## Summary
Extends ringtail from a desktop/gaming NixOS box into an infrastructure node with a k3s cluster, secrets management, and a Forgejo Actions
runner for building containers with Nix.
### K3s cluster
- Single-node k3s with Traefik/ServiceLB/metrics-server disabled (minimal footprint)
- TLS SAN set to `ringtail.tail8d86e.ts.net` so ArgoCD on indri can manage it via Tailscale
- Containerd registry mirrors pull through Zot on indri (`k3s-registries.yaml`)
- Tailscale interface added to `trustedInterfaces` for cross-node ArgoCD access
- `kubectl` added to system packages
### 1Password Connect + External Secrets Operator
- Four new ArgoCD apps targeting `k3s-ringtail`: `1password-connect-ringtail`, `external-secrets-crds-ringtail`, `external-secrets-ringtail`,
`external-secrets-config-ringtail`
- Reuses the same Helm charts/values as indri, just pointed at ringtail's k3s API server
- Bootstrap secrets (`op-credentials`, `onepassword-token`) provisioned by Ansible pre_tasks via `op read`, then applied to the `1password`
namespace in post_tasks
### Systemd Forgejo Actions runner
- Native `services.gitea-actions-runner` with `forgejo-runner` package — no DinD, no k8s pod, runs directly on the NixOS host
- Label `nix-container-builder:host` — jobs execute on the host with `nix`, `skopeo`, `nodejs`, etc. in PATH
- Registration token fetched from 1Password (`Forgejo Secrets/runner_reg`) by Ansible and written to `/etc/forgejo-runner/token.env`
- Runner's dynamic user (`gitea-runner`) added to `nix.settings.trusted-users` for nix daemon access
### Nix container build workflow
- New `.forgejo/workflows/build-container-nix.yaml` triggers on `*-nix-v[0-9]*` tags (e.g. `nettest-nix-v1.0.0`)
- Builds with `nix build -f containers/<name>/default.nix`, pushes to Zot via `skopeo copy`
- Existing Dockerfile workflow guarded with `if: !contains(github.ref_name, '-nix-v')` to avoid double-triggering
### Mise task updates
- `container-tag-and-release` auto-detects `default.nix` vs `Dockerfile` and uses the appropriate tag format (`-nix-v` vs `-v`)
- `container-list` shows build type indicator (`[nix]` / `[dockerfile]`)
## Post-merge
1. `mise run provision-ringtail` — deploys k3s token, runner token, NixOS rebuild
2. Register k3s cluster in ArgoCD (first time only):
```fish
ssh ringtail 'sudo cat /etc/rancher/k3s/k3s.yaml' | \
sed 's|127.0.0.1|ringtail.tail8d86e.ts.net|' > /tmp/k3s-ringtail.yaml
set -x KUBECONFIG /tmp/k3s-ringtail.yaml
argocd cluster add default --name k3s-ringtail
3. Sync ArgoCD apps in order: 1password-connect-ringtail -> external-secrets-crds-ringtail -> external-secrets-ringtail ->
external-secrets-config-ringtail
4. Verify runner: ssh ringtail 'systemctl status gitea-runner-nix-container-builder'
5. Check Forgejo admin panel for ringtail-nix-builder runner online
6. Test: create containers/<name>/default.nix, tag with <name>-nix-v0.1.0

## Summary
- Added a new `build_quartz` Dagger function that builds the Quartz site from a pre-processed source tree (no towncrier)
- Reordered the release workflow so towncrier runs **once** on the runner, then passes the updated working tree to `build-quartz`
- `build_docs` and `build_changelog` are preserved for standalone use — `build_docs` now delegates to `build_quartz` internally
## Motivation
Previously towncrier ran twice per release: once inside a Dagger container (via `build_docs` → `build_changelog`) and once on the runner to capture CHANGELOG.md changes for the git commit. This was wasteful and fragile — if towncrier behavior changed, the two runs could produce different results.
## Test plan
- [ ] Review diff to confirm workflow step ordering is correct
- [ ] Trigger a release and confirm towncrier runs only once
- [ ] Verify the docs tarball contains the updated CHANGELOG.md
- [ ] `dagger call build-quartz --src=. --version=vX.Y.Z` should work standalone

## Summary
With Phases 1 and 2 complete, the runner image no longer needs most of its bundled tools. This PR strips it down and adds what was missing.
**Removed** (now inside Dagger containers):
- Node.js 24.x
- Docker CLI + buildx plugin
- skopeo
- gnupg, lsb-release, xz-utils
**Added:**
- `tzdata` — fixes the TZ env var (#159, #160, #161) so `TZ=America/Los_Angeles` actually works
- `flyctl` — was being installed from scratch every release
**Workflow changes:**
- Remove "Ensure Dagger CLI" bootstrap steps from both workflows (Dagger is in the image)
- Remove "Install flyctl" step from build-blumeops (flyctl is in the image)
- Remove job-level `TZ` from build-blumeops (moved to runner configmap `runner.envs`)
- Set `TZ: America/Los_Angeles` in runner configmap so all job containers inherit it
## Deployment
After merge:
1. Build and release the new runner image: `mise run container-release forgejo-runner v2.0.0`
2. Sync the runner: `argocd app sync forgejo-runner`
3. Verify: `kubectl -n forgejo-runner exec deploy/forgejo-runner -c runner -- date` (but the real test is running a docs release and checking the changelog date)
Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/162
## Summary
The runner pod's `TZ` env var (#159, #160) doesn't propagate to workflow job containers — jobs run inside Docker containers spawned by the DinD sidecar, not in the runner process itself. Set `TZ: America/Los_Angeles` at the job level so `uvx towncrier build` uses the correct timezone.
This is the actual fix for the Feb 12 changelog dates. The runner pod TZ is still useful for runner daemon logs but doesn't affect job execution.

## 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

## Summary
- The Fly.io nginx proxy caches docs responses for 24h (`proxy_cache_valid 200 1d`)
- After a release, docs.eblu.me kept serving stale content until the cache expired
- This caused v1.5.4 to show v1.5.3 on the CHANGELOG page
- Adds `flyctl` install and `fly ssh console` cache purge steps to the build workflow, running after the ArgoCD deploy completes
## Test plan
- [ ] Next release should show the correct version on docs.eblu.me/CHANGELOG immediately
- [ ] Verify the `fly ssh console` command succeeds in the workflow logs

## Summary
- Adds a Fly.io reverse proxy (`blumeops-proxy`) that tunnels public traffic to homelab services over Tailscale
- First service exposed: `docs.eblu.me` — the Quartz static docs site
- Includes Pulumi IaC for Tailscale auth key/ACLs and Gandi DNS CNAME
- Adds mise tasks (`fly-deploy`, `fly-setup`, `fly-shutoff`) and Forgejo CI workflow
## Key details
- Fly.io Firecracker VMs support TUN devices natively — no userspace networking needed
- Tailscale auth key is `preauthorized=True` to avoid device approval hangs on container restarts
- nginx caches aggressively for the static site; health check is on the default_server block
- ACLs restrict `tag:flyio-proxy` to `tag:k8s` on port 443 only
- DNS CNAME deployed and verified: `docs.eblu.me` → `blumeops-proxy.fly.dev`
## Test plan
- [x] `curl -sf https://blumeops-proxy.fly.dev/healthz` returns `ok`
- [x] `curl -I -H "Host: docs.eblu.me" https://blumeops-proxy.fly.dev/` returns 200 with `X-Cache-Status`
- [x] `curl -I https://docs.eblu.me/` returns 200 with valid Let's Encrypt cert
- [x] `dig forge.ops.eblu.me` still resolves to 100.98.163.89 (private services unaffected)
- [x] Set `FLY_DEPLOY_TOKEN` Forgejo Actions secret for CI auto-deploy

## Summary
Fixes the "isn't yet tracked by git, dates will be inaccurate" warnings by using Quartz's `-d docs` flag instead of symlinking.
## Problem
The previous approach symlinked `content -> docs`, but git doesn't follow symlinks. When Quartz asked git about `content/index.md`, git had no history for that path.
## Solution
Use `npx quartz build -d docs` to tell Quartz to read from `docs/` directly. Now when Quartz asks git about `docs/index.md`, git finds the actual file history.
- CHANGELOG.md is copied (not symlinked) into `docs/` for the build, then removed
- All other files have accurate git-based dates
## Testing
Tested locally - build produces no warnings.

## Summary
Fixes the "isn't yet tracked by git, dates will be inaccurate" warnings in the Build docs step by restructuring how Quartz builds the documentation.
## Problem
Previously, we copied docs into Quartz's content folder. Since this was inside a fresh Quartz clone with no history of our files, the `CreatedModifiedDate` plugin couldn't determine accurate dates.
## Solution
Build Quartz from within the blumeops repo instead:
1. Copy Quartz's build system (quartz/, package.json, etc.) into the workspace
2. Symlink `content` -> `docs` (preserves git history)
3. Symlink `docs/CHANGELOG.md` -> `../CHANGELOG.md`
4. Build from workspace root where git can trace file history
5. Clean up artifacts after creating tarball
## Deployment and Testing
- [ ] Run build workflow and verify no "not tracked by git" warnings
- [ ] Verify file dates appear correctly on built docs site

- Move CHANGELOG.md to repository root (still copied into docs during Quartz build)
- Add CHANGELOG link to docs index page
- Update doc-links script to recognize build-time docs from repo root
## Changes

## Summary
- Move all existing zettelkasten cards from `docs/` to `docs/zk/` as a temporary holding area
- Update `zk-docs` mise task to look in the new location
- Add `docs/README.md` explaining the Diataxis-based restructuring plan and target audiences
## Context
This is phase 1 of a multi-phase documentation restructuring effort. The goal is to reorganize docs to follow the Diataxis framework while serving multiple audiences:
1. Erich (owner) - knowledge graph/zk
2. Claude/AI agents - memory and context enrichment
3. New external readers - high-level overview
4. Potential operators/contributors - onboarding
5. Replicators - people wanting to duplicate the approach
## Testing
- [x] Verified `mise run zk-docs` still works with the new path
- [x] Updated obsidian.nvim config (in ~/.config/nvim) to point to new path
## Note
The obsidian.nvim config change is outside this repo but was made as part of this work.
