Site Administration → Actions → Runners → Create Runner Token
One token for the Kubernetes runner (put in cluster Secret gitea-runner/gitea-runner, key token)
One token per NixOS host (isaiah, jeremiah, zeke, linode) — store in agenix secrets
Kubernetes Secret: Replace manifests/gitea-runner/secrets.yaml with a proper ExternalSecret (bitwarden) or manually apply the token. The current file is a placeholder with REPLACE_ME_WITH_ACTUAL_TOKEN.
Wire agenix secrets into each NixOS host. The module is at modules/nixos/gitea-runner.nix. None of the host files (hosts/jeremiah/default.nix, etc.) existed in the repo, so host wiring was not automated. Add to each host:
# In your host's imports or configuration:imports=[../../modules/nixos/gitea-runner.nix];age.secrets.gitea-runner-token.file=../../secrets/gitea/<hostname>-runner.age;greg.gitea-runner={enable=true;tokenFile=config.age.secrets.gitea-runner-token.path;};
Add KLAATU_TOKEN secret to the repo (Settings → Secrets) so the workflow actions can create PRs. This should be a Gitea token for the klaatu user with write access to greg/nixos.
Review act_runner chart version — used 0.2.5 as a recent known version. Verify against https://dl.gitea.com/charts/ and update if needed.
image-pull-secrets — the gitea-runner namespace will need an image-pull-secrets Secret (dockerconfigjson) for the internal registry, similar to the one in gitlab-runner. Consider adding an ExternalSecret for that.

## Gitea Actions Runner Infrastructure
This PR sets up Gitea Actions CI infrastructure for the homelab, including a Kubernetes runner and NixOS shell runners.
---
### What's Included
#### Kubernetes Runner (`manifests/gitea-runner/`)
- `namespace.yaml` — `gitea-runner` namespace
- `chart.yaml` — FluxCD `HelmRepository` + `HelmRelease` for the `act_runner` Helm chart (from `https://dl.gitea.com/charts/`)
- Configured with all standard image labels (Ubuntu, Fedora, CentOS Stream, Nix, plus ci-images from `src.thehellings.com/greg/`)
- Uses `image-pull-secrets` (same pattern as gitlab-runner)
- RBAC enabled
- `kustomization.yaml` — standard kustomization wiring
- `secrets.yaml` — **placeholder Secret** (`gitea-runner` / key: `token`) — see FIXME below
#### NixOS Shell Runner (`modules/nixos/gitea-runner.nix`)
- Uses `services.gitea-actions-runner` (exec/shell mode, no Docker)
- Options: `enable`, `hostnameLabel`, `tokenFile`, `threads`
- Automatically adds `bare-metal` label for isaiah/jeremiah/zeke hosts
- Automatically adds `linode` label for the linode host
- Token wired via `tokenFile` option → point to agenix secret path
#### Gitea Actions Workflows (`.gitea/workflows/`)
- `update-flake-lock.yaml` — weekly (Sunday midnight UTC) `nix flake update` + auto-PR via Gitea API
- `update-manifests.yaml` — weekly (Monday midnight UTC) manifest version scan scaffold + auto-PR

### What Greg Still Needs To Do
1. **Generate runner tokens** in Gitea:
- Site Administration → Actions → Runners → Create Runner Token
- One token for the Kubernetes runner (put in cluster Secret `gitea-runner/gitea-runner`, key `token`)
- One token per NixOS host (isaiah, jeremiah, zeke, linode) — store in agenix secrets
2. **Kubernetes Secret**: Replace `manifests/gitea-runner/secrets.yaml` with a proper ExternalSecret (bitwarden) or manually apply the token. The current file is a placeholder with `REPLACE_ME_WITH_ACTUAL_TOKEN`.
3. **Wire agenix secrets into each NixOS host**. The module is at `modules/nixos/gitea-runner.nix`. None of the host files (`hosts/jeremiah/default.nix`, etc.) existed in the repo, so host wiring was **not** automated. Add to each host:
```nix
# In your host's imports or configuration:
imports = [ ../../modules/nixos/gitea-runner.nix ];
age.secrets.gitea-runner-token.file = ../../secrets/gitea/<hostname>-runner.age;
greg.gitea-runner = {
enable = true;
tokenFile = config.age.secrets.gitea-runner-token.path;
};
```
4. **Add `KLAATU_TOKEN` secret** to the repo (Settings → Secrets) so the workflow actions can create PRs. This should be a Gitea token for the `klaatu` user with write access to `greg/nixos`.
5. **Review `act_runner` chart version** — used `0.2.5` as a recent known version. Verify against https://dl.gitea.com/charts/ and update if needed.
6. **`image-pull-secrets`** — the gitea-runner namespace will need an `image-pull-secrets` Secret (dockerconfigjson) for the internal registry, similar to the one in `gitlab-runner`. Consider adding an ExternalSecret for that.

1 & 2. Chart name and version (manifests/gitea-runner/chart.yaml)
chart: act_runner → chart: actions

3. ExternalSecret (manifests/gitea-runner/secrets.yaml)
Replaced the placeholder Secret with an ExternalSecret using the same pattern as manifests/monitoring/restic-secret.yaml:
No more FIXME placeholder — the runner token will be automatically synced from Bitwarden.
Addressed all three review items:
**1 & 2. Chart name and version** (`manifests/gitea-runner/chart.yaml`)
- `chart: act_runner` → `chart: actions`
- `version: "0.2.5"` → `version: "0.0.4"`
**3. ExternalSecret** (`manifests/gitea-runner/secrets.yaml`)
Replaced the placeholder `Secret` with an `ExternalSecret` using the same pattern as `manifests/monitoring/restic-secret.yaml`:
- ClusterSecretStore: `bitwarden-login`
- Bitwarden key: `11419680-5338-4f19-bdd9-b422007046af`, property: `password`
- Target secret name: `gitea-runner`, key: `token`
No more FIXME placeholder — the runner token will be automatically synced from Bitwarden.
