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
