Kong

Kong ships a Kubernetes ingress controller implementation which translates Ingress resources into Kong configuration. In this configuration a Kong cluster is created within the cluster.

Installation

Installation is either via Kubernetes manifests or a Helm chart (kong, in https://charts.konghq.com).

Configuration

Kong's configuration is managed by the Kong operator, which monitors the various CRDs:

• KongIngress is an extension resource that stores Kong-specific configuration, associated with either an Ingress or Service resource:
  • When associated with an Ingress all routes associated with the Ingress resource are updated using each KongIngress.route.
  • When associated with a Service all services and upstreams in Kong are updated using each KongIngress.proxy and KongIngress.upstream.
• KongPlugin resources configure plugins against Ingress, Service, and KongConsumer resources. They're namespace scoped.
• KongClusterPlugin is a non-namespaced KongPlugin.
• KongConsumer configures Kong consumers.
• TCPIngress allows exposing non-HTTP and non-gRPC services.
• KongCredential is deprecated in favour of Secret.
