Docker Desktop isn’t really about the GUI so much as the management of, and host integration with, a Linux VM for running on non-Linux OSes. Notably, there’s no Docker Desktop for Linux, only macOS and Windows.

Yep. Podman takes cares of those things using the `podman machine` sub-command. From what I understand, currently only macOS might be working, but Windows support will be coming if it's not already there.

the only issue really left is that volume mounts don't work with podman machine as of yet. The issue has been live on github for awhile, but its finally getting traction. Likely because of the recent Docker for Desktop changes.

EDIT: github link: https://github.com/containers/podman/issues/8016

AFAICT podman machine relies on VirtualBox. This would be an enormous performance and resource regression on MacOS — Docker Desktop uses the much more performant and resource-conscious native hypervisor frameworks instead.

This doesn't seem accurate.

According to a post on the podman website: "Current implementation relies on qemu which currently has some platform dependencies." [1]

I also just checked on my machine and it is indeed running on Qemu.

IIRC Qemu also has support for Apple's Hypervisor.framework.

You are correct - thanks!

If true, also untenable since last I checked VBox doesn't plan to support ARM hosts (including the new Mac chipset)

Looks like they are adding it https://twitter.com/glours/status/1438526841577357315

I quote: "A dream coming true for a lot of #linux users, @dieuthicao announced that we’ll start working on a #Linux version of @docker Desktop"

What does Docker Desktop even really offer on Linux? k8s, I guess? There are other open-source (Docker Desktop is proprietary ofc) ways to do that.

As a Linux user, far from a dream at all, really.
