docker desktop version 4.37.2 breaking docker-mac-net-connect?

[kmahelona]

I had this error, docker/for-mac#7520, and also noticed docker-mac-net-connect stopped working. When I tried the troubleshooting, the error I got was,

ERROR: (utun4) 2025/01/16 22:00:59 Failed to setup VM: failed to pull setup image: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Docker was running, but I assume these that docker mac issue is related to docker-mac-net-connect not working. Has anyone else experienced issues with 4.37.2?

The solution was to downgrade back to 4.37.1 and reinstall, restart, etc. until it worked again.

I just want to add that docker-mac-net-connect has been amazing for us for local development. Thank you for this package.

Hi @kmahelona

Possible solution:
I had a similar issue, and the main reason was that Docker Desktop stopped creating the Unix socket /var/run/docker.sock. Maybe you are facing the same problem. Here’s what you can do:

1. Check if the docker.sock exists: ls -al /var/run/docker.sock

Example output:

lrwxr-xr-x  1 root  daemon  38 Feb 20 12:34 /var/run/docker.sock -> /Users/gashpen/.docker/run/docker.sock

2. If /var/run/docker.sock is missing or points to an incorrect location, try the following:

• Open Docker Desktop Settings → Advanced.
• Toggle “Allow the default Docker socket to be used” off and on again.
• You will be asked to enter your password.
• After that, the socket should be created.

Hope this helps!
