@zackgalbreath I moved the close stuff to spackbot since I am also deleting the mirror there spack/spackbot#68

Could you review those changes to make sure I didn't break something else as well.

You will also need to bump the version number for gh-gl-sync in .github/workflows/custom_docker_builds.yml and k8s/custom/gh-gl-sync/cron-jobs.yaml

This is looking pretty good @kwryankrattiger thanks! Couple requests:

I feel like this is not rebased on the latest main, to make it easier for me to make another review pass, can you rebase it?

Somehow the nested contents of the volumes and volumeMounts sections in the deployments are indented differently between spackbot-spack-io and spackbotdev-spack-io. Can you make them match?

Thanks!
