Builds/Builders inside WSL2 are not showing in Docker Desktop for Windows

[mlalpho]

Description

I was checking out the new feature: Explore Builds

Builds/builders created/running inside the WSL distro are not showing in Docker Desktop.

I'm running Docker Desktop for Windows with WSL2 integration -- Docker Desktop 4.30.0 (149282)

Please let me know if you need any more info/testing.

Thank You!

Reproduce

In CMD:

1. docker buildx create --name container-builder-local --driver-opt=image=moby/buildkit:latest
2. docker buildx bake --builder=container-builder-local docker-compose.yml

Builder/Builds show when invoked from CMD ☝️

In WSL2:

1. docker buildx create --name container-builder-wsl --driver-opt=image=moby/buildkit:latest
2. docker buildx bake --builder=container-builder-wsl docker-compose.yml

Expected behavior

Builder and build history/active builds should be visible whether building on local windows command line or WSL2 distro

Thanks for reporting!

This is a known issue. Atm Docker Desktop runs backend services on the host machine, and for Windows users it means that Docker config on WSL is not taken into account. For the Builds view this is problematic as a user might not want to invoke build commands on Windows but WSL and therefore created builders will not be shown (Buildx configuration is stored in ~/.docker/buildx).

As a workaround what you can do is creating the builder on WSL2:

$ docker buildx create --name mybuilder

And create another one with Powershell/CMD on Windows host with the same name:

> docker buildx create --name mybuilder

This way the backend service will monitor the container builder within the Buildx store on Windows host that would match the one used on WSL.
