Question

How can I get an install of KubeApps running on K3s? What are the minimal required steps?

Answer 1

Installing k3s and kubeapps

1. Install k3s, (official instructions)

   curl -sfL https://get.k3s.io | sh -
   

2. Add KUBECONFIG for user. (Devops.StackExchange)

   export KUBECONFIG=~/.kube/config
   mkdir ~/.kube 2> /dev/null
   sudo k3s kubectl config view --raw > "$KUBECONFIG"
   chmod 600 "$KUBECONFIG"
   

3. Install Helm, (offical instructions)

   curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash
   

4. Setup Kubeapps, (official instructions)

   1. Install Kubeapps

      helm repo add bitnami https://charts.bitnami.com/bitnami
      helm repo update
      helm install -n kubeapps --create-namespace kubeapps bitnami/kubeapps
      

   2. Configure Kubeapps

      kubectl create --namespace default serviceaccount kubeapps-operator
      
      kubectl create clusterrolebinding kubeapps-operator --clusterrole=cluster-admin --serviceaccount=default:kubeapps-operator
      
      cat <<EOF | kubectl apply -f -
      apiVersion: v1
      kind: Secret
      metadata:
        name: kubeapps-operator-token
        namespace: default
        annotations:
          kubernetes.io/service-account.name: kubeapps-operator
      type: kubernetes.io/service-account-token
      EOF
      
      kubectl get --namespace default secret kubeapps-operator-token -o jsonpath='{.data.token}' -o go-template='{{.data.token | base64decode}}' && echo
      

   3. Play (note we have a slight modification with --address 0.0.0.0)

      kubectl port-forward -n kubeapps --address 0.0.0.0 svc/kubeapps 8080:80
