nginx k8s ingress - forcing www AND https?
I have the following doing the job with the latest nginx-ingress 0.25.1
:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-rule-web
annotations:
kubernetes.io/ingress.class: nginx
certmanager.k8s.io/cluster-issuer: letsencrypt-prod
nginx.ingress.kubernetes.io/from-to-www-redirect: 'true'
spec:
rules:
- host: foo.org
http:
paths:
- path: /
backend:
serviceName: web
servicePort: 80
tls:
- hosts:
- foo.org
- www.foo.org
secretName: letsencrypt-prod
You need to add the certificate for the domain you want to be redirected:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: foo-https-ingress
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/from-to-www-redirect: "true"
spec:
rules:
- host: foo.com
http:
paths:
- backend:
serviceName: foo-prod-front
servicePort: 80
path: /
- host: www.foo.com
http:
paths:
- backend:
serviceName: foo-prod-front
servicePort: 80
path: /
tls:
- hosts:
- foo.com
- www.foo.com
secretName: tls-secret
I am not completely sure, whether from-to-www-redirect
works with this setup, but you can replace it with the following lines, which do work:
nginx.ingress.kubernetes.io/configuration-snippet: |
if ($host = 'foo.com' ) {
rewrite ^ https://www.foo.com$request_uri permanent;
}
