I have a Minio ClusterIP service running in a Kubernetes cluster. And on top of it, I have a NGINX Ingress Controller. NGINX Ingress needs to forward Minio traffic to the Minio service, and other traffic to their corresponding services.
My Ingress configuration looks like this:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- http:
paths:
- path: /app/?(.*)
backend:
serviceName: app-service
servicePort: 3000
- path: /minio/?(.*)
backend:
serviceName: minio-service
servicePort: 9000
Once deployed, the app works fine. However, the Minio page has problem, complaining:
This page isn’t working
example.mysite.com redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS
And indeed, the requests are kept redirecting. Here is the screenshot from Chrome DevTools' Network console.
Any ideas?
As Minio always redirects to /minio/, you need to keep /minio
in the path and pass it on to the Minio service.
When I change its path rule to - path: /(minio/.*)
, it works. Now the Ingress configuration looks like below:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- http:
paths:
- path: /app/?(.*)
backend:
serviceName: app-service
servicePort: 3000
- path: /(minio/.*)
backend:
serviceName: minio-service
servicePort: 9000
And I've got the Minio service working in the browser:
Hope it is helpful.
