OCP Network Prerequisites

Portworx network requirements

Portworx runs as a pod in a Kubernetes cluster and uses specific ports for communication, data transfer, and telemetry.

East-to-west

note

Portworx also requires the following ports:

• An open KVDB port. For example, if you're using etcd externally, open port 2379.
• An open UDP port at 17002.
