Deploy Fly.io Proxy / deploy (push) Successful in 1m28s
## Summary Expose Forgejo publicly at `forge.eblu.me` via the Fly.io reverse proxy — the first dynamic, authenticated public-facing service. - **Forgejo hardening:** Domain changed to forge.eblu.me, SSH stays on forge.ops.eblu.me, reverse proxy trust headers configured, local registration locked to external-only (Authentik SSO) - **Tailscale Ingress:** ExternalName Service + Ingress in tailscale-operator creates forge.tail8d86e.ts.net endpoint - **Fly.io proxy:** nginx server block with rate-limited auth endpoints (3r/s), fail2ban with custom nginx-deny action, security headers, /swagger blocked, WebSocket support, 512m body limit - **Authentik:** OAuth callback updated to forge.eblu.me - **DNS/TLS:** CNAME record in Pulumi, cert in fly-setup - **Rename:** ~29 files updated from forge.ops.eblu.me to forge.eblu.me (HTTPS refs only; SSH, container builds, and Caddy table kept as-is) ## Deployment Order 1. `mise run provision-indri -- --tags forgejo` (config changes) 2. Verify forge.ops.eblu.me still works 3. `argocd app set tailscale-operator --revision feature/forge-public && argocd app sync tailscale-operator` 4. Verify `curl https://forge.tail8d86e.ts.net` 5. `cd fly && fly deploy` 6. Verify pre-DNS: `curl -H "Host: forge.eblu.me" https://blumeops-proxy.fly.dev/` 7. `fly certs add forge.eblu.me -a blumeops-proxy` 8. `argocd app set authentik --revision feature/forge-public && argocd app sync authentik` 9. `mise run dns-preview && mise run dns-up` 10. Full verification (see below) 11. Rehearse `mise run fly-shutoff` 12. After merge: reset ArgoCD revisions to main, re-sync ## Verification Checklist - [ ] forge.eblu.me loads, shows public repos - [ ] forge.ops.eblu.me still works from tailnet - [ ] SSH clone via forge.ops.eblu.me:2222 works - [ ] HTTPS clone via forge.eblu.me works - [ ] UI shows forge.eblu.me for HTTPS clone, forge.ops.eblu.me for SSH - [ ] /swagger returns 403 - [ ] Rapid login attempts trigger 429 rate limit - [ ] fail2ban bans after 5 failed logins in 10 minutes - [ ] ArgoCD can still sync (SSH unaffected) - [ ] `mise run fly-shutoff` stops all public traffic - [ ] `mise run services-check` passes Reviewed-on: #278

# Service Routing
|
|
|
|
Services are accessible via three DNS domains with different reachability.
|
|
|
|
## DNS Domains
|
|
|
|
| Domain | Proxy | Reachable From |
|
|
|--------|-------|----------------|
|
|
| `*.eblu.me` | [[flyio-proxy]] (Fly.io → Tailscale tunnel) | Public internet |
|
|
| `*.ops.eblu.me` | Caddy on indri | k8s pods, docker containers, tailnet clients |
|
|
| `*.tail8d86e.ts.net` | Tailscale MagicDNS | Tailnet clients only |
|
|
|
|
**Use `*.ops.eblu.me`** for services that need pod-to-service communication. Use `*.eblu.me` for services exposed publicly via Fly.io.
|
|
|
|
## Caddy Services (`*.ops.eblu.me`)
|
|
|
|
DNS points to [[indri]]'s Tailscale IP. TLS via Let's Encrypt (ACME DNS-01 with Gandi).

## Public Services (`*.eblu.me`)
|
|
|
|
DNS CNAMEs point to `blumeops-proxy.fly.dev`. TLS via Fly.io-managed Let's Encrypt. Traffic tunnels back to the homelab over Tailscale. Only services tagged `tag:flyio-target` are reachable by the proxy — see [[flyio-proxy]] for details.
