i have the problem that the acme.sh container does not show logs (docker-compose logs acme.sh), to fix this i changed the crond parameters.
/ # crond --help
BusyBox v1.30.1 (2019-06-12 17:51:55 UTC) multi-call binary.
Usage: crond -fbS -l N -d N -L LOGFILE -c DIR
-f Foreground
-b Background (default)
-S Log to syslog (default)
-l N Set log level. Most verbose 0, default 8
-d N Set log level, log to stderr
-L FILE Log to FILE
-c DIR Cron dir. Default:/var/spool/cron/crontabs
* `acme.sh`'s `ssh.sh` is probably one of the hooks that's most versatile
* By default, it's not installed on `alpine` docker images and therefore is lacking in the `acme.sh` docker image
* This change adds the `openssh` package and therefore the `ssh` and associated commands
