docker
`/var/run/docker.sock` doesn't get generated on Docker Desktop startup
Description
I need to use the /var/run/docker.sock 3rd party socket. But event when the Allow the default Docker socket to be used (requires password) is already checked, the /var/run/docker.sock socket file does not exist.
To fix I have to:
- Uncheck
Allow the default Docker socket to be used (requires password) - Enter password
- Click Apply & Restart
- Check
Allow the default Docker socket to be used (requires password) - Enter password
- Click Apply & Restart
Then the expected /var/run/docker.sock will exist.
Reproduce
- Startup Docker Desktop
ls /var/run/docker.sock- Expected docker.sock does not exist
To fix I have to:
- Uncheck
Allow the default Docker socket to be used (requires password) - Enter password
- Click Apply & Restart
- Check
Allow the default Docker socket to be used (requires password) - Enter password
- Click Apply & Restart
Expected behavior
Allow the default Docker socket to be used (requires password) is already checked, the /var/run/docker.sock socket file exist.

EDITED:
On Mac, when docker is installed with less privileges the docker sock file is created under home directory, export DOCKER_HOST=unix:////Users/[USERNAME]/.docker/run/docker.sock
Docker desktop creates a .docker folder under the user home directory.
This is not a bug.
FINISHED EDITING
Issue see on Version 4.38.0 (181591).
On Settings>Advanced page we have a check box for "Allow the default Docker socket to be used (requires password)".
Once the user checks the above checkbox, the docker sock is created by docker desktop and all is well. Now for some reason, we restart docker desktop, then the settings page check box remains in checked state, but the sock file is missing. Then we have to follow steps give by xcollantesbelva to recreate the docker socket.
This most definitely is a bug, regardless of permission level, the fact that using those steps to uncheck and re-check a box to get the link established is by its nature a bug. It would be nice if this bug would get some attention as having to do this song and dance each and every time I restart my machine is getting extraordinarily old.
+1 This is still an issue. Despite the box being checked, I need to uncheck -> restart -> re-check -> restart and only then is docker.sock under /var/run
