Sync Nebula Host Names to Netlify DNS

Template repo for syncing your Defined Networking host names to Netlify DNS records via the API.

See the accompanying blog post: https://www.defined.net/blog/dns-for-nebula-hosts-using-the-api/

Setup

1. Click Use this template and set your new repo's visibility to Private — scheduled workflows in public repos are disabled automatically after 60 days without activity.
2. Add DN_API_KEY and NETLIFY_TOKEN as repository secrets.
3. Set DOMAIN (and optionally SUBDOMAIN) in .github/workflows/sync-dns.yml.
4. Uncomment the schedule trigger in .github/workflows/sync-dns.yml — it ships commented out so the sync doesn't run before your secrets are configured.
