You can interact directly with your builds by connecting to the runner over SSH. This is helpful for troubleshooting your manifests, or just getting a quick temporary environment to test something in.
When a build fails, the VM stays alive for an extra ten minutes, and you'll be presented with instructions on how to connect to the runner via SSH, e.g.:
$ ssh -t email@example.com connect 81809 Connected to build job #81809 (failed): https://builds.sr.ht/jobs/~sircmpwn/81809 Your VM will be terminated 4 hours from now, or when you log out. bash-5.0 $
In addition to connecting to failed builds over SSH, you can add
to your manifest to always enable SSH access. Then,
you'll be able to interact with your build as it runs.
