I’m using https://docs.docker.com/installation/centos/ as a guide to give Jenkins permissions to run docker commands. My server is CentOS 6.6. I created the group “docker” and added the user “jenkins” to it and restarted the docker service, but jenkins still fails with this error:
dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?
