Is the kubernetes-dashboard compatible with k3s?

[senpro-ingwersenk]

Hello!

I have a few not-so-terminal-savy people in my company that would also like to see what the Kubernetes cluster is doing - so I found this: https://artifacthub.io/packages/helm/k8s-dashboard/kubernetes-dashboard?modal=values

Most of it should be fine, but since k3s uses Traefik by default for it's ingress, I would like to know if that can still be made working?

I am still relatively new to Kubernetes; now that I understand most of what we have here and how to deploy stuff, I want to expand my knowledge with helm charts - and this seems like a pretty good example.

As far as I understand, I will at least need this:

apiVersion: v1
kind: Namespace
metadata:
  name: k8s-dashboard
---
apiVersion: helm.cattle.io/v1
kind: HelmChart
metadata:
  name: k8s-dashboard
  namespace: kube-system
spec:
  repo: https://kubernetes.github.io/dashboard
  chart: kubernetes-dashboard/kubernetes-dashboard 
  targetNamespace: k8s-dashboard
  valuesContent: |-
    # Values here...

But do I also need to add an IngressRoute (apiVersion: traefik.containo.us/v1alpha1) or can I just configure that through the values itself? We mainly use those to set quick connectors like this:

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: someservice
  namespace: insomenamespace
spec:
  entryPoints:
    - websecure
  routes:
    - kind: Rule
      match: Host(`someservice.our.domain`)
      services:
        - name: someservice
          port: 80

Thanks!

It should work fine. The dashboard chart has seen some changes recently that make it quite bloated, if I remember correctly it now tries to bundle subcharts for both cert-manager and ingress-nginx. You'll probably want to figure out how to disable or configure those.

[senpro-ingwersenk]

Yep... It's values are absurdly exhaustive. It's actually a little "scary" for a newcomer. But, you can disable those things, even including the metrics-server and metrics-scraper.

It exports a couple of services (api, web, auth) so I guess I will just have to scour the templates and add the Traefik routes... Too bad there isn't a standart ingress kind that universally works across nginx and traefik.

The standard Kubernetes Ingress type should work for all ingress controllers.
