Container shuts down immediately

[kingdomgardens]

Hi. I am not well versed with docker, so it may not be surprising that I couldn't get this to work. I am installing it on my synology nas using the container manager. About a year ago, I successfully installed the standard pi-hole in docker and have been using it, but I've wished for scheduled blocking and this seemed simpler than creating my own cron jobs, since I know little about that. When I start the container, however, it shuts down immediately. The log gives this error: "exec /s6-init: exec format error"
The closest I've come to decoding that is that it could indicate trying to run a 64 bit program on a 32 bit machine, but that doesn't seem like it would make sense here running on my ds920+ in docker. Any suggestions?

What's your run command

Thanks for the reply. Unfortunately I am too ignorant to know how to answer that question. I installed your lovely code from within the container manager on my synology nas, To start the container, I'm just clicking the start button in the container manager. It doesn't tell me what command it's actually using. I don't see that info in the logs that it generates on its own. Can you tell me how to find out what the run command is?
