I have a gcp cluster with api services and I was using ambassador 1.9 for edge routing. Now we have decided to upgrade the ambassador to 2.3.2. So I follow the steps in ambassador docs for upgradation by parallelly running both ambassador versions. But after the process is finished the backend service is unhealthy, making the ingress down.
- Multiple deployments with corresponding services.
- Ambassador Edge Stack as API gateway
- Ingress for exposing the edge stack service
I'm a beginner in both ambassador and stackoverflow, so please let me know if more details are needed.
