIf the Application Root is exposed in a different path and needs to be redirected, set the annotation \nnginx.ingress.kubernetes.io/app-root\n to redirect requests for \n/\n.\n\n\n\n\nExample\n\n\nPlease check the \nrewrite\n example.\n\n\n\n\nSession Affinity\n\u00b6\n\n\nThe annotation \nnginx.ingress.kubernetes.io/affinity\n enables and sets the affinity type in all Upstreams of an Ingress. This way, a request will always be directed to the same upstream server.\nThe only affinity type available for NGINX is \ncookie\n.\n\n\n\n\nExample\n\n\nPlease check the \naffinity\n example.\n\n\n\n\nCookie affinity\n\u00b6\n\n\nIf you use the \ncookie\n affinity type you can also specify the name of the cookie that will be used to route the requests with the annotation \nnginx.ingress.kubernetes.io/session-cookie-name\n. The default is to create a cookie named 'INGRESSCOOKIE'.\n\n\nIn case of NGINX the annotation \nnginx.ingress.kubernetes.io/session-cookie-hash\n defines which algorithm will be used to hash the used upstream. Default value is \nmd5\n and possible values are \nmd5\n, \nsha1\n and \nindex\n.\n\n\n\n\nAttention\n\n\nThe \nindex\n option is not an actual hash; an in-memory index is used instead, which has less overhead.\nHowever, with \nindex\n, matching against a changing upstream server list is inconsistent.\nSo, at reload, if upstream servers have changed, index values are not guaranteed to correspond to the same server as before!\n\nUse \nindex\n with caution\n and only if you need to!\n\n\n\n\nIn NGINX this feature is implemented by the third party module \nnginx-sticky-module-ng\n. The workflow used to define which upstream server will be used is explained \nhere\n\n\nAuthentication\n\u00b6\n\n\nIs possible to add authentication adding additional annotations in the Ingress rule. The source of the authentication is a secret that contains usernames and passwords inside the key \nauth\n.\n\n\nThe annotations are:\n\n\nnginx.ingress.kubernetes.io/auth-type: [basic|digest]\n\n\n\n\n\nIndicates the \nHTTP Authentication Type: Basic or Digest Access Authentication\n.\n\n\nnginx.ingress.kubernetes.io/auth-secret: secretName\n\n\n\n\n\nThe name of the Secret that contains the usernames and passwords which are granted access to the \npath\ns defined in the Ingress rules.\nThis annotation also accepts the alternative form \"namespace/secretName\", in which case the Secret lookup is performed in the referenced namespace instead of the Ingress namespace.\n\n\nnginx.ingress.kubernetes.io/auth-realm: \"realm string\"\n\n\n\n\n\n\n\nExample\n\n\nPlease check the \nauth\n example.\n\n\n\n\nCustom NGINX upstream checks\n\u00b6\n\n\nNGINX exposes some flags in the \nupstream configuration\n that enable the configuration of each server in the upstream. The Ingress controller allows custom \nmax_fails\n and \nfail_timeout\n parameters in a global context using \nupstream-max-fails\n and \nupstream-fail-timeout\n in the NGINX ConfigMap or in a particular Ingress rule. \nupstream-max-fails\n defaults to 0. This means NGINX will respect the container's \nreadinessProbe\n if it is defined. If there is no probe and no values for \nupstream-max-fails\n NGINX will continue to send traffic to the container.\n\n\n\n\nTip\n\n\nWith the default configuration NGINX will not health check your backends. Whenever the endpoints controller notices a readiness probe failure, that pod's IP will be removed from the list of endpoints. This will trigger the NGINX controller to also remove it from the upstreams.**\n\n\n\n\nTo use custom values in an Ingress rule define these annotations:\n\n\nnginx.ingress.kubernetes.io/upstream-max-fails\n: number of unsuccessful attempts to communicate with the server that should occur in the duration set by the \nupstream-fail-timeout\n parameter to consider the server unavailable.\n\n\nnginx.ingress.kubernetes.io/upstream-fail-timeout\n: time in seconds during which the specified number of unsuccessful attempts to communicate with the server should occur to consider the server unavailable. This is also the period of time the server will be considered unavailable.\n\n\nIn NGINX, backend server pools are called \"\nupstreams\n\". Each upstream contains the endpoints for a service. An upstream is created for each service that has Ingress rules defined.\n\n\n\n\nAttention\n\n\nAll Ingress rules using the same service will use the same upstream.\n\nOnly one of the Ingress rules should define annotations to configure the upstream servers.\n\n\n\n\n\n\nExample\n\n\nPlease check the \ncustom upstream check\n example.\n\n\n\n\nCustom NGINX upstream hashing\n\u00b6\n\n\nNGINX supports load balancing by client-server mapping based on \nconsistent hashing\n for a given key. The key can contain text, variables or any combination thereof. This feature allows for request stickiness other than client IP or cookies. The \nketama\n consistent hashing method will be used which ensures only a few keys would be remapped to different servers on upstream group changes.\n\n\nTo enable consistent hashing for a backend:\n\n\nnginx.ingress.kubernetes.io/upstream-hash-by\n: the nginx variable, text value or any combination thereof to use for consistent hashing. For example \nnginx.ingress.kubernetes.io/upstream-hash-by: \"$request_uri\"\n to consistently hash upstream requests by the current request URI.\n\n\nCustom NGINX load balancing\n\u00b6\n\n\nThis is similar to (https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/configmap.md#load-balance) but configures load balancing algorithm per ingress.\n\n\n\n\nNote that \nnginx.ingress.kubernetes.io/upstream-hash-by\n takes preference over this. If this and \nnginx.ingress.kubernetes.io/upstream-hash-by\n are not set then we fallback to using globally configured load balancing algorithm.\n\n\n\n\nCustom NGINX upstream vhost\n\u00b6\n\n\nThis configuration setting allows you to control the value for host in the following statement: \nproxy_set_header Host $host\n, which forms part of the location block. This is useful if you need to call the upstream server by something other than \n$host\n.\n\n\nClient Certificate Authentication\n\u00b6\n\n\nIt is possible to enable Client Certificate Authentication using additional annotations in Ingress Rule.\n\n\nThe annotations are:\n\n\n\n\nnginx.ingress.kubernetes.io/auth-tls-secret: secretName\n:\n The name of the Secret that contains the full Certificate Authority chain \nca.crt\n that is enabled to authenticate against this Ingress.\n This annotation also accepts the alternative form \"namespace/secretName\", in which case the Secret lookup is performed in the referenced namespace instead of the Ingress namespace.\n\n\nnginx.ingress.kubernetes.io/auth-tls-verify-depth\n:\n The validation depth between the provided client certificate and the Certification Authority chain.\n\n\nnginx.ingress.kubernetes.io/auth-tls-verify-client\n:\n Enables verification of client certificates.\n\n\nnginx.ingress.kubernetes.io/auth-tls-error-page\n:\n The URL/Page that user should be redirected in case of a Certificate Authentication Error\n\n\nnginx.ingress.kubernetes.io/auth-tls-pass-certificate-to-upstream\n:\n Indicates if the received certificates should be passed or not to the upstream server. By default this is disabled.\n\n\n\n\n\n\nExample\n\n\nPlease check the \nclient-certs\n example.\n\n\n\n\n\n\nAttention\n\n\nTLS with Client Authentication is \nnot\n possible in Cloudflare and might result in unexpected behavior.\n\n\nCloudflare only allows Authenticated Origin Pulls and is required to use their own certificate: \nhttps://blog.cloudflare.com/protecting-the-origin-with-tls-authenticated-origin-pulls/\n\n\nOnly Authenticated Origin Pulls are allowed and can be configured by following their tutorial: \nhttps://support.cloudflare.com/hc/en-us/articles/204494148-Setting-up-NGINX-to-use-TLS-Authenticated-Origin-Pulls\n\n\n\n\nConfiguration snippet\n\u00b6\n\n\nUsing this annotation you can add additional configuration to the NGINX location. For example:\n\n\nnginx.ingress.kubernetes.io/configuration-snippet\n:\n \n|\n\n \nmore_set_headers \"Request-Id: $req_id\";\n\n\n\n\n\n\nDefault Backend\n\u00b6\n\n\nThe ingress controller requires a \ndefault backend\n.\nThis service handles the response when the service in the Ingress rule does not have endpoints.\nThis is a global configuration for the ingress controller. In some cases could be required to return a custom content or format. In this scenario we can use the annotation \nnginx.ingress.kubernetes.io/default-backend: \n to specify a custom default backend.\n\n\nEnable CORS\n\u00b6\n\n\nTo enable Cross-Origin Resource Sharing (CORS) in an Ingress rule,\nadd the annotation \nnginx.ingress.kubernetes.io/enable-cors: \"true\"\n.\nThis will add a section in the server location enabling this functionality.\n\n\nCORS can be controlled with the following annotations:\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-methods\n\n controls which methods are accepted.\n This is a multi-valued field, separated by ',' and accepts only letters (upper and lower case).\n Example: \nnginx.ingress.kubernetes.io/cors-allow-methods: \"PUT, GET, POST, OPTIONS\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-headers\n\n controls which headers are accepted.\n This is a multi-valued field, separated by ',' and accepts letters, numbers, _ and -.\n Example: \nnginx.ingress.kubernetes.io/cors-allow-headers: \"X-Forwarded-For, X-app123-XPTO\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-origin\n\n controls what's the accepted Origin for CORS and defaults to '*'.\n This is a single field value, with the following format: \nhttp(s)://origin-site.com\n or \nhttp(s)://origin-site.com:port\n\n Example: \nnginx.ingress.kubernetes.io/cors-allow-origin: \"https://origin-site.com:4443\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-credentials\n\n controls if credentials can be passed during CORS operations.\n Example: \nnginx.ingress.kubernetes.io/cors-allow-credentials: \"true\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-max-age\n\n controls how long preflight requests can be cached.\n Example: \nnginx.ingress.kubernetes.io/cors-max-age: 600\n\n\n\n\n\n\n\n\nNote\n\n\nFor more information please see \nhttps://enable-cors.org\n\n\n\n\nServer Alias\n\u00b6\n\n\nTo add Server Aliases to an Ingress rule add the annotation \nnginx.ingress.kubernetes.io/server-alias: \"\"\n.\nThis will create a server with the same configuration, but a different \nserver_name\n as the provided host.\n\n\n\n\nNote\n\n\nA server-alias name cannot conflict with the hostname of an existing server. If it does the server-alias annotation will be ignored.\nIf a server-alias is created and later a new server with the same hostname is created,\nthe new server configuration will take place over the alias configuration.\n\n\n\n\nFor more information please see \nthe \nserver_name\n documentation\n.\n\n\nServer snippet\n\u00b6\n\n\nUsing the annotation \nnginx.ingress.kubernetes.io/server-snippet\n it is possible to add custom configuration in the server configuration block.\n\n\napiVersion\n:\n \nextensions/v1beta1\n\n\nkind\n:\n \nIngress\n\n\nmetadata\n:\n\n \nannotations\n:\n\n \nnginx.ingress.kubernetes.io/server-snippet\n:\n \n|\n\n\nset $agentflag 0;\n\n\n\nif ($http_user_agent ~* \"(Mobile)\" ){\n\n \nset $agentflag 1;\n\n\n}\n\n\n\nif ( $agentflag = 1 ) {\n\n \nreturn 301 https://m.example.com;\n\n\n}\n\n\n\n\n\n\n\n\nAttention\n\n\nThis annotation can be used only once per host.\n\n\n\n\nClient Body Buffer Size\n\u00b6\n\n\nSets buffer size for reading client request body per location. In case the request body is larger than the buffer,\nthe whole body or only its part is written to a temporary file. By default, buffer size is equal to two memory pages.\nThis is 8K on x86, other 32-bit platforms, and x86-64. It is usually 16K on other 64-bit platforms. This annotation is\napplied to each location provided in the ingress rule.\n\n\n\n\nNote\n\n\nThe annotation value must be given in a format understood by Nginx.\n\n\n\n\n\n\nExample\n\n\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: \"1000\"\n # 1000 bytes\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1k\n # 1 kilobyte\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1K\n # 1 kilobyte\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1m\n # 1 megabyte\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1M\n # 1 megabyte\n\n\n\n\n\n\nFor more information please see \nhttp://nginx.org\n\n\nExternal Authentication\n\u00b6\n\n\nTo use an existing service that provides authentication the Ingress rule can be annotated with \nnginx.ingress.kubernetes.io/auth-url\n to indicate the URL where the HTTP request should be sent.\n\n\nnginx.ingress.kubernetes.io/auth-url\n:\n \n\"URL\n \nto\n \nthe\n \nauthentication\n \nservice\"\n\n\n\n\n\n\nAdditionally it is possible to set:\n\n\n\n\nnginx.ingress.kubernetes.io/auth-method\n:\n \n\n to specify the HTTP method to use.\n\n\nnginx.ingress.kubernetes.io/auth-signin\n:\n \n\n to specify the location of the error page.\n\n\nnginx.ingress.kubernetes.io/auth-response-headers\n:\n \n\n to specify headers to pass to backend once authentication request completes.\n\n\nnginx.ingress.kubernetes.io/auth-request-redirect\n:\n \n\n to specify the X-Auth-Request-Redirect header value.\n\n\n\n\n\n\nExample\n\n\nPlease check the \nexternal-auth\n example.\n\n\n\n\nRate limiting\n\u00b6\n\n\nThese annotations define a limit on the connections that can be opened by a single client IP address.\nThis can be used to mitigate \nDDoS Attacks\n.\n\n\n\n\nnginx.ingress.kubernetes.io/limit-connections\n: number of concurrent connections allowed from a single IP address.\n\n\nnginx.ingress.kubernetes.io/limit-rps\n: number of connections that may be accepted from a given IP each second.\n\n\nnginx.ingress.kubernetes.io/limit-rpm\n: number of connections that may be accepted from a given IP each minute.\n\n\nnginx.ingress.kubernetes.io/limit-rate-after\n: sets the initial amount after which the further transmission of a response to a client will be rate limited.\n\n\nnginx.ingress.kubernetes.io/limit-rate\n: rate of request that accepted from a client each second.\n\n\n\n\nYou can specify the client IP source ranges to be excluded from rate-limiting through the \nnginx.ingress.kubernetes.io/limit-whitelist\n annotation. The value is a comma separated list of CIDRs.\n\n\nIf you specify multiple annotations in a single Ingress rule, \nlimit-rpm\n, and then \nlimit-rps\n takes precedence.\n\n\nThe annotation \nnginx.ingress.kubernetes.io/limit-rate\n, \nnginx.ingress.kubernetes.io/limit-rate-after\n define a limit the rate of response transmission to a client. The rate is specified in bytes per second. The zero value disables rate limiting. The limit is set per a request, and so if a client simultaneously opens two connections, the overall rate will be twice as much as the specified limit.\n\n\nTo configure this setting globally for all Ingress rules, the \nlimit-rate-after\n and \nlimit-rate\n value may be set in the \nNGINX ConfigMap\n. if you set the value in ingress annotation will cover global setting.\n\n\nPermanent Redirect\n\u00b6\n\n\nThis annotation allows to return a permanent redirect instead of sending data to the upstream. For example \nnginx.ingress.kubernetes.io/permanent-redirect: https://www.google.com\n would redirect everything to Google.\n\n\nSSL Passthrough\n\u00b6\n\n\nThe annotation \nnginx.ingress.kubernetes.io/ssl-passthrough\n allows to configure TLS termination in the pod and not in NGINX.\n\n\n\n\nAttention\n\n\nUsing the annotation \nnginx.ingress.kubernetes.io/ssl-passthrough\n invalidates all the other available annotations.\nThis is because SSL Passthrough works on level 4 of the OSI stack (TCP), not on the HTTP/HTTPS level.\n\n\n\n\n\n\nAttention\n\n\nThe use of this annotation requires the flag \n--enable-ssl-passthrough\n (By default it is disabled).\n\n\n\n\nSecure backends\n\u00b6\n\n\nBy default NGINX uses plain HTTP to reach the services.\nAdding the annotation \nnginx.ingress.kubernetes.io/secure-backends: \"true\"\n in the Ingress rule changes the protocol to HTTPS.\nIf you want to validate the upstream against a specific certificate, you can create a secret with it and reference the secret with the annotation \nnginx.ingress.kubernetes.io/secure-verify-ca-secret\n.\n\n\n\n\nAttention\n\n\nNote that if an invalid or non-existent secret is given,\nthe ingress controller will ignore the \nsecure-backends\n annotation.\n\n\n\n\nService Upstream\n\u00b6\n\n\nBy default the NGINX ingress controller uses a list of all endpoints (Pod IP/port) in the NGINX upstream configuration.\n\n\nThe \nnginx.ingress.kubernetes.io/service-upstream\n annotation disables that behavior and instead uses a single upstream in NGINX, the service's Cluster IP and port.\n\n\nThis can be desirable for things like zero-downtime deployments as it reduces the need to reload NGINX configuration when Pods come up and down. See issue \n#257\n.\n\n\nKnown Issues\n\u00b6\n\n\nIf the \nservice-upstream\n annotation is specified the following things should be taken into consideration:\n\n\n\n\nSticky Sessions will not work as only round-robin load balancing is supported.\n\n\nThe \nproxy_next_upstream\n directive will not have any effect meaning on error the request will not be dispatched to another upstream.\n\n\n\n\nServer-side HTTPS enforcement through redirect\n\u00b6\n\n\nBy default the controller redirects (308) to HTTPS if TLS is enabled for that ingress.\nIf you want to disable this behavior globally, you can use \nssl-redirect: \"false\"\n in the NGINX \nconfig map\n.\n\n\nTo configure this feature for specific ingress resources, you can use the \nnginx.ingress.kubernetes.io/ssl-redirect: \"false\"\n\nannotation in the particular resource.\n\n\nWhen using SSL offloading outside of cluster (e.g. AWS ELB) it may be useful to enforce a redirect to HTTPS\neven when there is no TLS certificate available.\nThis can be achieved by using the \nnginx.ingress.kubernetes.io/force-ssl-redirect: \"true\"\n annotation in the particular resource.\n\n\nRedirect from/to www.\n\u00b6\n\n\nIn some scenarios is required to redirect from \nwww.domain.com\n to \ndomain.com\n or vice versa.\nTo enable this feature use the annotation \nnginx.ingress.kubernetes.io/from-to-www-redirect: \"true\"\n\n\n\n\nAttention\n\n\nIf at some point a new Ingress is created with a host equal to one of the options (like \ndomain.com\n) the annotation will be omitted.\n\n\n\n\nWhitelist source range\n\u00b6\n\n\nYou can specify allowed client IP source ranges through the \nnginx.ingress.kubernetes.io/whitelist-source-range\n annotation.\nThe value is a comma separated list of \nCIDRs\n, e.g. \n10.0.0.0/24,172.10.0.1\n.\n\n\nTo configure this setting globally for all Ingress rules, the \nwhitelist-source-range\n value may be set in the \nNGINX ConfigMap\n.\n\n\n\n\nNote\n\n\nAdding an annotation to an Ingress rule overrides any global restriction.\n\n\n\n\nCustom timeouts\n\u00b6\n\n\nUsing the configuration configmap it is possible to set the default global timeout for connections to the upstream servers.\nIn some scenarios is required to have different values. To allow this we provide annotations that allows this customization:\n\n\n\n\nnginx.ingress.kubernetes.io/proxy-connect-timeout\n\n\nnginx.ingress.kubernetes.io/proxy-send-timeout\n\n\nnginx.ingress.kubernetes.io/proxy-read-timeout\n\n\nnginx.ingress.kubernetes.io/proxy-next-upstream\n\n\nnginx.ingress.kubernetes.io/proxy-next-upstream-tries\n\n\nnginx.ingress.kubernetes.io/proxy-request-buffering\n\n\n\n\nProxy redirect\n\u00b6\n\n\nWith the annotations \nnginx.ingress.kubernetes.io/proxy-redirect-from\n and \nnginx.ingress.kubernetes.io/proxy-redirect-to\n it is possible to\nset the text that should be changed in the \nLocation\n and \nRefresh\n header fields of a proxied server response (http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_redirect)\n\n\nSetting \"off\" or \"default\" in the annotation \nnginx.ingress.kubernetes.io/proxy-redirect-from\n disables \nnginx.ingress.kubernetes.io/proxy-redirect-to\n,\notherwise, both annotations must be used in unison. Note that each annotation must be a string without spaces.\n\n\nBy default the value of each annotation is \"off\".\n\n\nCustom max body size\n\u00b6\n\n\nFor NGINX, an 413 error will be returned to the client when the size in a request exceeds the maximum allowed size of the client request body. This size can be configured by the parameter \nclient_max_body_size\n.\n\n\nTo configure this setting globally for all Ingress rules, the \nproxy-body-size\n value may be set in the \nNGINX ConfigMap\n.\nTo use custom values in an Ingress rule define these annotation:\n\n\nnginx.ingress.kubernetes.io/proxy-body-size\n:\n \n8m\n\n\n\n\n\n\nProxy buffering\n\u00b6\n\n\nEnable or disable proxy buffering \nproxy_buffering\n.\nBy default proxy buffering is disabled in the NGINX config.\n\n\nTo configure this setting globally for all Ingress rules, the \nproxy-buffering\n value may be set in the \nNGINX ConfigMap\n.\nTo use custom values in an Ingress rule define these annotation:\n\n\nnginx.ingress.kubernetes.io/proxy-buffering\n:\n \n\"on\"\n\n\n\n\n\n\nSSL ciphers\n\u00b6\n\n\nSpecifies the \nenabled ciphers\n.\n\n\nUsing this annotation will set the \nssl_ciphers\n directive at the server level. This configuration is active for all the paths in the host.\n\n\nnginx.ingress.kubernetes.io/ssl-ciphers\n:\n \n\"ALL:!aNULL:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP\"\n\n\n\n\n\n\nConnection proxy header\n\u00b6\n\n\nUsing this annotation will override the default connection header set by NGINX.\nTo use custom values in an Ingress rule, define the annotation:\n\n\nnginx.ingress.kubernetes.io/connection-proxy-header\n:\n \n\"keep-alive\"\n\n\n\n\n\n\nEnable Access Log\n\u00b6\n\n\nAccess logs are enabled by default, but in some scenarios access logs might be required to be disabled for a given\ningress. To do this, use the annotation:\n\n\nnginx.ingress.kubernetes.io/enable-access-log\n:\n \n\"false\"\n\n\n\n\n\n\nEnable Rewrite Log\n\u00b6\n\n\nRewrite logs are not enabled by default. In some scenarios it could be required to enable NGINX rewrite logs.\nNote that rewrite logs are sent to the error_log file at the notice level. To enable this feature use the annotation:\n\n\nnginx.ingress.kubernetes.io/enable-rewrite-log\n:\n \n\"true\"\n\n\n\n\n\n\nLua Resty WAF\n\u00b6\n\n\nUsing \nlua-resty-waf-*\n annotations we can enable and control the \nlua-resty-waf\n\nWeb Application Firewall per location.\n\n\nFollowing configuration will enable the WAF for the paths defined in the corresponding ingress:\n\n\nnginx.ingress.kubernetes.io/lua-resty-waf\n:\n \n\"active\"\n\n\n\n\n\n\nIn order to run it in debugging mode you can set \nnginx.ingress.kubernetes.io/lua-resty-waf-debug\n to \n\"true\"\n in addition to the above configuration.\nThe other possible values for \nnginx.ingress.kubernetes.io/lua-resty-waf\n are \ninactive\n and \nsimulate\n.\nIn \ninactive\n mode WAF won't do anything, whereas in \nsimulate\n mode it will log a warning message if there's a matching WAF rule for given request. This is useful to debug a rule and eliminate possible false positives before fully deploying it.\n\n\nlua-resty-waf\n comes with predefined set of rules \nhttps://github.com/p0pr0ck5/lua-resty-waf/tree/84b4f40362500dd0cb98b9e71b5875cb1a40f1ad/rules\n that covers ModSecurity CRS.\nYou can use \nnginx.ingress.kubernetes.io/lua-resty-waf-ignore-rulesets\n to ignore a subset of those rulesets. For an example:\n\n\nnginx.ingress.kubernetes.io/lua-resty-waf-ignore-rulesets\n:\n \n\"41000_sqli,\n \n42000_xss\"\n\n\n\n\n\n\nwill ignore the two mentioned rulesets.\n\n\nIt is also possible to configure custom WAF rules per ingress using the \nnginx.ingress.kubernetes.io/lua-resty-waf-extra-rules\n annotation. For an example the following snippet will configure a WAF rule to deny requests with query string value that contains word \nfoo\n:\n\n\nnginx.ingress.kubernetes.io/lua-resty-waf-extra-rules\n:\n \n'[=[\n \n{\n \n\"access\":\n \n[\n \n{\n \n\"actions\":\n \n{\n \n\"disrupt\"\n \n:\n \n\"DENY\"\n \n},\n \n\"id\":\n \n10001,\n \n\"msg\":\n \n\"my\n \ncustom\n \nrule\",\n \n\"operator\":\n \n\"STR_CONTAINS\",\n \n\"pattern\":\n \n\"foo\",\n \n\"vars\":\n \n[\n \n{\n \n\"parse\":\n \n[\n \n\"values\",\n \n1\n \n],\n \n\"type\":\n \n\"REQUEST_ARGS\"\n \n}\n \n]\n \n}\n \n],\n \n\"body_filter\":\n \n[],\n \n\"header_filter\":[]\n \n}\n \n]=]'\n\n\n\n\n\n\nFor details on how to write WAF rules, please refer to \nhttps://github.com/p0pr0ck5/lua-resty-waf\n.\n\n\ngRPC backend\n\u00b6\n\n\nSince NGINX 1.13.10 it is possible to expose \ngRPC services natively\n\n\nYou only need to add the annotation \nnginx.ingress.kubernetes.io/grpc-backend: \"true\"\n to enable this feature.\nAdditionally, if the gRPC service requires TLS, add \nnginx.ingress.kubernetes.io/secure-backends: \"true\"\n.\n\n\n\n\nAttention\n\n\nThis feature requires HTTP2 to work which means we need to expose this service using HTTPS.\nExposing a gRPC service using HTTP is not supported.", + "text": "Annotations\n\u00b6\n\n\nYou can add these Kubernetes annotations to specific Ingress

some scenarios the exposed URL in the backend service differs from the specified path in the Ingress rule. Without a rewrite any request will return 404.\nSet the annotation \nnginx.ingress.kubernetes.io/rewrite-target\n to the path expected by the service.\n\n\nIf the application contains relative links it is possible to add an additional annotation \nnginx.ingress.kubernetes.io/add-base-url\n that will prepend a \nbase\n tag\n in the header of the returned HTML from the backend.\n\n\nIf the scheme of \nbase\n tag\n need to be specific, set the annotation \nnginx.ingress.kubernetes.io/base-url-scheme\n to the scheme such as \nhttp\n and \nhttps\n.\n\n\nIf the Application Root is exposed in a different path and needs to be redirected, set the annotation \nnginx.ingress.kubernetes.io/app-root\n to redirect requests for \n/\n.\n\n\n\n\nExample\n\n\nPlease check the \nrewrite\n example.\n\n\n\n\nSession Affinity\n\u00b6\n\n\nThe annotation \nnginx.ingress.kubernetes.io/affinity\n enables and sets the affinity type in all Upstreams of an Ingress. This way, a request will always be directed to the same upstream server.\nThe only affinity type available for NGINX is \ncookie\n.\n\n\n\n\nExample\n\n\nPlease check the \naffinity\n example.\n\n\n\n\nCookie affinity\n\u00b6\n\n\nIf you use the \ncookie\n affinity type you can also specify the name of the cookie that will be used to route the requests with the annotation \nnginx.ingress.kubernetes.io/session-cookie-name\n. The default is to create a cookie named 'INGRESSCOOKIE'.\n\n\nIn case of NGINX the annotation \nnginx.ingress.kubernetes.io/session-cookie-hash\n defines which algorithm will be used to hash the used upstream. Default value is \nmd5\n and possible values are \nmd5\n, \nsha1\n and \nindex\n.\n\n\n\n\nAttention\n\n\nThe \nindex\n option is not an actual hash; an in-memory index is used instead, which has less overhead.\nHowever, with \nindex\n, matching against a changing upstream server list is inconsistent.\nSo, at reload, if upstream servers have changed, index values are not guaranteed to correspond to the same server as before!\n\nUse \nindex\n with caution\n and only if you need to!\n\n\n\n\nIn NGINX this feature is implemented by the third party module \nnginx-sticky-module-ng\n. The workflow used to define which upstream server will be used is explained \nhere\n\n\nAuthentication\n\u00b6\n\n\nIs possible to add authentication adding additional annotations in the Ingress rule. The source of the authentication is a secret that contains usernames and passwords inside the key \nauth\n.\n\n\nThe annotations are:\n\n\nnginx.ingress.kubernetes.io/auth-type: [basic|digest]\n\n\n\n\n\nIndicates the \nHTTP Authentication Type: Basic or Digest Access Authentication\n.\n\n\nnginx.ingress.kubernetes.io/auth-secret: secretName\n\n\n\n\n\nThe name of the Secret that contains the usernames and passwords which are granted access to the \npath\ns defined in the Ingress rules.\nThis annotation also accepts the alternative form \"namespace/secretName\", in which case the Secret lookup is performed in the referenced namespace instead of the Ingress namespace.\n\n\nnginx.ingress.kubernetes.io/auth-realm: \"realm string\"\n\n\n\n\n\n\n\nExample\n\n\nPlease check the \nauth\n example.\n\n\n\n\nCustom NGINX upstream checks\n\u00b6\n\n\nNGINX exposes some flags in the \nupstream configuration\n that enable the configuration of each server in the upstream. The Ingress controller allows custom \nmax_fails\n and \nfail_timeout\n parameters in a global context using \nupstream-max-fails\n and \nupstream-fail-timeout\n in the NGINX ConfigMap or in a particular Ingress rule. \nupstream-max-fails\n defaults to 0. This means NGINX will respect the container's \nreadinessProbe\n if it is defined. If there is no probe and no values for \nupstream-max-fails\n NGINX will continue to send traffic to the container.\n\n\n\n\nTip\n\n\nWith the default configuration NGINX will not health check your backends. Whenever the endpoints controller notices a readiness probe failure, that pod's IP will be removed from the list of endpoints. This will trigger the NGINX controller to also remove it from the upstreams.**\n\n\n\n\nTo use custom values in an Ingress rule define these annotations:\n\n\nnginx.ingress.kubernetes.io/upstream-max-fails\n: number of unsuccessful attempts to communicate with the server that should occur in the duration set by the \nupstream-fail-timeout\n parameter to consider the server unavailable.\n\n\nnginx.ingress.kubernetes.io/upstream-fail-timeout\n: time in seconds during which the specified number of unsuccessful attempts to communicate with the server should occur to consider the server unavailable. This is also the period of time the server will be considered unavailable.\n\n\nIn NGINX, backend server pools are called \"\nupstreams\n\". Each upstream contains the endpoints for a service. An upstream is created for each service that has Ingress rules defined.\n\n\n\n\nAttention\n\n\nAll Ingress rules using the same service will use the same upstream.\n\nOnly one of the Ingress rules should define annotations to configure the upstream servers.\n\n\n\n\n\n\nExample\n\n\nPlease check the \ncustom upstream check\n example.\n\n\n\n\nCustom NGINX upstream hashing\n\u00b6\n\n\nNGINX supports load balancing by client-server mapping based on \nconsistent hashing\n for a given key. The key can contain text, variables or any combination thereof. This feature allows for request stickiness other than client IP or cookies. The \nketama\n consistent hashing method will be used which ensures only a few keys would be remapped to different servers on upstream group changes.\n\n\nTo enable consistent hashing for a backend:\n\n\nnginx.ingress.kubernetes.io/upstream-hash-by\n: the nginx variable, text value or any combination thereof to use for consistent hashing. For example \nnginx.ingress.kubernetes.io/upstream-hash-by: \"$request_uri\"\n to consistently hash upstream requests by the current request URI.\n\n\nCustom NGINX load balancing\n\u00b6\n\n\nThis is similar to (https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/configmap.md#load-balance) but configures load balancing algorithm per ingress.\n\n\n\n\nNote that \nnginx.ingress.kubernetes.io/upstream-hash-by\n takes preference over this. If this and \nnginx.ingress.kubernetes.io/upstream-hash-by\n are not set then we fallback to using globally configured load balancing algorithm.\n\n\n\n\nCustom NGINX upstream vhost\n\u00b6\n\n\nThis configuration setting allows you to control the value for host in the following statement: \nproxy_set_header Host $host\n, which forms part of the location block. This is useful if you need to call the upstream server by something other than \n$host\n.\n\n\nClient Certificate Authentication\n\u00b6\n\n\nIt is possible to enable Client Certificate Authentication using additional annotations in Ingress Rule.\n\n\nThe annotations are:\n\n\n\n\nnginx.ingress.kubernetes.io/auth-tls-secret: secretName\n:\n The name of the Secret that contains the full Certificate Authority chain \nca.crt\n that is enabled to authenticate against this Ingress.\n This annotation also accepts the alternative form \"namespace/secretName\", in which case the Secret lookup is performed in the referenced namespace instead of the Ingress namespace.\n\n\nnginx.ingress.kubernetes.io/auth-tls-verify-depth\n:\n The validation depth between the provided client certificate and the Certification Authority chain.\n\n\nnginx.ingress.kubernetes.io/auth-tls-verify-client\n:\n Enables verification of client certificates.\n\n\nnginx.ingress.kubernetes.io/auth-tls-error-page\n:\n The URL/Page that user should be redirected in case of a Certificate Authentication Error\n\n\nnginx.ingress.kubernetes.io/auth-tls-pass-certificate-to-upstream\n:\n Indicates if the received certificates should be passed or not to the upstream server. By default this is disabled.\n\n\n\n\n\n\nExample\n\n\nPlease check the \nclient-certs\n example.\n\n\n\n\n\n\nAttention\n\n\nTLS with Client Authentication is \nnot\n possible in Cloudflare and might result in unexpected behavior.\n\n\nCloudflare only allows Authenticated Origin Pulls and is required to use their own certificate: \nhttps://blog.cloudflare.com/protecting-the-origin-with-tls-authenticated-origin-pulls/\n\n\nOnly Authenticated Origin Pulls are allowed and can be configured by following their tutorial: \nhttps://support.cloudflare.com/hc/en-us/articles/204494148-Setting-up-NGINX-to-use-TLS-Authenticated-Origin-Pulls\n\n\n\n\nConfiguration snippet\n\u00b6\n\n\nUsing this annotation you can add additional configuration to the NGINX location. For example:\n\n\nnginx.ingress.kubernetes.io/configuration-snippet\n:\n \n|\n\n \nmore_set_headers \"Request-Id: $req_id\";\n\n\n\n\n\n\nDefault Backend\n\u00b6\n\n\nThe ingress controller requires a \ndefault backend\n.\nThis service handles the response when the service in the Ingress rule does not have endpoints.\nThis is a global configuration for the ingress controller. In some cases could be required to return a custom content or format. In this scenario we can use the annotation \nnginx.ingress.kubernetes.io/default-backend: \n to specify a custom default backend.\n\n\nEnable CORS\n\u00b6\n\n\nTo enable Cross-Origin Resource Sharing (CORS) in an Ingress rule,\nadd the annotation \nnginx.ingress.kubernetes.io/enable-cors: \"true\"\n.\nThis will add a section in the server location enabling this functionality.\n\n\nCORS can be controlled with the following annotations:\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-methods\n\n controls which methods are accepted.\n This is a multi-valued field, separated by ',' and accepts only letters (upper and lower case).\n Example: \nnginx.ingress.kubernetes.io/cors-allow-methods: \"PUT, GET, POST, OPTIONS\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-headers\n\n controls which headers are accepted.\n This is a multi-valued field, separated by ',' and accepts letters, numbers, _ and -.\n Example: \nnginx.ingress.kubernetes.io/cors-allow-headers: \"X-Forwarded-For, X-app123-XPTO\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-origin\n\n controls what's the accepted Origin for CORS and defaults to '*'.\n This is a single field value, with the following format: \nhttp(s)://origin-site.com\n or \nhttp(s)://origin-site.com:port\n\n Example: \nnginx.ingress.kubernetes.io/cors-allow-origin: \"https://origin-site.com:4443\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-allow-credentials\n\n controls if credentials can be passed during CORS operations.\n Example: \nnginx.ingress.kubernetes.io/cors-allow-credentials: \"true\"\n\n\n\n\n\n\nnginx.ingress.kubernetes.io/cors-max-age\n\n controls how long preflight requests can be cached.\n Example: \nnginx.ingress.kubernetes.io/cors-max-age: 600\n\n\n\n\n\n\n\n\nNote\n\n\nFor more information please see \nhttps://enable-cors.org\n\n\n\n\nServer Alias\n\u00b6\n\n\nTo add Server Aliases to an Ingress rule add the annotation \nnginx.ingress.kubernetes.io/server-alias: \"\"\n.\nThis will create a server with the same configuration, but a different \nserver_name\n as the provided host.\n\n\n\n\nNote\n\n\nA server-alias name cannot conflict with the hostname of an existing server. If it does the server-alias annotation will be ignored.\nIf a server-alias is created and later a new server with the same hostname is created,\nthe new server configuration will take place over the alias configuration.\n\n\n\n\nFor more information please see \nthe \nserver_name\n documentation\n.\n\n\nServer snippet\n\u00b6\n\n\nUsing the annotation \nnginx.ingress.kubernetes.io/server-snippet\n it is possible to add custom configuration in the server configuration block.\n\n\napiVersion\n:\n \nextensions/v1beta1\n\n\nkind\n:\n \nIngress\n\n\nmetadata\n:\n\n \nannotations\n:\n\n \nnginx.ingress.kubernetes.io/server-snippet\n:\n \n|\n\n\nset $agentflag 0;\n\n\n\nif ($http_user_agent ~* \"(Mobile)\" ){\n\n \nset $agentflag 1;\n\n\n}\n\n\n\nif ( $agentflag = 1 ) {\n\n \nreturn 301 https://m.example.com;\n\n\n}\n\n\n\n\n\n\n\n\nAttention\n\n\nThis annotation can be used only once per host.\n\n\n\n\nClient Body Buffer Size\n\u00b6\n\n\nSets buffer size for reading client request body per location. In case the request body is larger than the buffer,\nthe whole body or only its part is written to a temporary file. By default, buffer size is equal to two memory pages.\nThis is 8K on x86, other 32-bit platforms, and x86-64. It is usually 16K on other 64-bit platforms. This annotation is\napplied to each location provided in the ingress rule.\n\n\n\n\nNote\n\n\nThe annotation value must be given in a format understood by Nginx.\n\n\n\n\n\n\nExample\n\n\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: \"1000\"\n # 1000 bytes\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1k\n # 1 kilobyte\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1K\n # 1 kilobyte\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1m\n # 1 megabyte\n\n\nnginx.ingress.kubernetes.io/client-body-buffer-size: 1M\n # 1 megabyte\n\n\n\n\n\n\nFor more information please see \nhttp://nginx.org\n\n\nExternal Authentication\n\u00b6\n\n\nTo use an existing service that provides authentication the Ingress rule can be annotated with \nnginx.ingress.kubernetes.io/auth-url\n to indicate the URL where the HTTP request should be sent.\n\n\nnginx.ingress.kubernetes.io/auth-url\n:\n \n\"URL\n \nto\n \nthe\n \nauthentication\n \nservice\"\n\n\n\n\n\n\nAdditionally it is possible to set:\n\n\n\n\nnginx.ingress.kubernetes.io/auth-method\n:\n \n\n to specify the HTTP method to use.\n\n\nnginx.ingress.kubernetes.io/auth-signin\n:\n \n\n to specify the location of the error page.\n\n\nnginx.ingress.kubernetes.io/auth-response-headers\n:\n \n\n to specify headers to pass to backend once authentication request completes.\n\n\nnginx.ingress.kubernetes.io/auth-request-redirect\n:\n \n\n to specify the X-Auth-Request-Redirect header value.\n\n\n\n\n\n\nExample\n\n\nPlease check the \nexternal-auth\n example.\n\n\n\n\nRate limiting\n\u00b6\n\n\nThese annotations define a limit on the connections that can be opened by a single client IP address.\nThis can be used to mitigate \nDDoS Attacks\n.\n\n\n\n\nnginx.ingress.kubernetes.io/limit-connections\n: number of concurrent connections allowed from a single IP address.\n\n\nnginx.ingress.kubernetes.io/limit-rps\n: number of connections that may be accepted from a given IP each second.\n\n\nnginx.ingress.kubernetes.io/limit-rpm\n: number of connections that may be accepted from a given IP each minute.\n\n\nnginx.ingress.kubernetes.io/limit-rate-after\n: sets the initial amount after which the further transmission of a response to a client will be rate limited.\n\n\nnginx.ingress.kubernetes.io/limit-rate\n: rate of request that accepted from a client each second.\n\n\n\n\nYou can specify the client IP source ranges to be excluded from rate-limiting through the \nnginx.ingress.kubernetes.io/limit-whitelist\n annotation. The value is a comma separated list of CIDRs.\n\n\nIf you specify multiple annotations in a single Ingress rule, \nlimit-rpm\n, and then \nlimit-rps\n takes precedence.\n\n\nThe annotation \nnginx.ingress.kubernetes.io/limit-rate\n, \nnginx.ingress.kubernetes.io/limit-rate-after\n define a limit the rate of response transmission to a client. The rate is specified in bytes per second. The zero value disables rate limiting. The limit is set per a request, and so if a client simultaneously opens two connections, the overall rate will be twice as much as the specified limit.\n\n\nTo configure this setting globally for all Ingress rules, the \nlimit-rate-after\n and \nlimit-rate\n value may be set in the \nNGINX ConfigMap\n. if you set the value in ingress annotation will cover global setting.\n\n\nPermanent Redirect\n\u00b6\n\n\nThis annotation allows to return a permanent redirect instead of sending data to the upstream. For example \nnginx.ingress.kubernetes.io/permanent-redirect: https://www.google.com\n would redirect everything to Google.\n\n\nSSL Passthrough\n\u00b6\n\n\nThe annotation \nnginx.ingress.kubernetes.io/ssl-passthrough\n allows to configure TLS termination in the pod and not in NGINX.\n\n\n\n\nAttention\n\n\nUsing the annotation \nnginx.ingress.kubernetes.io/ssl-passthrough\n invalidates all the other available annotations.\nThis is because SSL Passthrough works on level 4 of the OSI stack (TCP), not on the HTTP/HTTPS level.\n\n\n\n\n\n\nAttention\n\n\nThe use of this annotation requires the flag \n--enable-ssl-passthrough\n (By default it is disabled).\n\n\n\n\nSecure backends\n\u00b6\n\n\nBy default NGINX uses plain HTTP to reach the services.\nAdding the annotation \nnginx.ingress.kubernetes.io/secure-backends: \"true\"\n in the Ingress rule changes the protocol to HTTPS.\nIf you want to validate the upstream against a specific certificate, you can create a secret with it and reference the secret with the annotation \nnginx.ingress.kubernetes.io/secure-verify-ca-secret\n.\n\n\n\n\nAttention\n\n\nNote that if an invalid or non-existent secret is given,\nthe ingress controller will ignore the \nsecure-backends\n annotation.\n\n\n\n\nService Upstream\n\u00b6\n\n\nBy default the NGINX ingress controller uses a list of all endpoints (Pod IP/port) in the NGINX upstream configuration.\n\n\nThe \nnginx.ingress.kubernetes.io/service-upstream\n annotation disables that behavior and instead uses a single upstream in NGINX, the service's Cluster IP and port.\n\n\nThis can be desirable for things like zero-downtime deployments as it reduces the need to reload NGINX configuration when Pods come up and down. See issue \n#257\n.\n\n\nKnown Issues\n\u00b6\n\n\nIf the \nservice-upstream\n annotation is specified the following things should be taken into consideration:\n\n\n\n\nSticky Sessions will not work as only round-robin load balancing is supported.\n\n\nThe \nproxy_next_upstream\n directive will not have any effect meaning on error the request will not be dispatched to another upstream.\n\n\n\n\nServer-side HTTPS enforcement through redirect\n\u00b6\n\n\nBy default the controller redirects (308) to HTTPS if TLS is enabled for that ingress.\nIf you want to disable this behavior globally, you can use \nssl-redirect: \"false\"\n in the NGINX \nconfig map\n.\n\n\nTo configure this feature for specific ingress resources, you can use the \nnginx.ingress.kubernetes.io/ssl-redirect: \"false\"\n\nannotation in the particular resource.\n\n\nWhen using SSL offloading outside of cluster (e.g. AWS ELB) it may be useful to enforce a redirect to HTTPS\neven when there is no TLS certificate available.\nThis can be achieved by using the \nnginx.ingress.kubernetes.io/force-ssl-redirect: \"true\"\n annotation in the particular resource.\n\n\nRedirect from/to www.\n\u00b6\n\n\nIn some scenarios is required to redirect from \nwww.domain.com\n to \ndomain.com\n or vice versa.\nTo enable this feature use the annotation \nnginx.ingress.kubernetes.io/from-to-www-redirect: \"true\"\n\n\n\n\nAttention\n\n\nIf at some point a new Ingress is created with a host equal to one of the options (like \ndomain.com\n) the annotation will be omitted.\n\n\n\n\nWhitelist source range\n\u00b6\n\n\nYou can specify allowed client IP source ranges through the \nnginx.ingress.kubernetes.io/whitelist-source-range\n annotation.\nThe value is a comma separated list of \nCIDRs\n, e.g. \n10.0.0.0/24,172.10.0.1\n.\n\n\nTo configure this setting globally for all Ingress rules, the \nwhitelist-source-range\n value may be set in the \nNGINX ConfigMap\n.\n\n\n\n\nNote\n\n\nAdding an annotation to an Ingress rule overrides any global restriction.\n\n\n\n\nCustom timeouts\n\u00b6\n\n\nUsing the configuration configmap it is possible to set the default global timeout for connections to the upstream servers.\nIn some scenarios is required to have different values. To allow this we provide annotations that allows this customization:\n\n\n\n\nnginx.ingress.kubernetes.io/proxy-connect-timeout\n\n\nnginx.ingress.kubernetes.io/proxy-send-timeout\n\n\nnginx.ingress.kubernetes.io/proxy-read-timeout\n\n\nnginx.ingress.kubernetes.io/proxy-next-upstream\n\n\nnginx.ingress.kubernetes.io/proxy-next-upstream-tries\n\n\nnginx.ingress.kubernetes.io/proxy-request-buffering\n\n\n\n\nProxy redirect\n\u00b6\n\n\nWith the annotations \nnginx.ingress.kubernetes.io/proxy-redirect-from\n and \nnginx.ingress.kubernetes.io/proxy-redirect-to\n it is possible to\nset the text that should be changed in the \nLocation\n and \nRefresh\n header fields of a proxied server response (http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_redirect)\n\n\nSetting \"off\" or \"default\" in the annotation \nnginx.ingress.kubernetes.io/proxy-redirect-from\n disables \nnginx.ingress.kubernetes.io/proxy-redirect-to\n,\notherwise, both annotations must be used in unison. Note that each annotation must be a string without spaces.\n\n\nBy default the value of each annotation is \"off\".\n\n\nCustom max body size\n\u00b6\n\n\nFor NGINX, an 413 error will be returned to the client when the size in a request exceeds the maximum allowed size of the client request body. This size can be configured by the parameter \nclient_max_body_size\n.\n\n\nTo configure this setting globally for all Ingress rules, the \nproxy-body-size\n value may be set in the \nNGINX ConfigMap\n.\nTo use custom values in an Ingress rule define these annotation:\n\n\nnginx.ingress.kubernetes.io/proxy-body-size\n:\n \n8m\n\n\n\n\n\n\nProxy buffering\n\u00b6\n\n\nEnable or disable proxy buffering \nproxy_buffering\n.\nBy default proxy buffering is disabled in the NGINX config.\n\n\nTo configure this setting globally for all Ingress rules, the \nproxy-buffering\n value may be set in the \nNGINX ConfigMap\n.\nTo use custom values in an Ingress rule define these annotation:\n\n\nnginx.ingress.kubernetes.io/proxy-buffering\n:\n \n\"on\"\n\n\n\n\n\n\nSSL ciphers\n\u00b6\n\n\nSpecifies the \nenabled ciphers\n.\n\n\nUsing this annotation will set the \nssl_ciphers\n directive at the server level. This configuration is active for all the paths in the host.\n\n\nnginx.ingress.kubernetes.io/ssl-ciphers\n:\n \n\"ALL:!aNULL:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP\"\n\n\n\n\n\n\nConnection proxy header\n\u00b6\n\n\nUsing this annotation will override the default connection header set by NGINX.\nTo use custom values in an Ingress rule, define the annotation:\n\n\nnginx.ingress.kubernetes.io/connection-proxy-header\n:\n \n\"keep-alive\"\n\n\n\n\n\n\nEnable Access Log\n\u00b6\n\n\nAccess logs are enabled by default, but in some scenarios access logs might be required to be disabled for a given\ningress. To do this, use the annotation:\n\n\nnginx.ingress.kubernetes.io/enable-access-log\n:\n \n\"false\"\n\n\n\n\n\n\nEnable Rewrite Log\n\u00b6\n\n\nRewrite logs are not enabled by default. In some scenarios it could be required to enable NGINX rewrite logs.\nNote that rewrite logs are sent to the error_log file at the notice level. To enable this feature use the annotation:\n\n\nnginx.ingress.kubernetes.io/enable-rewrite-log\n:\n \n\"true\"\n\n\n\n\n\n\nLua Resty WAF\n\u00b6\n\n\nUsing \nlua-resty-waf-*\n annotations we can enable and control the \nlua-resty-waf\n\nWeb Application Firewall per location.\n\n\nFollowing configuration will enable the WAF for the paths defined in the corresponding ingress:\n\n\nnginx.ingress.kubernetes.io/lua-resty-waf\n:\n \n\"active\"\n\n\n\n\n\n\nIn order to run it in debugging mode you can set \nnginx.ingress.kubernetes.io/lua-resty-waf-debug\n to \n\"true\"\n in addition to the above configuration.\nThe other possible values for \nnginx.ingress.kubernetes.io/lua-resty-waf\n are \ninactive\n and \nsimulate\n.\nIn \ninactive\n mode WAF won't do anything, whereas in \nsimulate\n mode it will log a warning message if there's a matching WAF rule for given request. This is useful to debug a rule and eliminate possible false positives before fully deploying it.\n\n\nlua-resty-waf\n comes with predefined set of rules \nhttps://github.com/p0pr0ck5/lua-resty-waf/tree/84b4f40362500dd0cb98b9e71b5875cb1a40f1ad/rules\n that covers ModSecurity CRS.\nYou can use \nnginx.ingress.kubernetes.io/lua-resty-waf-ignore-rulesets\n to ignore a subset of those rulesets. For an example:\n\n\nnginx.ingress.kubernetes.io/lua-resty-waf-ignore-rulesets\n:\n \n\"41000_sqli,\n \n42000_xss\"\n\n\n\n\n\n\nwill ignore the two mentioned rulesets.\n\n\nIt is also possible to configure custom WAF rules per ingress using the \nnginx.ingress.kubernetes.io/lua-resty-waf-extra-rules\n annotation. For an example the following snippet will configure a WAF rule to deny requests with query string value that contains word \nfoo\n:\n\n\nnginx.ingress.kubernetes.io/lua-resty-waf-extra-rules\n:\n \n'[=[\n \n{\n \n\"access\":\n \n[\n \n{\n \n\"actions\":\n \n{\n \n\"disrupt\"\n \n:\n \n\"DENY\"\n \n},\n \n\"id\":\n \n10001,\n \n\"msg\":\n \n\"my\n \ncustom\n \nrule\",\n \n\"operator\":\n \n\"STR_CONTAINS\",\n \n\"pattern\":\n \n\"foo\",\n \n\"vars\":\n \n[\n \n{\n \n\"parse\":\n \n[\n \n\"values\",\n \n1\n \n],\n \n\"type\":\n \n\"REQUEST_ARGS\"\n \n}\n \n]\n \n}\n \n],\n \n\"body_filter\":\n \n[],\n \n\"header_filter\":[]\n \n}\n \n]=]'\n\n\n\n\n\n\nFor details on how to write WAF rules, please refer to \nhttps://github.com/p0pr0ck5/lua-resty-waf\n.\n\n\ngRPC backend\n\u00b6\n\n\nSince NGINX 1.13.10 it is possible to expose \ngRPC services natively\n\n\nYou only need to add the annotation \nnginx.ingress.kubernetes.io/grpc-backend: \"true\"\n to enable this feature.\nAdditionally, if the gRPC service requires TLS, add \nnginx.ingress.kubernetes.io/secure-backends: \"true\"\n.\n\n\n\n\nAttention\n\n\nThis feature requires HTTP2 to work which means we need to expose this service using HTTPS.\nExposing a gRPC service using HTTP is not supported.\n\n\n\n\nInfluxDB\n\u00b6\n\n\nUsing \ninfluxdb-*\n annotations we can monitor requests passing through a Location by sending them to an InfluxDB backend exposing the UDP socket\nusing the \nnginx-influxdb-module\n.\n\n\nnginx.ingress.kubernetes.io/enable-influxdb\n:\n \n\"true\"\n\n\nnginx.ingress.kubernetes.io/influxdb-measurement\n:\n \n\"nginx-reqs\"\n\n\nnginx.ingress.kubernetes.io/influxdb-port\n:\n \n\"8089\"\n\n\nnginx.ingress.kubernetes.io/influxdb-host\n:\n \n\"influxdb\"\n\n\nnginx.ingress.kubernetes.io/influxdb-server-name\n:\n \n\"nginx-ingress\"\n\n\n\n\n\n\nFor the \ninfluxdb-host\n parameter you have two options:\n\n\nTo use the module in the Kubernetes Nginx ingress controller, you have two options:\n\n\n\n\nUse an InfluxDB server configured to enable the \nUDP protocol\n.\n\n\nDeploy Telegraf as a sidecar proxy to the Ingress controller configured to listen UDP with the \nsocket listener input\n and to write using\nanyone of the \noutputs plugins", "title": "Annotations" }, { "location": "/user-guide/nginx-configuration/annotations/#annotations", - "text": "You can add these Kubernetes annotations to specific Ingress objects to customize their behavior.
