@Romain This is the print out of ps aux | grep -i vscode (I just screenshot the process of my userid): System Info: Ubuntu 16.04.6 LTS; vscode version: Version: 1.60.0-insider (Universal) Commit: 699084fdb48460c68086b85b5c08f3d39055e772; vscode Docker extension version: v1.15.0

Answer 1

I am struggling with this problem too with Docker Desktop for Mac Intel Chipset.

The error is because docker.sock location for Docker Desktop default is /Users/<user>/.docker/run/docker.sock and some third party use /var/run/docker.sock as default.

You can make sure by manually creating symlink using this command:

sudo ln -s -f /Users/<user>/.docker/run/docker.sock /var/run/docker.sock

You can automatically create symlink from Docker Desktop setting. Allow the default Docker socket to be used (requires password)
