Deprecate Localkube

[r2d4]

We are planning to deprecate the localkube bootstrapper in favor of the kubeadm bootstrapper. Please see and comment on this doc.

Deprecation Plan

• Run external-storage-provider as a pod
• Remove localkube from go-bindata
• Support the kubeadm bootstrapper with the none-driver
  • Decide if we still want to support non-systemd systems (complicates the configuration for the kubeadm kubelet)
• Switch bootstrapper flag default to localkube
• Stop upgrading localkube

• Update Dockerfiles to support kubeadm

Hi from one of the main kubeadm developers and an early localkube hacker 👋
So excited to see this happening!

LMK if you have any questions about kubeadm or what's going on there under the hood.
This resource might be helpful btw: https://github.com/kubernetes/kubeadm/blob/master/docs/design/design_v1.8.md

Look forward to have the new functional docs on how to update kubernetes in minikube.

Decide if we still want to support non-systemd systems (complicates the configuration for the kubeadm kubelet)

@r2d4 What's the final decision about supporting non-systemd systems?

I saw kubeadm is used by default in the last release, when is localkube gonna be deprecated/removed as a runtime? Thanks!

ping on the question, what is the deprecation timeframe here?

[dlorenc]

Ah, It's been removed here last week: #2911

I was using localkube to bootstrap my VM because the qinikube start --vm-driver=hyperkit fails on the latest Mac OS in versions after 0.26.0 or something like that. Now that this option has been removed, what should I use?

Thanks!

@parhamdoustdar - We should fix the issue you are encountering. Do you have one to cite?

As far as I know, most of issues where localkube helped was where there was a firewall/VPN blocking network connectivity. minikube does a poor job of detecting these issues, but we should be able to get you up and running without localkube.
