Following table shows the port requirements for the Kubernetes operator deployment. If firewalls exist between the various hosts, you must open the required communication ports.
Table: Ports that must be open in a NetBackup Kubernetes cluster environment
Source | Port number | Destination |
|---|---|---|
Primary server | TCP port 443 | Kubernetes cluster |
Media server | TCP port 443 (new in NetBackup 10.0). | Kubernetes cluster |
Note: Review the Kubernetes configuration to ensure that the Kubernetes API server port has not been changed from 443 to a non-default port; often 6443 or 8443. | ||
Kubernetes cluster | TCP port 443 (applicable in NetBackup version 9.1, but not in version 10.0 or later). | Primary server |
Note: NetBackup Kubernetes Operator (KOps) and datamover pods have additional requirements (new in NetBackup 10.0). | ||
Kubernetes cluster | TCP port 1556 outbound | Primary server |
Kubernetes cluster | TCP port 1556 outbound | Media server |
Kubernetes cluster | TCP port 13724 bi-directional if using Resilient Network. | Primary and media server |
