Gandi DNS Management

This Pulumi project manages DNS records for eblu.me via Gandi LiveDNS.

What It Does

Creates DNS records that point *.ops.eblu.me to indri's Tailscale IP.

Why indri? indri hosts Caddy, the reverse proxy for all blumeops services. All *.ops.eblu.me requests route through Caddy, which proxies to the appropriate backend service (either on indri itself or in the k8s cluster).

Since Tailscale IPs (100.x.x.x) are not routable on the public internet, these DNS records effectively make services accessible only from within the tailnet, while still using real, resolvable DNS names.

The target IP is resolved dynamically from indri.tail8d86e.ts.net at deploy time, so if indri's Tailscale IP changes, just re-run the deployment.

Setup

cd pulumi/gandi
uv sync
pulumi stack select eblu-me  # or: pulumi stack init eblu-me

Authentication

This project requires a Gandi Personal Access Token (PAT) with LiveDNS permissions.

The PAT expires every 30 days and must be cycled manually.

Cycling the PAT

Go to Gandi PAT Management
Create a new PAT:
- Name: blumeops-pulumi (or similar)
- Expiration: 30 days (maximum is 90; shorter is fine if used rarely)
- Permissions required:
  - Manage domain name technical configurations (required for DNS records)
  - See and renew domain names
- Optional permissions (enabled but not strictly required):
  - See & download SSL certificates
  - Manage Cloud resources
  - See Cloud resources
  - View Organization
  - Deploy Web Hosting instances
  - Manage Web Hosting instances
  - See and renew Web Hosting instances

Update 1Password:

# Update the existing item with the new PAT value
op item edit mco6ka3dc3rmw7zkg2dhia5d2m pat="<NEW_PAT_VALUE>" --vault vg6xf6vvfmoh5hqjjhlhbeoaie

Delete the old PAT from Gandi admin console

Running with Authentication

The mise task handles fetching the PAT from 1Password:

mise run dns-up        # Preview and apply changes
mise run dns-preview   # Preview only

Or manually:

export GANDI_PERSONAL_ACCESS_TOKEN=$(op read "op://vg6xf6vvfmoh5hqjjhlhbeoaie/mco6ka3dc3rmw7zkg2dhia5d2m/pat")
pulumi up
