Microk8s up and running on Ubuntu 20.04

Install microk8s

sudo snap install microk8s --classic

Create some command line alias

snap alias microk8s.kubectl kubectl snap alias microk8s.helm3 helm snap alias microk8s.istioctl istioctl

OR

alias kubectl='microk8s kubectl' alias helm='microk8s helm3'

Update the .kube/config sudo microk8s config > ~/.kube/config

Enable microk8s add-ons

microk8s enable dashboard dns helm3 ingress metallb metrics-server prometheus registry storage

Get the microk8s kubernetes dashboard token

token=$(microk8s.kubectl -n kube-system get secret | grep default-token | cut -d " " -f1)
microk8s.kubectl -n kube-system describe secret $token

kubectl describe secrets -n ni-system kubernetes-dashboard-token-c2chm

Alternatively

Edit kubernetes dashboard to have the - --enable-skip-login set so the token is not required

kubectl edit deployment/kubernetes-dashboard --namespace=kube-system

and add enable-skip-login as below:

spec:
      containers:
      - args:
        - --auto-generate-certificates
        - --enable-skip-login
        image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1

Create kubernetes dashboard ingress

Now that we have the Kubernetes dashboard installed and we have the token ( or bypassed the need for the token ). Let's create a kubernetes ingress so we can access the dashboard. Create a ingress-dashboard.yaml yaml file

---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dashboard
  namespace: kube-system
  annotations:
    # use the shared ingress-nginx
    kubernetes.io/ingress.class: public
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/configuration-snippet: |
      rewrite ^(/dashboard)$ $1/ redirect;
spec:
  # https://kubernetes.io/docs/concepts/services-networking/ingress/
  # https://kubernetes.github.io/ingress-nginx/user-guide/tls/
  rules:
  - http:
      paths:
      - path: /dashboard(/|$)(.*)
        pathType: ImplementationSpecific
        backend:
          service:
            name: kubernetes-dashboard
            port:
              number: 443

Apply the dashboard ingress

kubectl apply -f ingress-dashboard.yaml

Access the kubernetes dashboard

You should now be able to access the dashboard by going to the microk8s server ip /dashboard

http://x.x.x.x/dashboard

At this point you should have a fully working microk8s install. Follow one of the other guide to install gitea ( git ), Prometheus ( monitoring ) or Linkerd ( service mesh )
