Docker Desktop 2 not Creating Unix Socket on Alpine WSL 2

[AlexanderAllen]

• I have tried with the latest version of my channel (Stable, 2.2.0.0 42247)
• I have uploaded Diagnostics
• Diagnostics ID:

Expected behavior

• After enabling WSL integration for Alpine WSL (version 2),
• Docker Desktop should mount unix socket for communication with Docker Engine.

Actual behavior

docker info
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Information

• Windows Version: Windows 10 Pro Insider Preview, version 2004, build 19551.1005
• Docker Desktop Version: Stable, 2.2.0.0 42247
• Running Windows natively.

PS C:\Users\user> wsl -l -v
  NAME                   STATE           VERSION
* Alpine                 Running         2
  Ubuntu-18.04           Running         2
  docker-desktop         Running         2
  docker-desktop-data    Running         2

Steps to reproduce the behavior

1. wsl -d Alpine
2. docker info

lxcore_service.etl.txt
lxcore_user.etl.txt

• What does enabling the WSL 2 in Docker Desktop entail?
• Is toggling the integration enable the Unix socket for communication with the Docker Daemon?
• Is integration (and the unix socket) currently available on Ubuntu WSL?
• Could it be that Alpine is missing additional packages for integration to work?

The proxy (as well as CLI binaries that we ship with docker-desktop) depends on glibc. You need to install a glibc package (such as https://github.com/sgerrand/alpine-pkg-glibc) on your alpine environment to make it work.

You've made my day @simonferquel . Tested, confirmed working. I wrote this morning a story detailing the install and successful test. I can't be thankful enough to your team for the WSL integration, it's magical.

Closed!

Any chance that /mnt/wsl/docker-desktop/docker-desktop-proxy can become available as a uclibc binary or a static binary with no dynlib dependencies?

Just a note, sudo ln -sf /mnt/wsl/docker-desktop/shared-sockets/guest-services/docker.sock /var/run/docker.sock worked for me :) But yeah, that would be great to make this automatically

[rigon]

@thunder-spb It also works for me!
