podman-compose VS containerd

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

Containerd and nerdctl

Kubernetes on the backend used to utilize docker for much of its container runtime solutions. One of the modular features of Kubernetes is the ability to utilize a Container Runtime Interface or CRI. The problem was that Docker didn't really meet the spec properly and they had to maintain a shim to translate properly. Instead users could utilize the popular containerd or cri-o runtimes. These follow the Open Container Initiative or OCI's guidelines on container formats.

Container Engine: A runtime that executes and manages containers. Docker and containerd are popular container engines.

Multiple container runtimes are supported, like conatinerd, cri-o, or other CRI compliant runtimes.

This is a failed attempt to upstream part of containerd changes: https://github.com/containerd/containerd/pull/8789

Other part of containerd changes waits for gods-know-what: https://github.com/containerd/containerd/pull/9054

But I haven't gave up yet.

containerd is required by kubernetes to handle containers on its behalf. A big thanks to the HostAfrica blog for the information on setting containerd up for debain. So the containerd install will need to happen on both the WSL2 instance and the Raspberry Pis. For WSL2 you can just install containerd directly:

The context deadline exceeded: unknown is also in containerd, and is a known problem.

Docker Desktop adds a bunch of stuff to simplify local development and that’s why it has a larger memory footprint. You don’t use that when deploying but something like https://containerd.io/.
