This is a really helpful explanation - thank you!

Regarding Docker Desktop on Linux - yeah definitely not strictly necessary. Sometimes it’s just convenient to have a UI instead of fumbling around trying to remember some cli incantation to check for dangling volumes or what-have-you. I think ideally I want to move to Podman anyways - but I’m using pop_os as my dev distro at the moment and am stuck on an older version which doesn’t have their native `podman compose` implementation yet
