Recurring maintenance batch (2026-05-27) (#360) Bundle of recurring overdue tasks: - Ringtail flake update - Security & compliance report review - Tooling deps bump (prek, fly, mise, forgejo workflows) - Top stale doc review - Top stale service review (if trivial) Larger items (service version bumps requiring upgrades, non-local container migration) split out as separate PRs.

Add Fly.io public reverse proxy for docs.eblu.me (#120) ## 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/120

C1: SHA-pin tooling dependencies (2026-04 cycle) (#344) ## Summary Monthly tooling dependency refresh, with a one-time conversion from version-tag pins (`rev = "vX.Y.Z"`, `image:tag`, `>=`) to SHA / digest pins everywhere. ## Changes - **prek hooks**: all `rev = "vX.Y.Z"` → commit SHA + `# vX.Y.Z` comment. Bumped trufflehog (3.94.0→3.95.2), kingfisher (1.91.0→1.97.0), ruff (0.15.7→0.15.12), shfmt (3.13.0→3.13.1), prettier (3.8.1→3.8.3), actionlint (1.7.11→1.7.12). - **fly/Dockerfile**: tag pins → `image@sha256:...` digest pins. Bumped nginx (1.29.6→1.30.0-alpine), tailscale (v1.94.1→v1.94.2 — still inside the safe pre-1.96.5 range), alloy (v1.14.1→v1.16.0). - **mise-tasks**: PEP 723 inline deps converted from `>=` to `==` (PEP 508 doesn't support hashes inline). All scripts pinned to current latest: rich 15.0.0, typer 0.25.0, pyyaml 6.0.3, httpx 0.28.1. - **prek `additional_dependencies`**: ansible-lint==26.4.0, ansible-core==2.20.5. - **taplo-lint**: pass `--no-schema`. Upstream's `--default-schema-catalogs` returns a format taplo v0.9.3 can't parse — we don't validate against TOML schemas anyway, so this turns off the broken catalog fetch. - **docs/update-tooling-dependencies**: documents the SHA-pin convention, `docker buildx imagetools inspect` for digest lookup, and `prek clean` before re-verifying (cache grows to several GiB). Forgejo workflow `actions/checkout@v6.0.2` was already at the latest SHA — no change. ## Test plan - [x] `prek run --all-files` passes after `prek clean` - [x] `deploy-fly` workflow builds and deploys the new fly image on merge - [x] `fly status -a blumeops-proxy` healthy after deploy - [x] Spot-check a few mise tasks (`mise run blumeops-tasks`, `mise run docs-check-links`) to confirm pinned deps resolve cleanly Reviewed-on: https://forge.eblu.me/eblume/blumeops/pulls/344

C0: black-hole /mirrors/* at Fly edge + name-and-shame scrapers A $29.60 Fly bill traced to ~1.25 TB/30d egress on forge.eblu.me (99.95% of all proxy egress), ~71% of it AI scrapers (Meta meta-externalagent, OpenAI GPTBot, Amazonbot, Bytespider) crawling the public mirror repos' infinite git-history URL space and timing out Forgejo. robots.txt already disallowed /mirrors/ but those agents ignore it, so enforce at the edge: return 403 (^~ to beat the regex asset locations), served as a roll-of-dishonour page with an X-Naughty-Scrapers header. Mirrors stay reachable on the tailnet via forge.ops.eblu.me. Tier 2 (UA denylist + Anubis) and the Cloudflare rejection are documented in docs/explanation/ai-scraper-mitigation.md.

Add Fly.io proxy observability via embedded Alloy (#123) ## Summary - Embed Grafana Alloy in the Fly.io proxy container to collect nginx JSON access logs (→ Loki) and derive request rate, latency histogram, cache status, and bandwidth metrics (→ Prometheus) - Add nginx `stub_status` endpoint for connection-level metrics (active/reading/writing/waiting) - Create two Grafana dashboards: **Docs APM** (per-service view filtered by `host="docs.eblu.me"`) and **Fly.io Proxy Health** (aggregate proxy health across all upstream services) ## Changed Files | File | Change | |------|--------| | `fly/nginx.conf` | Add JSON `log_format` + `access_log`, add `stub_status` endpoint | | `fly/Dockerfile` | COPY Alloy binary from `grafana/alloy:v1.5.1`, COPY `alloy.river` config | | `fly/alloy.river` | **New** — Alloy config: log tailing, metric extraction, remote_write | | `fly/start.sh` | Start Alloy after Tailscale, before nginx | | `argocd/manifests/grafana-config/dashboards/configmap-docs-apm.yaml` | **New** — Docs APM dashboard | | `argocd/manifests/grafana-config/dashboards/configmap-flyio.yaml` | **New** — Fly.io Proxy Health dashboard | | `argocd/manifests/grafana-config/kustomization.yaml` | Register new dashboard configmaps | | `docs/reference/services/flyio-proxy.md` | Document observability setup | ## Deployment and Testing - [ ] `mise run fly-deploy` — rebuild container with Alloy - [ ] `curl https://docs.eblu.me/` — generate traffic - [ ] `fly logs -a blumeops-proxy` — verify Alloy startup - [ ] Query Prometheus: `flyio_nginx_http_requests_total{instance="flyio-proxy"}` - [ ] Query Loki: `{instance="flyio-proxy", job="flyio-nginx"}` - [ ] `argocd app sync grafana-config` — deploy dashboards - [ ] Verify dashboards show data in Grafana - [ ] `mise run services-check` — no regressions Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/123

Add Fly.io public reverse proxy for docs.eblu.me (#120) ## 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/120
