eve-bridge is a CNI plugin for Kubernetes which allows to connect Pod with EVE Network Instances. This CNI plugin establishes Pod connectivity in cooperation with the zedrouter microservice. A CNI request received from Kubernetes to connect Pod to a given network instance is delegated by eve-bridge to zedrouter via an RPC call over an AF-UNIX socket. More details can be found in the documentation submitted under pkg/kube/eve-bridge/README.md Signed-off-by: Milan Lenco <milan@zededa.com>
