The docker-compose stack now serves Headscale (and its embedded DERP)
over TLS on port 8443 with a self-signed cert covering localhost,
127.0.0.1, and the docker-network hostname `headscale`. Tailscale
peers trust the cert via SSL_CERT_FILE; our test daemon uses
`derp_tls_insecure: true` (gated on the SUNBEAM_NET_TEST_DERP_INSECURE
env var) since pinning a self-signed root in tests is more trouble
than it's worth.
With TLS DERP working, the previously-ignored
`test_e2e_tcp_through_tunnel` test now passes: the daemon spawns,
registers, completes a Noise handshake over TLS, opens a TLS DERP
relay session, runs a real WireGuard handshake with peer-a (verified
via boringtun ↔ tailscale interop), and TCP-tunnels an HTTP GET
through smoltcp ↔ engine ↔ proxy ↔ test client. The 191-byte echo
response round-trips and the test asserts on its body.
- tests/config/headscale.yaml: tls_cert_path + tls_key_path, listen on
8443, server_url=https://headscale:8443
- tests/config/test-cert.pem + test-key.pem: 365-day self-signed RSA
cert with SAN DNS:localhost, DNS:headscale, IP:127.0.0.1
- tests/docker-compose.yml: mount certs into headscale + both peers,
set SSL_CERT_FILE on the peers, expose 8443 instead of 8080
- tests/run.sh: switch to https://localhost:8443, set
SUNBEAM_NET_TEST_DERP_INSECURE=1
- tests/integration.rs: drop the #[ignore] on test_e2e_tcp_through_tunnel,
read derp_tls_insecure from env in all four test configs
Spins up Headscale 0.23 (with embedded DERP) plus two Tailscale peers
in docker compose, generates pre-auth keys, and runs three integration
tests behind the `integration` feature:
- test_register_and_receive_netmap: full TS2021 → register → first
netmap fetch
- test_proxy_listener_accepts: starts the daemon and waits for it to
reach the Running state
- test_daemon_lifecycle: full lifecycle including DERP connect, then
clean shutdown via the DaemonHandle
Run with `sunbeam-net/tests/run.sh` (handles compose up/down + auth
key provisioning) or manually via cargo nextest with the env vars
SUNBEAM_NET_TEST_AUTH_KEY and SUNBEAM_NET_TEST_COORD_URL set.
