This page describes the compatibility matrix of Contour and Kubernetes versions.
Contour utilizes client-go to watch for resources in a Kubernetes cluster.
Since Kubernetes is backwards compatible with clients, older client-go versions will work with many different Kubernetes cluster versions.
client-go package includes a compatibility matrix as to what Kubernetes API versions are supported with the version of client-go.
It’s important to note that since Contour consumes a small number of quite stable Kubernetes APIs, most Kubernetes versions most likely will not have issues, however, the client-go package does not guarantee compatibility.
If you are using a Kubernetes distribution offered by a public cloud provider, where you don’t have the option to upgrade to a more recent and supported Kubernetes version (as per the support matrix outlined below), please talk to us on Slack or attend a community meeting. We would like to find a way to satisfy your use case with Contour.
