i just ended up going with a new image with the components installed, which i’ve been informed is best practice.

Hey there!

i have an Owncast container that needs two extra files added to it every time it starts up because the base image doesn’t include them. they can be downloaded from within the container. i just need a way to tell the container to always do that when it starts up.

i’ve tried adding this to my quadlet:

[Container]

Exec=apk update && apk add --no-cache mesa-va-gallium mesa-dri-gallium

but it doesn’t work.

does anyone know how to correctly automate this?

thanks!

I think you can use volumes or mounts to add signal files.

well, we can download these libraries from within the container. i just want a way to tell the container to always do that on startup

Well, ithe correct way would be to create a new container image using your current image as the base and executing your commands, you then need to rebuild that image when the base image is updated.

do the logs show any errors with the exec?

What about putting it in a simple shell script with a volume mount?
Or maybe something like this would work? Exec=sh -c “apk update && apk add --no-cache mesa-va-gallium mesa-dri-gallium”

Sorry, I’m pretty new to quadlets myself, but I’ve gotten stuff working thanks to the podman documentation.
