Fields

name: String

backends: Vec<String>

strategy: String

health_check: Option<HealthCheckConfig>

tls: bool

true when all backends use https:// scheme — connections to the upstream are made over TLS. Requires the http-client or http2 feature (which bring in rustls + webpki-roots).

tls_ca_file: Option<String>

tls_ca_file — PEM file of CA certificates to trust for this upstream’s https:// backends instead of the public WebPKI roots (a private CA or a self-signed certificate). None = WebPKI.

tls_client_cert_file: Option<String>

tls_client_cert_file / tls_client_key_file — a client certificate (PEM chain and key) presented to TLS backends that require one. Since 18.3.0.

tls_client_key_file: Option<String>

weights: Vec<u32>

weights — one per backend, in order (default 1 each). Since 18.6.0.

sticky: Option<StickyConfig>

[upstream.sticky] — keep a client on one backend. Since 18.6.0.

circuit_breaker: Option<BreakerConfig>

[upstream.circuit_breaker] — take failing backends out of rotation (passive health checks). Since 18.6.0.

retry: Option<RetryConfig>

[upstream.retry] — try another backend. Since 18.6.0.
