[TriLUG] docker vs podman

[Mauricio Tavares via TriLUG]

The list seems to be too quiet, so let me throw some gasoline-laden logs:

Podman as replacement of docker

Pros:
1. More secure (?) because it does not use a daemon and runs rootless
2. Docker does not support cgroup v2, which podman does
3. Docker has problems running in centos8. Podman comes installed in centos8.
4. Podman can run docker commands
5. Docker seems to have issues with firewalld
6. Fedora cheerleaders love podman

Cons:
1. No proper equivalent to docker-compose. podman-compose is not ready
for prime time and really is a way to convert compose files into
podman pods thingie
2. They would rather you use podman pods instead of docker compose,
but by then you are using kubernetes so why not just use kubernetes
and save the intermediate step?
3. Docker can run in rootless mode
https://docs.docker.com/engine/security/rootless/
4. Docker has better docs
5. Fedora cheerleaders love podman
