Shameless self-plug here. I wrote a blog post to document my methodology after having some issues with publicly available examples of using Podman and traefik in a best-practices config. Hopefully this finds the one other person that was in my shoes and helps them out. Super happy for feedback if others care to share.
What’s the advantage of socket activation? Is it more secure than exposing a docker port?
Great question. I tried to very briefly touch on it in the post. The bottom line is that its benefits are there mostly for rootless podman, which I’ve chosen not to implement here (yet). You can also configure it so that the socket is always active and that will then trigger the service associated with it, so that you save on resources when the service isn’t needed. However, I didn’t want to do that as it would likely increase page load time for readers.
