[cetic/nifi] Access Unknown: Certificate and Token not found.

Sms-Rk commented 1 year ago

Describe the problem hi i installed nifi and zookeeper on kubernetes cluster rke using helm and im using nginx ingress controller i can access web ui over https using ingress from outside the cluster but when i enter username and password i get Access Unknown: Certificate and Token not found.

Version of Helm, Kubernetes and the Nifi chart: helm version 3.7 , latest image of nifi ,

this is my values.yaml

  #
  # To use a storage class that already exists on the Kubernetes cluster, we can simply reference it by name.

thanks for you help

We are facing exactly the same issue. We are on GKE and single user authentication doesn't work with nginx ingress. If I do a kubectl port-forward on the service I can auth on localhost:8443 but not on a custom domain. I try several things on nginx ingress annotations without results

did you find any way to solve the issue?

banzo commented 1 year ago

The chart currently supports NiFi 1.16, not "latest" afaik.

You can try if #294 fixes the issue, it adds support for 1.20.

I had this same issue, but the nginx configuration mentioned here made it work for me:

https://github.com/cetic/helm-nifi/issues/273#issuecomment-1471953019

kobethuwis commented 7 months ago

@Sms-Rk I had some troubles with setting up the ingress-nginx-controller with NiFi as well. I remember I got this error, but don't remember why & when exactly 😄

These are some things I had to fix:

x ingress-nginx-controller was running ingressing on the same port as I was serving nifi (8443); so I changed my NiFi serving port to 9443:

properties:
  httpsPort: 9443
service:
  httpsPort: 9443

x My ingress resource wasn't configured correctly for NiFi, so I added the following annotations:

properties:
  webProxyHost: "${var.host_nifi}"

ingress:
  enabled: true
  hosts:
    - ${var.host_nifi}
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"

Hope this helps 😅
