Deploy Fly.io Proxy / deploy (push) Successful in 1m8s
## Summary - Introduce `tag:flyio-target` so services must explicitly opt in to be reachable by the fly.io proxy - Replace broad `tag:k8s` and `tag:homelab` grants with the new tag in the ACL rule and test - Add `tailscale.com/tags: "tag:k8s,tag:flyio-target"` annotation to docs, loki, and prometheus Ingresses - Switch Alloy push endpoints from `*.ops.eblu.me` (Caddy) to `*.tail8d86e.ts.net` (Tailscale Ingress) - Update docs: flyio-proxy, caddy, tailscale, forgejo (future public access + security checklist), expose-service-publicly ## Manual step (not in PR) Update the k8s operator OAuth client in the Tailscale admin console to include `tag:flyio-target` in its scope. Without this, the operator cannot assign the new tag to Ingress proxy nodes. ## Deployment order 1. **Pulumi ACLs** — `mise run tailnet-preview && mise run tailnet-up` 2. **OAuth client** — Manual update in Tailscale admin console 3. **K8s Ingresses** — `argocd app sync apps && argocd app sync docs loki prometheus` 4. **Fly.io proxy** — `mise run fly-deploy` 5. **Verify** — `mise run services-check`, check Grafana dashboards ## Test plan - [ ] `mise run tailnet-preview` shows clean diff - [ ] `argocd app diff docs`, `argocd app diff loki`, `argocd app diff prometheus` show only annotation additions - [ ] After deploy: Grafana dashboards show continued log/metric flow - [ ] `curl -sf https://docs.eblu.me` returns 200 - [ ] `mise run services-check` passes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/126

# Caddy
|
|
|
|
Reverse proxy for `*.ops.eblu.me` services with automatic TLS via ACME DNS-01.
|
|
|
|
## Quick Reference
|
|
|
|
| Property | Value |
|
|
|----------|-------|
|
|
| **Domain** | `*.ops.eblu.me` |
|
|
| **HTTPS Port** | 443 |
|
|
| **Config** | `ansible/roles/caddy/templates/Caddyfile.j2` |
|
|
| **Binary** | Custom build with Gandi DNS plugin |
|
|
|
|
## Why Caddy?
|
|
|
|
Caddy provides a single TLS termination point for all BlumeOps services:
|
|
|
|
- **Wildcard certificate** for `*.ops.eblu.me` via Let's Encrypt
|
|
- **DNS-01 challenge** using Gandi API (no port 80 needed)
|
|
- **Unified access** from k8s pods, containers, and tailnet clients
|
|
|
|
See [[routing]] for when to use `*.ops.eblu.me` vs `*.tail8d86e.ts.net`.

## Proxied Services
|
|
|
|
### Indri-Local Services
|
|
|
|
| Subdomain | Backend | Service |
|
|
|-----------|---------|---------|
|
|
| `forge.ops.eblu.me` | `localhost:3001` | [[forgejo]] |
|
|
| `registry.ops.eblu.me` | `localhost:5050` | [[zot]] |
|
|
| `jellyfin.ops.eblu.me` | `localhost:8096` | [[jellyfin]] |
|
|
|
|
### Kubernetes Services
|
|
|
|
K8s services are proxied via their Tailscale Ingress endpoints:
|
|
|
|
| Subdomain | Backend | Service |
|
|
|-----------|---------|---------|
|
|
| `grafana.ops.eblu.me` | `grafana.tail8d86e.ts.net` | [[grafana]] |
|
|
| `argocd.ops.eblu.me` | `argocd.tail8d86e.ts.net` | [[argocd]] |
|
|
| `docs.ops.eblu.me` | `docs.tail8d86e.ts.net` | [[docs]] (now publicly available at `docs.eblu.me` via [[flyio-proxy]]) |
|
|
| `feed.ops.eblu.me` | `feed.tail8d86e.ts.net` | [[miniflux]] |
|
|
| ... | ... | (see defaults/main.yml for full list) |
|
|
|
|
### TCP Services (Layer 4)
|
|
|
|
| Port | Backend | Service |
|
|
|------|---------|---------|
|
|
| 2222 | `localhost:2200` | Forgejo SSH |
|
|
| 5432 | `pg.tail8d86e.ts.net:5432` | [[postgresql]] |
|
|
|
|
## Configuration
|
|
|
|
Caddy is managed via the `caddy` Ansible role:
|
|
|
|
```bash
|
|
# Deploy caddy changes
|
|
mise run provision-indri -- --tags caddy
|
|
```
|
|
|
|
**Key files:**
|
|
- `ansible/roles/caddy/defaults/main.yml` - Service definitions
|
|
- `ansible/roles/caddy/templates/Caddyfile.j2` - Caddy config template
|
|
|
|
## Secrets
|
|
|
|
| Secret | Source | Description |
|
|
|--------|--------|-------------|
|
|
| `GANDI_BEARER_TOKEN` | 1Password | API token for DNS-01 challenges |
|
|
|
|
The token is written to `~/.config/caddy/gandi-token` (chmod 0600) and sourced by the Caddy wrapper script.
|
|
|
|
## Security Considerations
|
|
|
|
Caddy has no authentication layer — it is a plain reverse proxy. Access control relies entirely on Tailscale ACLs restricting which devices can reach indri on port 443. Currently `tag:homelab` and `autogroup:admin` can reach Caddy. The [[flyio-proxy]] no longer routes through Caddy — it pushes logs and metrics directly to [[loki]] and [[prometheus]] via their Tailscale Ingress endpoints.
|
|
|
|
## Custom Build
|
|
|
|
Caddy is built from source with the Gandi DNS plugin:
|
|
|
|
```bash
|
|
# Build location
|
|
~/code/3rd/caddy/bin/caddy
|
|
```
|
|
|
|
The build includes the `github.com/caddy-dns/gandi` plugin for ACME DNS-01 challenges.
