Using a labelled self-hosted runner from act

[m-mcgowan]

I have a job that runs on a self-hosted runner which I've registered in Github. Is it possible for act to direct the job execution to that runner so I can test the job locally?

Some more details. I've installed the github self-hosted runner service to a RasPi, which has some specific hardware attached that is used during CI testing. On my development machine, I'd like to be able to have the job run on that self-hosted runner in the same way Github does.

The workflow file contains:

jobs:
   myjob:
          runs-on: [self-hosted, linux, custom_tag]

I've seen the -P option that can be used to map these tags to docker images, but I'm not sure how that can help me run the job in a specific runner.

I'm probably misunderstanding something, so thanks for any help!
