Question for the experienced SREs: does it still make sense to learn docker instead of podman in 2023?

I’m a relatively newly minted SRE and the eli5 explanation that I’ve gotten is that podman allows rootless containers and the only real disadvantage is that it lacks an equivalent version of ‘docker-compose’.

I understand that we ought to be using the right tool for the right job but to be frank there is only so many hours in a day for learning everything.

Also for the OP: thanks! I have an O’Reilly subscription so I’m covered but I’m sure there are folks who can use this book.
