Finding the internal URLs for IBM Streams services

If your IBM® Streams applications run within the Kubernetes cluster, you will get the best performance if you use the Kubernetes internal host and port to form the URL to access the Streams service.

To find the internal host and port for the Streams service, you must find the Kubernetes object name, namespace, and internal port.

1. View a list of Kubernetes services that were created by using the following command:

   kubectl get svc -n <namespace>

   For example, for the Kubernetes services in a namespace called mynamespace, where the Streams instance is called myinstance, the build service is called mybuild, and the security service is called mysecurity, you will see the following output:

   $ kubectl get svc -n mynamespace
   NAME                                TYPE        CLUSTER-IP       EXTERNAL-IP                PORT(S)                         AGE
   mybuild-build                   NodePort    192.0.2.0        <none>                     8445:30720/TCP                  21d
   mysecurity-sso                  NodePort    192.0.2.1        192.0.2.15,192.0.2.16      8446:31682/TCP                  21d
   myinstance-console              ClusterIP   192.0.2.2        <none>                     9000/TCP                        21d
   myinstance-jmx                  NodePort    192.0.2.3        192.0.2.17                 9975:30555/TCP,9976:31076/TCP   21d
   myinstance-management           ClusterIP   192.0.2.4        <none>                     9000/TCP                        21d
   myinstance-repository           ClusterIP   192.0.2.5        <none>                     9000/TCP,9001/TCP               21d
   myinstance-security             ClusterIP   192.0.2.6        <none>                     9000/TCP                        21d
   myinstance-sws                  NodePort    192.0.2.7        192.0.2.18                 8443:31794/TCP                  21d  

2. Use the output and the following table to determine the host and port for the Kubernetes service for the Streams service that you want to access.

   Table 1.

   Service	Host	Port
   Streams console and Streams instance REST APIs	<instance-name>-sws	8443
   Streams build service	<build-service-name>-build	8445
   Streams security service	<security-service-name>-sso	8446
