DNS hosting provider for the `eblu.me` domain, managed via Pulumi IaC.
## Quick Reference
| Property | Value |
|----------|-------|
| **Domain** | `eblu.me` |
| **Provider** | Gandi LiveDNS |
| **IaC** | `pulumi/gandi/` |
| **Stack** | `eblu-me` |
## What It Does
Gandi hosts the DNS records that make `*.ops.eblu.me` resolve to [[indri]]'s Tailscale IP (100.98.163.89). Since Tailscale IPs are not publicly routable, this gives services real DNS names while keeping them private to the tailnet.
The target IP is resolved dynamically from `indri.tail8d86e.ts.net` at deploy time, so if indri's Tailscale IP changes, re-running the deployment is sufficient.
## DNS Records
| Record | Type | Value | TTL |
|--------|------|-------|-----|
| `*.ops.eblu.me` | A | indri's Tailscale IP | 300s |
| `ops.eblu.me` | A | indri's Tailscale IP | 300s |
Both records point to [[indri]], which runs [[caddy]] as the reverse proxy for all services. See [[routing]] for the full service URL map.
## Pulumi Configuration
The Pulumi program lives in `pulumi/gandi/`:
-`__main__.py` - Creates the two A records via `pulumiverse_gandi`
A break-glass override is available via the `BLUMEOPS_REVERSE_PROXY_IP` environment variable, which bypasses dynamic IP resolution.
## TLS Integration
[[caddy]] uses Gandi's API separately (via `GANDI_BEARER_TOKEN`) for ACME DNS-01 challenges to obtain a wildcard Let's Encrypt certificate for `*.ops.eblu.me`. This is a different credential from the Pulumi PAT.
## Authentication
Gandi requires a Personal Access Token (PAT) for API access. PATs have a maximum lifetime of 90 days (currently set to 30). See [[gandi-operations]] for deployment and PAT cycling instructions.
