digitalocean-registry-cleanup

DigitalOcean operations skills. DNS zones: domain/record CRUD via doctl and the DigitalOcean Terraform provider, apex CNAME / no-flattening trap when migrating from Cloudflare, FQDN trailing-dot semantics, DNS-01 ACME wildcard certs, nameserver delegation. App Platform: lints app specs (app.yaml / doctl apps spec JSON / digitalocean_app Terraform) for plaintext secrets, missing health checks, single-instance services, dev databases in production, port mismatches, overlapping ingress routes, conflicting git/image sources, deprecated routes, unknown instance sizes, and app/database region mismatch. Container Registry: analyze and clean registry images — list repos with tag counts, delete old tags (keep last N), find stale repos, trigger garbage collection, with dry-run support.
