## Summary - Updated frontmatter `title:` in all 63 doc cards from slug-case to human-readable (e.g. `borgmatic` → `Borgmatic`, `ai-assistance-guide` → `AI Assistance Guide`) - Titles now closely match file stems so `[[wiki-links]]` render naturally without alternate anchor text - Corrected titles that diverged from stems (e.g. `host-inventory` → `Hosts`, `grafana-alloy` → `Alloy`, `argocd-applications` → `Apps`) - Deleted `title-test-alpha.md` and `title-test-beta.md` test cards and removed their reference index entry ## Deployment and Testing - [x] `docs-check-links` passes — all wiki-links valid - [x] `docs-check-index` passes - [x] `docs-check-filenames` passes - [ ] Verify titles render correctly on docs site after deploy Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/117

# Gandi
|
|
|
|
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`
|
|
- `Pulumi.eblu-me.yaml` - Stack config (domain, subdomain)
|
|
|
|
Stack config values:
|
|
|
|
| Key | Value |
|
|
|-----|-------|
|
|
| `blumeops-dns:domain` | `eblu.me` |
|
|
| `blumeops-dns:subdomain` | `ops` |
|
|
|
|
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.
