Securing communication ports

To ensure secure transmission of network traffic to and from the Cloud Pak for Data cluster, you need to configure the communication ports used by the network.

Cluster ports

The primary port is what the Red Hat® OpenShift® router exposes. See Configuring and managing cluster networking for Red Hat OpenShift Container Platform 4.6, Configuring and managing cluster networking for Red Hat OpenShift Container Platform 4.5, or Network Access Requirements for Red Hat OpenShift Container Platform 3.11 for details.

Ports for services

When you provision a new service or integration on your Cloud Pak for Data cluster, the services might require connections to be made from outside the cluster. For example, you might require connections when you access databases, or run data virtualization through an ODBC/JDBC connection. If the service or integration requires connections to be made to the cluster, locate the port numbers from each service's Details page and open those network ports. Each port is TCP, and randomly allocated between the 30000-32767 range.
