• Dashboard: (local cluster - k8s)
• Dashboard (proxied):
  • Tunnel: ssh -L 18443:<DashboardIP>:443 k8s (discover DashboardIP as in instructions below)
  • https://localhost:18443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

Ubuntu:https://microk8s.io/#quick-start

snap install microk8s --classic

Start & Stop:

• microk8s.start
• microk8s.stop

Standard Services:

Tricks:

• Shell in pod:
  • kubectl get pods
  • kubectl get pod garden-7dd9f6bc88-pp87l
  • kubectl exec -it garden-7dd9f6bc88-pp87l – /bin/bash
    
• Discover dashboard IP:

  microk8s.kubectl get all --all-namespaces |grep kubernetes-dashboard | grep ClusterIP

• Discover dashboard token:

  microk8s.kubectl -n kube-system get secret
  microk8s.kubectl -n kube-system describe secret default-token-{xxxxx}

• ln -s /snap/bin/microk8s.docker /usr/local/bin/docker
• Install S2I from: https://github.com/openshift/source-to-image/releases

• Build docker image elsewhere and save/load into local k8s:
  • docker save mynewimage > mynewimage-docker.tar
  • Transfer file to microk8s server
  • microk8s.docker load < mynewimage-docker.tar

• Move a running container:
  • First, commit a snapshot to a new image: docker commit <containerId> mynewimage
  • Then, follow the load/save steps above
