nerdctl VS Podman Desktop

Direct use of containerd? containerd? turns out I didn't know anything about container technology. containerd was originally developed by Docker in 2015 as a daemon that provided basic container management capabilities under Docker. containerd's scope has gradually expanded and now seems to cover almost everything in the Docker Engine. For example, nerdctl is a CLI for containerd; the UX is almost identical to the Docker CLI, and Docker Compose is also supported (nerdctl compose).

Nerdctl[1] (for containerd) works fine with docker-compose.yml for my purposes (which are not much). The only issue I encountered was with environment variable substitution not working the same as docker-compose, but I didn't look hard for a solution and edited my compose file

1. https://github.com/containerd/nerdctl mine came bundled with Rancher desktop, and 'nerdctl compose up' is all I've needed

I haven't tried it personally but you might be able to export the tar from docker host with docker cli and then load it on containerd host using nerdctl - https://github.com/containerd/nerdctl

It looks like the real nice thing here is having a formula for QEMU with the ARM patch applied: https://github.com/simnalamburt/qemu/tree/hvf

With this I believe you could also used [nerd](https://github.com/containerd/nerdctl) instead of podman but I haven't tested it yet.

One area, where containerd didn't had a first class support was CLI. the default containerd CLI "ctr" has a very naive implementation. The reason for that I believe is, containerd as a system was never meant to be consumed by humans, and was designed to be consumed by higher layers e.g. orchestration systems like nomad or k8s. However, with the deprecation of dockershim in k8s, and users moving to containerd, a new docker compatible CLI came out:

If you just have containerd running on your system (with no docker daemon running), you can just install nerdctl and add

alias docker="nerdctl"

to your ~/.bashrc file.

Then you can just run any docker commands the way you used to with docker, and it will run those commands against the containerd API giving you the same CLI experience that you used to have with docker.

A new, search-driven command palette is now available to enable quick access to various commands available across 🦭 Podman Desktop. You can try this new tool out by hitting the F1 key. #4081 && #3979

Please share this experience and what went wrong with the postman team. It is the only way things can improve.

You don’t have to solve the problem. Just state your problem. If you need inspiration, here is an example: https://github.com/containers/podman-desktop/issues/868

I wanted to try a while ago so I downloaded Podman Desktop, but I couldn't get past the initial setup due to issues in the desktop app. I was able to reproduce this on two or three Macs, can't recall exactly.

It has been a long-standing issue but seems as though it is on its way to resolution: https://github.com/containers/podman-desktop/issues/1633.

I am waiting for a few months to make sure it is all sorted and will try again to see if it works then.

I'm not happy with Podman Desktop's Svelte GUI.

Antd or MUI (React) feel much more mature.

But they are working on it.

I don't know if that's really a core difference from podman. Assuming I track your meaning Podman has GUI management as well and it can be made to integrate with system and can produce Kubernetes manifests from the pods you define locally.

Optional extensions will follow their own lifecycle and update independently from Podman Desktop. As of this release you'll be able to see when there is an update available and install from within Podman Desktop #2655.

Podman Desktop 0.15 embeds Podman 4.5 in Windows and macOS installers #2115.

u/Chunkypewpewpew it's karpersky that has a false positive https://github.com/containers/podman-desktop/issues/700

Podman Desktop has a new release: you can check milestone v0.11.0 and Release Notes

> docker desktop is pretty dead now that it's got restrictive licensing etc...

It would probably be nice to hear more about why you think this is! I've certainly heard of some having to move away from Docker Desktop.

However, at the scale where you need a license (250 employees or 10 million $ in annual revenue) it's not quite as big of an issue, especially at their current pricing per seat: https://www.docker.com/pricing/

> stick to standard open source tools like Colima etc...

Sticking to open source is a great idea!

I think mentioning that Colima runs on macOS and Linux only at the moment is also a good idea: https://github.com/abiosoft/colima

A large market share of the Docker Desktop installs are Windows in particular (since it's "the one way" how most install Docker nowadays, as opposed to not really needing a GUI or the supporting tools on Linux).

In another comment I mentioned Podman Desktop as a mostly viable alternative: https://github.com/containers/podman-desktop

Then there's also Rancher Desktop as well: https://github.com/rancher-sandbox/rancher-desktop

Regardless, it's nice to see reputable orgs behind the open source projects as well, which gives a bit more credence to their chances of surviving for the years to come.
