Peering with calico bgp in Google GKE
Is there a way that I can peer a BGP speaker in a pod with the calico install in a GKE cluster with network policy enabled?
We are trying to set up a L3 routing solution for sending traffic to a pod that maintains a TAP interface with a private subnet for delivering packets to remote clients similar to a VPN.
We can create a route for this subnet manually on the k8s nodes with the pod IP as the next hop, and the traffic flows successfully thanks to calico's IpIp mesh. However, calico/node deletes my manual routes shortly after they're created.
We were planning to deploy a DaemonSet of bird instances to the cluster, and adding a bird container to the VPN pod. Then peer the pod's instance with the k8s node's bird instance to handle dynamic route propagation as the pod is created/destroyed.
Because calico grooms the route entries, this isn't going to work. So we're looking for a way to peer with GKE's calico/node or to keep it from removing entries that were created outside of it.
