Troubleshooting

If you get the error relating to the Docker daemon not running in the background, then you have probably just installed docker just recently. You'll need to run dockerd in another terminal. Alternatively, you can restart you computer so the daemon will begin running.

If you get the error: Error starting userland proxy: listen tcp 0.0.0.0:XXXX: bind: address already in use, then you'll need to kill process using that port. Find the process id using the port XXXX and kill it with the commands:

lsof -nP +c 15 | grep LISTEN
kill -9 (process_id)
