tried building it, saw no errors: docker build -t obsidian .

I've cobbled this together and am unsure about many things, but I can't make any progress since I get:

...

[supervisor  ] service 'app' exited, shutting down... 
...

I tried running it like this: docker run --rm -p 5809:8089 -e USER_ID=1000 -e GROUP_ID=1000 --name obsidian obsidian

startapp.sh

#!/bin/sh                                                                                                                                            
exec /opt/obsidian.AppImage --no-sandbox --disable-dev-shm-usage --disable-gpu --disable-software-rasterizer

btw. on my first tries, startapp.sh had a chmod 770 applied to it and I got this error:

[supervisor  ] starting service 'app'...

[supervisor  ] all services started

After a chmod +x applied to it, I am now getting: /bin/sh: can't open '/startapp.sh': Permission denied

Looking for some tips on what I am doing wrong ehre.

[jlesage]

The obsidian.AppImage binary is using glibc instead of musl, which is what Alpine uses. You can try to install libc6-compat or gcompat to see if it's working better. Other solutions are to build the binary yourself from sources, or use a ubuntu/debian baseimage.

Thanks, I'll try your advice but still, do you have any idea what's going on here with the ownership and permissions of startapp.sh?

[jlesage]

In your source tree, a chmod 755 of startapp.sh should do the job.

If permissions on the file are good, you won't get the error /!\ No application to start: /startapp.sh is missing or not executable. /!\.

Other Permission denied related errors are related to the executable startapp.sh tries to execute.

This solved a problem for me upgrading from Ubuntu-20.04 v3 to v4, thanks!
