I am trying to communicate with two pods with two different namespace and different service?

CodePudding user response：

Two pods in different namespaces communicate via the domain name of the service. In your case if pod A (service A) wants to connect to pod B (service B) in namespace blue, it would need to connect to b-service.blue or the full name of

b-service.blue.svc.cluster.local

CodePudding user response：

As long as you have created a service to front the pods (NodePort, ClusterIP or LoadBalancer), you can access the pods using the format

{name of service}.{namespace}.svc.cluster.local

So if the service you are trying to access resides in the namespace redis and is called redis-standlone, you would access it like this:

redis-standalone.redis.svc.cluster.local
