- Add server module that orchestrates the full startup sequence:
parse config, init dynamic config, init shared state, bind health
check, bind admin socket, bind all listener ports, load TLS config,
start TCP listeners, start background tasks, signal readiness
- For each ListenerConfig: bind TCP listener, construct appropriate
ServerConfig (manual or ACME via TlsMode), create TlsAcceptor
- ConnectInfo<SocketAddr> populated from TcpStream::peer_addr() BEFORE
TLS wrapping via ConnectInfoService wrapper that inserts ConnectInfo
into request extensions for each connection
- Per-listener axum::Router instances sharing Arc<ProxyState> via State
- Fail-fast: if any bind or TLS load fails, exit with non-zero code
- All ports bound before any connections accepted
- /health endpoint available on HTTPS listener(s) as fallback
(proxy_router already includes /health route)
- sd_notify(READY=1) sent after all listeners started
- Use hyper_util for TLS connection serving with TowerToHyperService
and ConnectInfoService to bridge ConnectInfo from pre-TLS peer_addr
- Add sd-notify dependency for systemd readiness notification
- Add Cli struct with clap derive macros for --config, --validate, --allow-wildcard-bind flags
- Config loading: reads TOML, deserializes into StaticConfig + DynamicConfig, validates
- --validate: load, validate, print success/errors, exit 0 or 1
- --allow-wildcard-bind is OR'd with config allow_wildcard_bind field
- Default config path: /etc/reverse-proxy/config.toml
- Version from Cargo.toml via clap
- Unit tests for CLI argument parsing and config loading
- Integration tests for --validate with valid/invalid config and --allow-wildcard-bind
- Add [lib] target to enable integration test imports
- Add rcgen and reqwest dev-dependencies for TLS and HTTP test helpers
- Create src/config/test_fixtures.rs with test_static_config() and test_dynamic_config()
- Create tests/ with integration tests, HTTP test helper (TestUpstream), and TLS test helper (SelfSignedCert)
- Add Clone derives to StaticConfig and related structs for test fixture construction
- All existing tests continue to pass
