Erich Blume b197bd5f58 Adopt Dagger CI for docs build (Phase 2) (#157)
## Summary

Migrates the docs build pipeline to Dagger (Phase 2 of the Dagger CI adoption plan).

- **Backfill `date-modified` frontmatter** on all 80 docs — Dagger's `--src=.` excludes `.git`, so Quartz can't use git history for page dates. Frontmatter dates work with or without git.
- **New `docs-check-frontmatter` mise task + pre-commit hook** — validates all docs have `title`, `tags`, and `date-modified`
- **New Dagger functions** — `build_changelog` (towncrier in Python container) and `build_docs` (chains changelog → Quartz build in Node container, returns tarball)
- **Simplified CI workflow** — the ~44-line inline Quartz build (clone, npm ci, build, tar, cleanup) is replaced by `dagger call build-docs`. Changelog step remains local on the runner since towncrier needs to modify the host working tree for the git commit.

### Design decisions

- **Towncrier runs twice in CI**: once inside Dagger (for the docs tarball) and once on the runner (for the git commit). This is intentional — Dagger's directory export is additive and can't delete the consumed changelog fragments from the host.
- **Artifact hosting stays on Forgejo Releases** (not migrated to Forgejo Packages as the plan doc originally suggested). That migration can happen independently.
- **`date-modified` frontmatter** preserved even though `build_changelog` installs git — the git there is only for towncrier's `git add` call, not for history. The local iteration story (`dagger call build-docs --src=. --version=dev` with uncommitted changes) depends on frontmatter dates.

### Local iteration

```bash
dagger call build-docs --src=. --version=dev export --path=./docs-dev.tar.gz
tar tf docs-dev.tar.gz | head -20
```

## Deployment and Testing

- [x] `dagger call build-docs --src=. --version=dev` produces valid 1.1MB tarball (149 HTML pages)
- [x] Pre-commit hooks pass (including new `docs-check-frontmatter`)
- [ ] Full `workflow_dispatch` run after merge

# Forgejo
Git forge and CI/CD platform. **Primary source of truth for blumeops** (mirrored to GitHub).
## Quick Reference
| Property | Value |
|----------|-------|
| **URL** | https://forge.ops.eblu.me |
| **SSH** | `ssh://forgejo@forge.ops.eblu.me:2222` |
| **Local Ports** | 3001 (HTTP), 2200 (SSH) |
| **Config** | `ansible/roles/forgejo/templates/app.ini.j2` |
## Repositories
| Repo | Description |
|------|-------------|
| `eblume/blumeops` | Infrastructure as code (primary) |
| `eblume/alloy` | Grafana Alloy fork (CGO build) |
| `eblume/tesla_auth` | Tesla OAuth helper |
| Helm chart mirrors | cloudnative-pg-charts, grafana-helm-charts |
## CI/CD (Forgejo Actions)
**Runner:** Kubernetes pod with Docker-in-Docker sidecar
- Namespace: `forgejo-runner`
- Labels: `k8s`
- ArgoCD app: `forgejo-runner`
**Workflows:** `.forgejo/workflows/`
- `build-container.yaml` - Container image builds on tag
- `build-blumeops.yaml` - Documentation builds and releases
## Secrets (Forgejo Config)
Server configuration secrets managed via 1Password → Ansible:
- `lfs-jwt-secret`, `internal-token`, `oauth2-jwt-secret` - Forgejo server tokens
- `runner_reg` - Runner registration token (also in k8s via [[external-secrets]])
## Forgejo Actions Secrets
Repository-level secrets for CI/CD workflows, synced from 1Password via Ansible.
| Secret | 1Password Field | Used By | Purpose |
|--------|-----------------|---------|---------|
| `ARGOCD_AUTH_TOKEN` | `argocd_token` | `build-blumeops.yaml` | Sync docs app after release |
These secrets are injected as `${{ secrets.SECRET_NAME }}` in workflow files.
**IaC:** The `forgejo_actions_secrets` Ansible role syncs these secrets from 1Password to Forgejo via the Forgejo API. Run with:
```bash
mise run provision-indri -- --tags forgejo_actions_secrets
```
### API Token Setup (Manual, One-Time)
The Ansible role authenticates to the Forgejo API using a Personal Access Token (PAT). This PAT must be created manually:
1. Go to https://forge.ops.eblu.me/user/settings/applications
2. Create a new token with `write:repository` scope
3. Store it in 1Password → "Forgejo Secrets" item → `api-token` field
This is a bootstrapping requirement - the PAT enables IaC for all other secrets.
## Future: Public Access
Forgejo can be exposed publicly at `forge.eblu.me` via [[flyio-proxy]]. Since Forgejo runs natively on [[indri]] (not in k8s), the pattern is:
1. Create a k8s ExternalName Service pointing to indri's Tailscale IP
2. Create a Tailscale Ingress with `tailscale.com/tags: "tag:k8s,tag:flyio-target"`
3. Add the nginx server block and DNS CNAME
Exposing a dynamic, authenticated service like Forgejo requires a full security review before going live:
- Disable open user registration (require invites or admin approval)
- Configure fail2ban on indri with a filter for Forgejo's log format
- Ensure Forgejo logs the forwarded client IP (`X-Real-IP`) rather than the proxy's Tailscale IP
- Audit repository visibility defaults and permissions
- Rehearse the break-glass shutoff (`mise run fly-shutoff`)
See [[expose-service-publicly]] for the full howto and dynamic service checklist.
