Contour GatewayClass API

Cluster-scoped resources that define the controller responsible for managing Gateways of a particular class. GatewayClass is analogous to IngressClass in the legacy Ingress API.

Contour HTTPProxy API

Operations for managing Contour HTTPProxy custom resources in a Kubernetes cluster. HTTPProxy resources define ingress routing rules for HTTP and HTTPS traffic.

Contour HTTPRoute API

Namespace-scoped resources that define HTTP routing rules, mapping HTTP/HTTPS requests to backend Kubernetes services based on host, path, headers, and other criteria.

Contour TLSCertificateDelegation API

Operations for managing TLSCertificateDelegation resources that allow certificates in one namespace to be used by HTTPProxy resources in other namespaces.

Contour TLSRoute API

Namespace-scoped resources that define TLS routing rules for routing TLS connections based on SNI hostname to backend services.
