@jriou Indeed I migrated on a rainy weekend !

The main issued I got was: User Namespaces, Network and obviously DNS.
This blog help me understand the the difference with #docker behaviour by setting up some demo apps:

To experiment the #rootless mode: I followed: https://www.redhat.com/en/blog/rootless-podman-user-namespace-modes

How to install multi-container applications with Podman quadlets

Quadlet files make it easy to manage applications that need multiple containers, without needing root privileges

Giacomo Coletto

I'm still configuring my #alpinelinux + #cosmic desktop, and I realize I didn't want to install git in the main user-land on that computer, I'm being extra paranoid - and kind of petty. So I did whatever sane person would do:

- install #podman
- configure podman to be #rootless
- install #crun because rootless is not exactly what I really want
- install #toolbx
- install #git inside that isolated container
- profit

You might have noticed that I have spend some time in my Quadlets Repo, taking care of some Grafana stuff.

Took me a bit to understand it but I’m quite happy with the result.

Check it out if you’d like to deploy your Grafana instance with a few extras in your homelab!

Containers are an essential skill for every Sysadmin. Red Hat's Podman makes this easy and secure with rootless Containers. But a normal container or Compose needs to be started manually, Quadlets change that. Use my presents and convert them into SystemD Services with the Wiki Page I wrote.

Thanks for that hint, @jwildeboer! Immich is up and running - import of my families libraries will take a while though… #Immich #Podman #rootless #SelfHosting

Talk almost ready – Chemnitz Linux Days, here we go! 💻🐧

Putting the final touches on my talk – tomorrow it’s time. ⏰

Chemnitz Linux Days 2026, I’m all set and excited to be there. 🙉

30+ slides on Podman in rootless mode in combination with Quadlets are ready – even though this topic really only scratches the surface. 📚

I'm still experimenting with #podman #rootless and can't find how to allow containers/pod to access #localhost

Context: one pod with 2 #containers, one needs access to localhost. Podman is 5.4 with pasta networking.
I tried adding "-T" or "host-gateway" options to pasta network on the pod but still no way.
Can't to find a single complete article on how to manage networking on pods, a lot of different information

Has anyone a solution to this problem? Is it simply possible?

#sysadmin #linux

Some years ago, I started using #Docker #rootless for my #selfhosting needs. I was quite happy with it, even if finding information about rootless mode has been quite difficult.
I mostly used #compose setups.

Some days ago, I looked at #podman to replace those setups with a more modern stack. Podman works well for single containers but not that much podman-compose: don't believe the articles telling you that it's automatic, it's not!

#containers #apps #linux #floss

I didn't expect #rootless #podman to be such a rabbit hole nightmare.

It appears to be impossible to get the permissions right for a mounted folder for which the user starting the container has reading rights on the host via being in the group the files belong to.

I thought that is just a very basic use case. Probably I will just use docker again.

Tried to decide if I should look into #pasta instead of #slirp4netns. Looked at their webpage and found a long list of features. Nice.

Looked for a man page for the pasta command, but it was nowhere to be found on the webpage. Instead I could watch a 10 minutes long video showing 3 terminal windows and a window with a scrolling text explaining what happens in the terminal windows.

That is a thanks, but no thanks from me.
