@ -137,6 +138,11 @@ To enable consistent hashing for a backend:
`nginx.ingress.kubernetes.io/upstream-hash-by`: the nginx variable, text value or any combination thereof to use for consistent hashing. For example `nginx.ingress.kubernetes.io/upstream-hash-by: "$request_uri"` to consistently hash upstream requests by the current request URI.
### Custom NGINX load balancing
This is similar to https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/configmap.md#load-balance but configures load balancing algorithm per ingress.
Note that `nginx.ingress.kubernetes.io/upstream-hash-by` takes preference over this. If this and `nginx.ingress.kubernetes.io/upstream-hash-by` are not set then we fallback to using globally configured load balancing algorithm.
### Custom NGINX upstream vhost
This configuration setting allows you to control the value for host in the following statement: `proxy_set_header Host $host`, which forms part of the location block. This is useful if you need to call the upstream server by something other than `$host`.
