Hi Erwin,

You’d definitely want to have your own e-mail address there for the ACME_EMAIL. Just replace the noreply[at]example[dot]com with the e-mail address you’d like to use. That alone shouldn’t be causing the container to crash though. Unfortunately, the error code 1 is a ‘catch-all’ code and does not provide much insight.

A couple other things that I can think of are:
01: See if you’re able to capture the logs from any of these commands before the container crashes:
docker logs -f
docker service logs

02. Your socket-proxy could be causing you issues. While note ideal, try this yml instead and see if that does the trick.

Hopefully one of these helps!
