Erich Blume 005e2a03ed C0: split gandi-operations docs; add dns-acme-cleanup mise task 
Splits the nebulous gandi-operations how-to into two single-topic cards
(manage-eblu-me-dns, rotate-gandi-pat) and adds a mise task for the
recurring _acme-challenge TXT cleanup needed due to a value-comparison
bug in libdns/gandi v1.1.0 that prevents certmagic's cleanup phase from
removing presented TXT values.

The gandi reference card is updated to drop the false "different
credential from Pulumi PAT" claim — verified during the 2026-04-27
incident that Caddy and Pulumi share a single PAT.

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 uses a Gandi Personal Access Token (PAT) shared with Caddy. See the Gandi reference card and Rotate the Gandi PAT.

The mise tasks handle fetching the PAT from 1Password:

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

Or manually:

export GANDI_PERSONAL_ACCESS_TOKEN=$(op read "op://blumeops/gandi - blumeops/pat")
pulumi up

DNS Records Created

Record Type Value Purpose
*.ops.eblu.me A (indri's Tailscale IP) Wildcard for all services
ops.eblu.me A (indri's Tailscale IP) Base subdomain
