I have a private cloud network (using k8s with istio) and i want to access legacy service on a legacy network.
I want to use mTLS to authentificate pod from k8s and allow it to access legacy service.
How can i do that ?
I thinking about creating a new k8s cluster on the legacy network with istio enabled and create an ingress gateway in it. The goal is that the pod on the cloud will talk to the istio ingress gateway in the legacy network (so we can authentificate and authorize the access to the service in legacy network).
What i don’t know is that: is the istio ingress gateway in the legacy network can forward the traffic to legacy services. And if yes how can i do it ?
