Troubleshooting

If you get the following error:

`Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json: dial unix /var/run/docker.sock: connect: permission denied`

Open CLI for your Docker Container by running:

`docker exec -it <Container-ID> /bin/sh`

And see if you can replicate the error by running docker ps. If you see the error then run

`sudo chmod 777 /var/run/docker.sock`

in the container and use the password 'jenkins'. After this, try running docker ps again and it should work.
