Kubernetes on Docker on Linux on Windows

Kubernetes on Docker on Linux on Windows

This guide shows how to run Kubernetes in a Windows Host, using kind to run the control plane in Docker and WSL 2 to run Docker itself.

The whole point of doing that is to run Kubernetes:

  1. In a Windows Host
  2. Without managing virtual machines (Docker Desktop + WSL 2 will do that for us)
  3. Without using Docker Desktop's native Kubernetes feature (as it has a tendency to break workflows that do not relly on K8s).

Sync a fork with upstream

Run the following (note: use main/master as needed):

git fetch upstream
git checkout master
git merge upstream/master
git push origin master
