Replaces the self-signed dev cert flow with a real LE prod cert for dns.l.supported.systems, issued and auto-renewed by a Caddy sidecar using DNS-01 challenge against the Vultr API. Components: - caddy/Dockerfile builds Caddy 2.10.0 with caddy-dns/vultr plugin via xcaddy. GOTOOLCHAIN=auto so xcaddy can fetch newer Go on demand when plugin versions advance their minimum Go. - caddy/Caddyfile uses DNS-01 with explicit public resolvers (1.1.1.1, 9.9.9.9) for the propagation check. Without that, Docker's embedded DNS leaks the container into the host's split-horizon LAN DNS, which returns LAN IPs for ns1.vultr.com and the propagation check fails. - docker-compose: caddy service shares ./caddy-data with coredns via a read-only subpath mount that excludes /acme (account private key). - Healthcheck doubles as a symlinker: maintains stable cert.pem / key.pem names at /data/caddy/ and chmods cert files + their dirs to be readable by CoreDNS's nonroot user. Flips to "healthy" only once the symlinks dereference (i.e. cert exists), gating CoreDNS start via depends_on: service_healthy. - Corefile unchanged — same /etc/coredns/certs/cert.pem path; only the bind-mount source switches from ./certs to ./caddy-data/caddy. - New Makefile target: tls-up orchestrates the bring-up sequence. Cert is valid until Aug 12 2026. Verified end-to-end: dig @127.0.0.1 -p 8853 +tls +tls-hostname=dns.l.supported.systems ... dig @127.0.0.1 -p 8443 +https +tls-hostname=dns.l.supported.systems ...
