Kubernetes dashboard ingress HTTP error 400

Question

Installed Kubernetes dashboard with Helm

helm install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard -f values.yaml --create-namespace -n kubernetes-dashboard 

ingress: enabled: true paths: - / hosts: - kubedash.labs.example.com annotations: kubernetes.io/ingress.class: nginx nginx.ingress.kubernetes.io/backend-protocol: HTTPS tls: - secretName: ca-wildcard-example-cert-secret hosts: - kubedash.labs.example.com metricsScraper: enabled: true metrics-server: enabled: true protocolHttp: true ## Additional container arguments ## extraArgs: # - --enable-skip-login - --enable-insecure-login # - --system-banner="Welcome to Kubernetes" 

Kuberetes dashboard ingress returns

curl -I https://kubedash.labs.example.com HTTP/1.1 400 Bad Request Server: nginx/1.21.6 Date: Wed, 03 Aug 2022 18:39:17 GMT Connection: keep-alive 

Nginx ingress version 2.3.0 installed via Helm.

Any help would be much appreciated.

Answer 1

Adding --enable-insecure-login made it to work on HTTPS via ingress, its kinda insecure but do the trick

whole config :

ingress: enabled: true paths: - / hosts: - kubedash.labs.example.com annotations: kubernetes.io/ingress.class: nginx nginx.ingress.kubernetes.io/backend-protocol: HTTPS tls: - secretName: ca-wildcard-example-cert-secret hosts: - kubedash.labs.example.com metricsScraper: enabled: true metrics-server: enabled: true protocolHttp: true ## Additional container arguments ## extraArgs: # - --enable-skip-login - --enable-insecure-login # - --system-banner="Welcome to Kubernetes"
