Docker under WSL1 without Docker Desktop is not possible, so I'm trying to run Docker from within WSL2 Alpine by following this article.
However I'm not that lucky to get it working. Fully log included below.
Anyone know where thing went wrong please?
The whole thing is done under alpine/v3.15 (installed from https://apps.microsoft.com/store/detail/alpine-wsl/9P804CRF0395?hl=en-us&gl=US) --

CodePudding user response：
You could just run the Docker daemon as noted in the blog post you linked to:
sudo dockerd
Then switch to another WSL Alpine instance and run the Docker client commands.
But to use the OpenRC Docker service, you have two options.
First, you can start OpenRC and then start the Docker service manually:
openrc default
rc-service docker start # or service docker start
Or you can add the Docker service to the default runlevel (one-time), and then it will run whenever OpenRC is started in that runlevel:
One-time:
rc-update add docker default
Then, to start OpenRC with the default runlevel, which will also run Docker:
openrc default
Really, it seems the only thing you were missing is that OpenRC wasn't initialized first. Normally, that would be done during Alpine init, but WSL's own /init is running instead.
