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

Question

I am new to docker. I just tried to use docker in my local machine(Ubuntu 16.04) with Jenkins.

I configured a new job with below pipeline script.

Answer 1

In addition to adding the user to the docker group and trying everything mentioned in this thread, it took me a while to realize that I had to restart my terminal and then log back into the ec2 instance. It worked after that.
