  • Question

    I have recently registered with the free Azure trial. Previously, I have created a small minikube application. Services are deployed with ClusterIP and can communicate with each other using the  <service>.default.svc.cluster.local DNS domain. I have managed to get the 

    One thing that I am struggling to understand is how services within Microsoft Kubernetes communicate with each other.

    For example, assuming that there are two services, A and B, deployed inside a cluster deployed at .....

    If service A wants to communicate/address service B what DNS name should it use?

    Does Azure Kubernetes Service (AKS) allow ClusterIP?

    Kind Regards

  • Yes, the DNS name will work exactly the same, as per: https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/
    Communication is happens through the service name and AKS does allow clusterIP.
    If Service A is called "hello" and Service B is called "world". Service A would be able to ping, make requests to DNS name "world".
