I am trying to use kubernetes nginx ingress controller: (quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.22.0). Below is my ingress object.
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: cc-store-ingress
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/rewrite-target: /$1
nginx.ingress.kubernetes.io/add-base-url: "true"
#nginx.ingress.kubernetes.io/configuration-snippet: |
# sub_filter "http://my-ip:30021/" "http://my-ip:30021/app/";
# sub_filter_once off;
spec:
#tls:
#- secretName: tls-secret
rules:
- host: my-ip
http:
paths:
- path: /app/?(.*)
backend:
serviceName: appsvc
servicePort: 7201When I try to access the this service via ingress I hit a blank page, which I understand is because response (set of few java scripts , css and others) are returning to my-ip:30021/ instead of my-ip:30021/app. (checked the nginx logs initial connection gives 200 response subsequent loading of css and js are failing with 404)
Is there a way to overcome this? Neither "sub_filter" nor add-base-url annotations helped.
Is there any way to achieve the path rewriting for response. Would using any other ingress controller (instead of nginx) can make this easier to overcome ?
This is a sample of how I did adding base path to a service which completely doesn't support it. As well a solution for handling redirects to the urls without base path.
annotations:
kubernetes.io/ingress.class: nginx
# catch $1 from 'path' capture group
nginx.ingress.kubernetes.io/rewrite-target: /$1
# handle redirects
# nginx.ingress.kubernetes.io/proxy-redirect-from: http://<host>/
# nginx.ingress.kubernetes.io/proxy-redirect-to: /<basePath>/
nginx.ingress.kubernetes.io/configuration-snippet:
proxy_set_header Accept-Encoding "";
sub_filter_last_modified off;
# add base path to all static resources
sub_filter '<head>' '<head> <base href="/<basePath>/">';
sub_filter 'href="/' 'href="';
sub_filter 'src="/' 'src="';
# set types of files to 'sub-filter'
sub_filter_once off;
sub_filter_types text/html text/css text/javascript application/javascript;
...
- path: /<basePath>/?(.*)
