# github-runner
ArgoCD-managed repo-scoped Linux GitHub Actions runners for FlowerCore.
`astoltz` is a GitHub user account, not an organization, so each repository
needs its own runner registration. The existing Common runner remains
`Deployment/github-runner`; Sprint 29 adds one single-replica Deployment for
each top Linux-cost repo:
- `FlowerCore.Puppet`
- `FlowerCore.Signage`
- `FlowerCore.DMS`
- `FlowerCore.Telephony`
- `FlowerCore.Print.Web`
- `FlowerCore.Chat`
- `FlowerCore.MySQL`
- `FlowerCore.Kiosk.Linux`
Each runner uses `myoung34/github-runner:latest`, `EPHEMERAL=true`, and labels
`self-hosted,linux,fc-build-linux`. The shared `github-runner-token` Secret is
synced from the existing 1Password item `GitHub PAT (Runner Registration)` and
is consumed as `ACCESS_TOKEN`.
Do not `kubectl apply` this app over ArgoCD. Merge to `main`, let
`infra-github-runner` sync, then verify from `noc1`:
```bash
kubectl -n github-runner get deploy,pods,pvc
for repo in FlowerCore.Puppet FlowerCore.Signage FlowerCore.DMS FlowerCore.Telephony FlowerCore.Print.Web FlowerCore.Chat FlowerCore.MySQL FlowerCore.Kiosk.Linux; do
gh api "/repos/astoltz/$repo/actions/runners" \
--jq '.runners[] | select((.labels[].name == "fc-build-linux") and (.status == "online")) | {name,status,busy,labels:[.labels[].name]}'
done
```
`LinuxRunnerOffline` is declared in `apps/monitoring/noc-monitoring.yaml` and
fires when any Common or top-8 Linux runner deployment has no available replica
for 10 minutes.
