Running Windows and Linux Containers at the same time on a single machine

A pretty niche requirement I had when working with a particular workload, but while researching it I seen the question pop up a couple of times on this sub so I thought I'd post it here for ref - hope it's on topic enough for the mods as I'm not sure where else it could fit :)

The problem:
Essentially we have a stack transitioning to Linux but parts of it remian on windows and it's tricky to get it all running locally, edit to add: the real constraints being having the workloads communicate with eachother across the same network, in a reproducible way. Virtualized infrastructure (sql, storage, servicebus) in Linux accessible from Windows, windows backend containers accessible from linux frontend containers, etc

I wanted to see how realistic it would be to automate this process including all the necessary configuration, from zero to running

The solution:
In the end the most 'reliable' solution was running Windows host with Docker Desktop in Windows Containers mode, and installing PodMan inside a WSL2 instance, after some firewall/nat trickery I got the services talking to eachother.

The automation:
I didn't think there was much value in simply demoing this without it being reproducible and documented, so I (with the aid of Claude) built a dotnet10 WPF app toolkit that can configure a machine in this way, as well as convert mixed-OS helm charts into docker/podman compose files that can be consumed by the underlying engines

The result:

A very particular set of tools I hope no one else is unlucky enough to need, but it's all up on github:
