Podman Desktop VS gvisor

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.

Isn't gVisor kind of this as well?

"gVisor is an application kernel for containers. It limits the host kernel surface accessible to the application while still giving the application access to all the features it expects. Unlike most kernels, gVisor does not assume or require a fixed set of physical resources; instead, it leverages existing host kernel functionality and runs as a normal process. In other words, gVisor implements Linux by way of Linux."

This sort of feels like seeing someone riding a bike and saying: why don’t they just get a car? The simple fact is that containers and VMs are quite different. Whether something uses VMX and friends or not is also a red herring, as gVisor also “rolls it own VMM” [1].

There's two major production-ready Go-based operating system(-ish) projects:

- Google's gVisor[1] (a re-implementation of a significant subset of the Linux syscall ABI for isolation, also mentioned in the article)

- USBArmory's Tamago[2] (a single-threaded bare-metal Go runtime for SOCs)

Both of these are security-focused with a clear trade off: sacrifice some performance for memory safe and excellent readability (and auditability). I feel like that's the sweet spot for low-level Go - projects that need memory safety but would rather trade some performance for simplicity.

It uses gVisor to create a TCP/IP stack in userspace, and starts a wireguard interface on it, which the HTTP server from http.Serve listens on. The library will print a URL after startup, where you can access your server. You can create multiple listeners in one binary.

The playground compiles the program with GOOS=linux, GOARCH=amd64 and runs the program with gVisor. Detailed documentation is available at the gVisor site.

You could use a container sandbox like gVisor, light virtual machines as containers (Kata containers, firecracker + containerd) or full virtual machines (virtlet as a CRI).
