acme.sh: Restart server in docker not working

Question

I use acme.sh to install a SSL-certificate to a nginx-server, which runs in a docker-container. This worked fine.

I now want to make a cronjob to regularly check and perhaps renew the certificate. This is what I tried:

0 0 * * * sh $MYHOMEDIR/.acme.sh/acme.sh --cron --home $MYHOMEDIR/.acme.sh --reloadcmd "docker compose -f $MYHOME_DIR/docker/my-app/docker-compose.yaml restart"

This is renewing the certificate when needed, but it's not restarting the container.

I found somewhere that --cron doesn't work with reloadcmd, so I tried:

0 0 * * * sh $MYHOMEDIR/.acme.sh/acme.sh --cron --home $MYHOMEDIR/.acme.sh --renew-hook "docker compose -f $MYHOME_DIR/docker/my-app/docker-compose.yaml restart"

But with the same result: The certificate is renewed, but the container is not restarted.

Any ideas?

Most likely cron does not run inside your container, but from the amount of info you provided, it is very hard to figure out. Dockerfile? docker-compose.yml (or the exact command you used to start your container)?
