Support microk8s

[bkcsfi]

Will tilt work on microk8s? I'm on a spotty internet connection, haven't been able to git clone the example tilt app to try tilt via KUBECONFIG env var.

I did try this, which didn't work likely because the context is not recognized...

$ tilt demo
tilt demo mode only supports Docker For Mac or Minikube
check your current cluster with:

kubectl config get-contexts

$ microk8s.kubectl config current-context
microk8s

I had setup KUBECONFIG env this way:

$ microk8s.kubectl config view --raw > ~/.kube/config
$ set -x KUBECONFIG ~/.kube/config   # fish shell

Short answer: yes! Tilt will work with microk8s

Longer answer: There's two separable questions with slightly different answers: "will Tilt work with microk8s?" and "will tilt demo work with microk8s?"

You can tilt up against any cluster! It doesn't matter if the cluster is local or remote. MicroK8s will work fine. But to run tilt up against microk8s, you need read/write access to the container image registry that you're building images for, so that microk8s can pull the images.

But most of the tilt demos and tutorials use our container registry. We don't give everyone on the internet write access to that (for obvious reasons).

So when you run tilt demo, we recommend you use Docker For Mac and Minikube. These clusters let you talk directly to the in-cluster docker server, so you don't need to upload/download things from the registry:

AFAIK it's possible to do this with MicroK8s. We just haven't added support for it yet:
https://github.com/ubuntu/microk8s/blob/master/docs/registry.md
but it should be easy for us to add. Stay tuned!
