The Mixed Version Proxy (MVP) enhances Kubernetes cluster upgrades by safely routing requests for unknown resources to newer API servers, preventing 404 errors. Initially introduced as an Alpha feature in Kubernetes 1.28, MVP is now moving to Beta in version 1.36 and will be enabled by default. MVP addresses the issue of API servers with differing versions during upgrades, where requests for new resources might fail on older servers. Instead of the incorrect 404, the request is proxied to a server capable of handling it. The Beta version of MVP uses aggregated discovery instead of the StorageVersion API for determining peer capabilities, improving functionality. This update also includes peer-aggregated discovery, providing clients with a unified view of all available APIs. To enable MVP, API servers require the --peer-ca-file flag, along with --peer-advertise-ip and --peer-advertise-port if needed. With kubeadm, you can include those flags in your ClusterConfiguration file to streamline the process. Users are encouraged to test MVP in staging environments and provide feedback to the SIG API Machinery as part of the 1.36 upgrade.
