antrea/antrea-mc-controller repository overview

Antrea is a Kubernetes⁠ networking solution intended to be Kubernetes native. It operates at Layer 3/4 to provide networking and security services for a Kubernetes cluster, leveraging Open vSwitch⁠ as the networking data plane.

Antrea can provide networking and security functions across multiple K8s clusters. In particular, Antrea implements the Multi-cluster Service API⁠, which allows users to create multi-cluster Services that can be accessed cross clusters in a ClusterSet. Antrea Multi-cluster also extends Antrea-native NetworkPolicy to support Multi-cluster NetworkPolicy rules that apply to cross-cluster traffic, and ClusterNetworkPolicy replication that allows a ClusterSet admin to create ClusterNetworkPolicies which are replicated across the entire ClusterSet and enforced in all member clusters.

Multicluster support is dependent on the deployment of the Antrea Multicluster Controller, in each cluster belonging to the ClusterSet.

This image is specific to the amd64 architecture. It is meant to be run as a Deployment in a K8s cluster.
