Make Jenkins run docker without sudo

Question

I would like to run Docker shell commands on Jenkins like:

docker ps

Is it possible to do it without using any plugins? Since Jenkins isn't a user, but a service account how can I add to the docker group?

Answer 1

First execute

sudo groupadd docker

Then execute

sudo usermod -aG docker $USER

Then log out its important to logout because your group membership is re-evaluated

Login and try again

docker ps
