The following does NOT need to connect the server, which is another way, where the server provides a secret via http, and the letsencrypt server checks it. But the drawback of that is that you need to run the webserver and later reconfigure it, since this is only needed for the initial cert afaik. So I went the other way. Will see how the renewal works, but I think it should work.

If you are running out of disk space on your docker host, you can free up some space by removing unused docker images, containers, and volumes. I am running docker-compose and always watch the logs, since the service is not high scale yet, so the log files fill up. This means from time to time I need to free some disk space.
