Docker not found in Jenkins running locally in VM (not as a docker image)

Question

I am having trouble building from a public repo, installed Jenkins locally as a service add all the docker pipeline plugin but when I try to build I get this Error

 > git rev-list --no-walk d639281fcf8f6e5dab1cd633a0f7af0727ff7dc5 # timeout=10

I am assuming that Jenkins is unable to run docker because it requires admin privileges in my vm (because I use sudo with every docker command)

How do you grant Jenkins permission to run docker commands as if I was using docker with sudo

Answer 1

I think you should add jenkins user into docker group.

First execute

sudo groupadd docker

Then execute

sudo usermod -aG docker $USER
