docker - acme.sh command only causes load

[master-kw]

Hi,

I'm running acme.sh as a docker container on my Synology NAS. If I only start a terminal command acme.sh or acme.sh --help, the cursor is blinking and nothing happens. After a few seconds CPU and Memory load runs up until the Diskstation freezes.

Installed via task planer:

• docker run -d --name acme.sh \
• -v /volume1/docker/acme:/acme.sh \
• --net=host \
• --restart always \
• neilpang/acme.sh:latest daemon

What I found out:

If I remove the volume enviroment it work's. I've checked all required ownerships, they're correct. In terminal I can check nslookup, dns settings, cc., but no acme.sh.

Connecting via ssh terminal@root with docker run --rm -it neilpang/acme.sh /bin/sh, I get a prompt and commands are working (bridge mode, no volumes). Even there, set a volume /docker/acme:/acme.sh leads to the same result.

I stuck since an announced update inside docker to version 3.0.8. Register a new container with separated versions down to 3.0.0 were not successful.

Further informations:

• Synology Diskstation DS716+II
• DSM 7.2.1-69057 Update 4
• Docker version 20.10.23, build 876964a
• Linux Diskstation 3.10.108 #69057
• acme.sh 3.0.8

Any ideas?

Regards,
Oliver

You objective of running acme.sh is unclear. Are you trying to get a cert for the NAS or something else? As I understand it acme.sh is not a standalone application, it is a utility that needs to be pointed at a solution.

Check out Synology DSM 7 with Let’s Encrypt and DNS Challenge for an implementation concept on the NAS.

I have completely lost sight of the issue and have now solved the certificate via docker@RasPi and nginx ProxyManager.
