Ingress control is a core concept in Kubernetes, that is implemented by a third party proxy. Contour is a Kubernetes ingress controller that uses the Envoy edge and service proxy. Tanzu Kubernetes Grid includes signed binaries for Contour and Envoy, that you can deploy on Tanzu Kubernetes clusters to provide ingress control services on those clusters.
IMPORTANT: Due to significant improvements in the mechanism to deploy extensions in Tanzu Kubernetes Grid 1.2, it is strongly recommended that you upgrade to Tanzu Kubernetes Grid 1.2 before attempting to deploy any extensions.
For general information about ingress control, see Ingress Controllers in the Kubernetes documentation.
