A docker, when run for the 1st time, won't do so:

$ docker-compose -f docker-compose.local.yml up -d

permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json?all=1&filters=%7B%22label%22%3A%7B%22com.docker.compose.config-hash%22%3Atrue%2C%22com.docker.compose.project%3Doxygen%22%3Atrue%7D%7D": dial unix /var/run/docker.sock: connect: permission denied

I'll run this command

$ sudo setfacl --modify user:user1:rw /var/run/docker.sock

which will resolve the issue. However, after a reboot, the issue will arise again.

Why? How to make the change permanent?

Because that file is created by the docker.socket service when the service starts and removed when it stops or reboots.

Changing the acl on system files is the wrong way.

Either put your user in the correct group or run docker in rootless mode.

Edit: docker should be the correct group.
