Ok, I was reading about Podman in bed last night.
It definitely has its advantages, especially when it comes to conserving resources.
It doesn't need a daemon in the background, which already taps resources and therefore offers a single point of attack. The containers start much faster than with Docker.
It will definitely be much better in use on smaller devices, like a Raspiblitz.
It was developed by Red Hat.
I'm already looking into it and may rename the Github project of mine to ‘haven-containerised’ and also make Podman available. But first I have to learn how to build it by default.
Docker is still used a lot on larger servers and is well integrated in some infrastructures.
I think which is ‘better’ is a personal decision, just like a musician decides which music software to use. However, there are advantages of Podman that can be utilised.
