In our Kubernetes Cluster we have a micro frontend, which is accessable under image-self-service:8080 without any additional path. To be able to use it in a bigger application I want to use an Nginx-Ingress to reroute from url-to-site/profile to image-self-service:8080/.
I have found and read this SO post, thats basically asking the same thing: Remove routing path from Kubernetes ingress and the linked documentation here: https://github.com/kubernetes/ingress-nginx/blob/main/docs/examples/rewrite/README.md
which resulted in me using a .yaml for my Ingress that looks like this: (sensitive Information removed)
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/proxy-body-size: "50m"
traefik.ingress.kubernetes.io/router.entrypoints: websecure
traefik.ingress.kubernetes.io/router.tls: "true"
nginx.ingress.kubernetes.io/enable-cors: "true"
nginx.ingress.kubernetes.io/cors-allow-origin: "*"
nginx.ingress.kubernetes.io/cors-allow-methods: "PUT, GET, POST, OPTIONS, DELETE"
nginx.ingress.kubernetes.io/cors-allow-headers: "DNT,X-CustomHeader,X-LANG,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,X-Api-Key,X-Device-Id,Access-Control-Allow-Origin"
nginx.ingress.kubernetes.io/rewrite-target: /
name: intranet-backend-ingress
namespace: intranet
spec:
rules:
- host: xxx-test.xxx.xxx
http:
paths:
- backend:
service:
name: image-self-service
port:
number: 8080
path: /profile(/|$)(.*)
pathType: Prefix
- backend:
service:
name: intranet-ui
port:
number: 8080
path: /
pathType: Prefix
...
For readability I also removed other endpoints which are more specific as I don't think those interfere.
I have tried using nginx.ingress.kubernetes.io/rewrite-target: / and nginx.ingress.kubernetes.io/rewrite-target: /$2
If I remove the rewrite-target and add a specific path, the forwarding works but with the additional path, so it results in a 404 from the underlying webservice. The Response I get using the rewriting is simply: 404 page not found which I believe to be an Ingress message.
