  * 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/]]

====== Installation & Configuration ======
**Ubuntu:**[[https://microk8s.io/#quick-start]]<code>snap install microk8s --classic</code>

    * ''kubectl exec -it garden-7dd9f6bc88-pp87l -- /bin/bash'' \\ 
  * Discover dashboard IP:<code>microk8s.kubectl get all --all-namespaces |grep kubernetes-dashboard | grep ClusterIP</code>
  * Discover dashboard token:<code>
microk8s.kubectl -n kube-system get secret
microk8s.kubectl -n kube-system describe secret default-token-{xxxxx}
</code>
  * ''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
