Quick example

Example config.toml

backends = [
    { address = "backend-a:9000", http_version = "preserve" },
    { address = "backend-b:9000", http_version = "preserve" },
]

routes = [
    { prefix = "/api", backend = "backend-a:9000", fingerprinting = true, force_new_connection = false },
    { prefix = "/", backend = "backend-b:9000" },
]

preserve_host = false

[listen]
addrs = ["0.0.0.0:7000", "[::]:7000"]

[tls]
cert_path = "/config/certs/server.crt"
key_path = "/config/certs/server.key"
alpn = ["h2", "http/1.1"]
watch_delay_secs = 60

[fingerprint]
tls_enabled = true
http_enabled = true
tcp_enabled = true

[telemetry]
metrics_port = 9090

Adjust hostnames (backend-a, backend-b) and paths to match your Compose service names or local backends. For TLS, point cert_path / key_path at real files (or use plain HTTP by omitting [tls] during local tests).

Observability

With telemetry.metrics_port set, health and metrics are on that port, not the main listener:

• GET /health, GET /ready, GET /live, GET /metrics
