Grafana is no longer publicly accessible. It's now only reachable at https://grafana.internal for clients connected to the WireGuard VPN. - Add stacks/traefik/conf.d/internal.yml with VPN-only routes for grafana.internal and glowroot.internal (served with mkcert wildcard cert) - Mount overlays/wireguard/certs/ into stacks/traefik so certs are shared between the wireguard and traefik compose projects - Fix wireguard overlay incompatibilities with multi-instance approach: use bind-mount for certs instead of named volume, change network from `frontend` to `proxy`, remove orphaned traefik service override that referenced the now-deleted single-instance dynamic.yml - Add service definitions to overlays/wireguard/traefik/internal.yml (grafana-internal → monitoring-grafana:3000, glowroot-internal → app:4000) - Remove stacks/traefik/conf.d/monitoring.yml.template and the start-monitoring Makefile step that generated it (public Grafana route) - Remove GRAFANA_HOSTNAME from monitoring .env.template and generate script; hardcode GF_SERVER_ROOT_URL=https://grafana.internal in docker-compose.yml - Gitignore overlays/wireguard/certs/ and config/ (contain private keys) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds wireguard-proxy service that listens on 10.8.0.1:443 (wg0 IP) inside the WireGuard container's network namespace and forwards to traefik:443. Docker DNS resolves 'traefik' per connection, so it handles Traefik container restarts without needing hardcoded IPs or iptables DNAT rules. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Unreferenced near-duplicate of stacks/traefik/conf.d/internal.yml, which is the file Traefik actually loads.
`make get-vpn-ca` writes the root CA to the working tree so clients can install it; it should not land in commits.
The mkcert container that writes the key and the Traefik container that reads it both run as root, so the key does not need to be world-readable.
The `domain: "*.internal"` env var was never consumed: the compose file overrides the image entrypoint with `command: sh /mkcert.sh`, and the script hardcodes the two host names. The generated cert is already a 2-SAN cert, not a wildcard.
Sweep em dashes out of files added or modified on this branch. Pre-existing em dashes in master (README intro and footer) are left alone as out of scope.
The vishnunair/docker-mkcert image only publishes a `latest` tag, so pinning by digest is the only stable reference available.
Previously mkcert.sh produced a single 2-SAN cert (grafana.internal + glowroot.internal) shared by both routes. Switch to one cert per host and list both in Traefik's tls.certificates so SNI selects the right one. Existing deployments must clear the wireguard-certs volume to drop the old internal.crt/internal.key on first run after this change.
Replaces the pinned vishnunair/docker-mkcert digest with a minimal custom Dockerfile that fetches mkcert directly from the upstream release URL, removing the dependency on a third-party image.
