Docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock

The user jenkins needs to be added to the group docker:

sudo usermod -a -G docker jenkins

Then restart Jenkins.


If you arrive to this question of stack overflow because you receive this message from docker, but you don’t use jenkins, most probably the error is the same: your unprivileged user does not belong to the docker group.

You can do:

sudo usermod -a -G docker [user]

Insert your user name where [user] is.

You can check it was successful by doing grep docker /etc/group and see something like this:


in one of the lines.

Then change your users group ID to docker:

newgrp docker

Finally, log out and log in again
