|
|

|
|
|
This example uses 2 different certificates to terminate SSL for 2 hostnames.

|
|
|
1. Create tls secrets for foo.bar.com and bar.baz.com as indicated in the yaml
|
|
|
|
|
2. Create [multi-tls.yaml](multi-tls.yaml)
|

|
|
|
|
|
|
|
|
This should generate a segment like:
|
|
|
|
|
```console
|
2021-11-28 21:11:22 +00:00
|
|
|
$ kubectl exec -it ingress-nginx-controller-6vwd1 -- cat /etc/nginx/nginx.conf | grep "foo.bar.com" -B 7 -A 35
|
2017-03-08 12:02:13 +00:00
|
|
|
server {
|
|
|
|
|
listen 80;
|
|
|
|
|
listen 443 ssl http2;
|
|
|
|
|
ssl_certificate /etc/nginx-ssl/default-foobar.pem;
|
|
|
|
|
ssl_certificate_key /etc/nginx-ssl/default-foobar.pem;
|
|
|
|
|
|
|

|

|

|
|

|

|
|
|
if ($scheme = http) {
|
|
|
|
|
return 301 https://$host$request_uri;
|

|

}
|
|
|
|

|
|

location / {

proxy_set_header Host $host;
|

|
|
|
|
# Pass Real IP

|

|

proxy_set_header X-Real-IP $remote_addr;
|

|
|
|

proxy_set_header Upgrade $http_upgrade;

|

|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
proxy_redirect off;
|
|
|
|
|
proxy_buffering off;
|
|
|
|
|
|
|
|
|
|
proxy_http_version 1.1;
|
|
|
|
|
|
2017-10-13 13:55:03 +00:00
|
|
|
proxy_pass http://default-http-svc-80;
|
2017-03-08 12:02:13 +00:00
|
|
|
}
|
|
|
|
|
```
|
|
|
|

|
|
And you should be able to reach your nginx service or http-svc service using a hostname switch:
|
2017-03-08 12:02:13 +00:00
|
|
|
```console
|
|
|
|
|
$ kubectl get ing
|
|
|
|
|
