Kubernetes-native container networking implementation providing CNI connectivity and NetworkPolicy security for pod workloads.
Antrea is an open-source, Kubernetes-native project that implements the Container Network Interface and Kubernetes NetworkPolicy. It provides network connectivity and security for pod workloads, making Kubernetes network policies usable for enforcing isolation and access control across a cluster.
Antrea originated at VMware, and antrea.io documentation covers its use with VMware Tanzu Kubernetes clusters. Provider context for the project is traced to Broadcom following its acquisition of VMware.
