What this PR does / why we need it:
This PR implements a "replacement" of a Garden service (or a few services) running in a k8s cluster with a locally deployed application (or a few applications).
In order to achieve this, the target container in the k8s cluster is replaced with a proxy container that runs an ssh server. First, the Garden app starts an SSH tunnel between the local service and the proxy container using
kubectl port-forwardcommand. Next, it starts a reverse-port-forwarding withsshbetween the remote proxy container's exposed port and the local app's port withsshcommand.The Garden supports the new
local-modeoption indeploycommand and the newlocalModeconfiguration entry. It allows running a Garden service in "local mode". It means running the application locally and connecting it to the k8s cluster via a proxy container.See running-service-in-local-mode.md for more details.
See local-mode example to try it out.
