feat: tart macOS vm's as job container

[ChristopherHX]

adds the tart:// protocol to platform mapping

e.g. -P macos-14=tart://ghcr.io/cirruslabs/macos-sonoma-base:latest if you have a mac.

I have written the code in a payed dedicated host machine that is now deallocated, expenses satisfied by sponsoring of my other act based project while I don't see anything here, as I don't own a mac.

add-path is probably broken, but I ignore the fact as of now.

Just starting to test this out and it looks good on first pass. testing on a mac m1 mbp

if the gh action step fails, the container is left in a running state.

if the container fails to start (say 2 vm limit is reached), the container is left in a stopped state.

I've been using ssh, with tart / parallels / qemu to run jobs with -P ${PLATFORM}=-self-hosted on windows/macos/linux vms for the last year (https://gist.github.com/YOU54F/3ac099e54e48a31a69ac2d671aa878f6 / https://gist.github.com/YOU54F/789c53ae8380a1f90325952615635f8a )

I had a play with your runner.server & github-act-runner to build gh actions in my homelab with a set of vm's on a few diff machines. Cheers for your work

Does --rm change anything here? Act has a feature for docker containers to keep them running if a step fails so you can debug, but reusing the vm has not been working in my testing..

Yeah I have written and use my runner.server prog exactly for such a use case, but mostly with actions/runner as the actual runner.

I'm seeing not test coverage

This requires a self-hosted runner, macos-14 github runner cannot be used due to running already in a Virtual Machine.

Or stubbing tart, but then do we really know if tart works? I wanted in the past to have a tart emulator that fakes creating VM, but didn't find anything,

This is not like intel macOS with nested virtualization... :(.

Added a test for the error caused by using the tart mapping in linux where it is not supported, now coverage is green.

We have a coverage collection problem for platforms outside of linux anyway.

Merge impossible, due to lack of interest.
