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:

In a Windows Host
Without managing virtual machines (Docker Desktop + WSL 2 will do that for us)
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

A simple example of systemd timers. Inspired by this blog post.

1 - Go to /etc/systemd/system

2 - Create a FreeMemoryStatistics.service unit file like so:

[Unit]
Description=Logs free memory statistics to the systemd journal
Wants=FreeMemoryStatistics.timer

docker system prune --all --force --volumes

A guide on how to install Python 10 on WSL2 under Windows 10 / 11.

Install `pyenv`

pyenv is a tool that allows switching the global Python version, or choosing a specific version per project.

sudo apt update --yes
sudo apt install --yes build-essential curl git libbz2-dev liblzma-dev libffi-dev libncurses5-dev libncursesw5-dev libreadline-dev libssl-dev libsqlite3-dev llvm make python3-openssl tk-dev wget xz-utils zlib1g-dev
curl https://pyenv.run | bash
