rootlesskit VS podman-compose

The official docs list some known limitations of rootless Docker, and says that "Host network (docker run --net=host) is also namespaced inside RootlessKit." I don't understand how RootlessKit works, but I am wondering if this means that rootless Docker containers are unable to connect to ports on the host? I also checked the RootlessKit docs but I'm out of my depth there: (https://github.com/rootless-containers/rootlesskit/blob/master/docs/network.md).

Fair Warning: If your app needs to be able to see the user's IP (for throttling, banning, etc.)

Rootless Docker doesn't properly support IPv6 yet with the ability to see the end-users source IP.

There may be some overhead with networking if your application uses a very large amount of bandwidth. See:

https://github.com/rootless-containers/rootlesskit/tree/v0.1...

Otherwise for general dockerized applications, you won't notice any difference.

You may find some quirks, but these can all be worked around easily as described on the rootless docker page.

We run it in production with no issues so far.

Now with Fedora 34 I'm having issues from rootlesskit not being packaged. Got the binaries from https://github.com/rootless-containers/rootlesskit/#setup since that go get command never works. I have installed over 50 packages using go get but rootlesskit ALWAYS fails to compile because of some dependency like google/uuid and different Go versions.

Podman (via podman-compose),

Source code for the feature is here if you care to inspect it:

https://github.com/containers/podman-compose/blob/bce40c2db3...

Admittedly, I'm still on podman 4.3.1, but I dont' see any reason why this would stop working in later versions of podman.

Can someone link me to what Compose means in this context? Google takes me to https://github.com/containers/podman-compose but I just wanna make sure that's what they are talking about.

🛑 Docker Desktop is free for personal use but requires a paid subscription for enterprises. A free open source alternative is Podman and Podman Compose which uses the same core syntax as the Docker tools and can be used as a near drop-in replacement.

I’m dumb. When I wrote the article it was late. Docker-Compose really was a game changer.

Yea Podman compose exists. I’ll add a section about docker compose to it in an update.

From googling this error I've come across a few different threads but I haven't gained any success. Firstly I found this github thread which doesn't reference my error but still seems related. I followed the "sudo podman-compose systemd --action create-unit" and "podman-compose systemd -a register -f myfile.yml" minus the -f flag as it wouldnt run with that. This indeed created a [email protected] file, but its created in the /etc/systemd/user directory rather than /etc/systemd/system which raises an issue as I'm having to run these two containers as root. I try registering the podman-compose@torrent but I'm told the service doesnt exist. Running it as user I'm told it failed to connect to bus: no medium found. So I basically reached a dead end there.

Have a look at Podman Compose

You can also use podman-compose for the orchestration https://github.com/containers/podman-compose
