Combination of Cilium Golang Envoy Filter and TCP tunnel to build Visual Studio Bridge To Kubernetes.

example/overview.png

Why rebuild Bridge To Kubernetes?

The current version of Bridge To Kubernetes has some limitations, for example:

  1. Can't have multiple pods behind a k8s service.
  2. Can't have multiple container in a pod.
  3. Can't have TLS between pods.

And these limitations can solved by the help of CNI.
