Alpine for WSL with Docker

What you'll get

• Docker & Docker Compose (obviously).
• Non-root user supplied through build args.
• Non-root user is a member of admin and docker groups, as well as sudoers.
• While running this image with WSL, non-root user is used by default.
• Docker daemon starts automatically on non-root user login.
• Zscaler certificates. In case you're on corporate Windows machine, with Zscaler client running in the background.

Prerequisites

To build this image you'll need Docker, of course. No specific requirements regarding version as far as I know. Unless you want to use BuildKit for building, then it's 18.09 or higher.
To run the image WSL2 is required. Type wsl --status and check "Default Version".

Build WSL distro

Using Docker Build

source: https://medium.com/nerd-for-tech/create-your-own-wsl-distro-using-docker-226e8c9dbffe

docker build --build-arg USER=myuser --build-arg PASS=PassW0rd --tag alpine-docker-wsl .
docker run --name alpine-docker-wsl alpine-docker-wsl
docker export --output alpine-docker-wsl.tar.gz alpine-docker-wsl

Using BuildKit

DOCKER_BUILDKIT=1 docker build --build-arg USER=myuser --build-arg PASS=PassW0rd --output type=tar,dest=alpine-docker-wsl.tar.gz .

Run WSL distro

wsl --import alpine-docker-wsl .\alpine-docker-wsl .\alpine-docker-wsl.tar.gz
wsl --distribution alpine-docker-wsl
