qubes-mirage-firewall VS podman

2) https://github.com/mirage/qubes-mirage-firewall is by far a better firewall for Qubes than OpenBSD ever will be - unikernels are far more secure than a traditional operating system is and you can read all about it on https://mirageos.org/

That's correct. It does mean that the closest to a self-contained program you can run is a unikernel like the mirage-firewall, unfortunately. On the upside, those remain easily portable to essentially anything that can run VMs so long as you adjust the image format.

That sounds similar to a unikernel. There are actual uses for those in seL4 and Qubes OS such as a firewall-qube (in theory unikernel qubes should be able to take far less system resources to run than full Linux+distro qubes).

Here's one that is "production" ready: the Mirage-Firewall microkernel running on Qubes OS.[0]

sys-net, sys-firewall and other administrative vms should slowly migrate to unikernels instead of running linux, which should help with ram usage. The mirage.io project seems to build a couple qubes vms, for example https://github.com/mirage/qubes-mirage-firewall is a firewall which they indicate to give 64Mb of ram.

A lot of well-known Docker alternatives emerged at this point, the most commonly recommended of which must be Podman (along with Podman Desktop). This is what I use on my Windows machines, and this was the first solution that I tried on the Macbook as well.

Podman

Even though we will focus on Docker for this article, I wanted to mention that there are more container creation and management tools such as Podman, Rkt, and so on.

By using containerization, the application will always have the same configuration that is used in the development environment and production environment. There is no more "It works on my machine". Some examples of containerization technologies are Docker and Podman.

Podman Documentation. Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System.

AFAIK podman either already supports pods in quadlet container files, or will in the near future. https://github.com/containers/podman/pull/20762

Podman as a devcontainers engine doesn't currently work if you use devcontainer features [1] or (and this sounds like you're issue) if you use WSL2.

I haven't submitted the WSL2 issue to the Podman team yet. If you get to it before I do, can you like it here?

You can also use their Oracle Linux Docker images with the database preinstalled using either Podman or Docker. Just make absolutely sure you are downloading something you are licensed to use, because it seems really easy to accidentally infringe copyright via this method.
