OpenShift Container Platform

Creating additional ports for node pools

You can configure additional ports for node pools for hosted clusters that run on Red Hat OpenStack Platform (RHOSP).

Prerequisites

You created a hosted cluster.
You have access to the management cluster.
The hcp CLI is installed.
Additional networks are created in RHOSP.
The project that is used by the hosted cluster must have access to the additional networks.
You reviewed the options that are listed in "Options for additional ports for node pools".

Procedure

Create a hosted cluster with additional ports attached to it by running the hcp create nodepool openstack command with the --openstack-node-additional-port options. For example:
```
$ hcp create nodepool openstack \
  --cluster-name <cluster_name> \
  --name <nodepool_name> \
  --replicas <replica_count> \
  --openstack-node-flavor <flavor> \
  --openstack-node-additional-port "network-id=<sriov_net_id>,vnic-type=direct,disable-port-security=true" \
  --openstack-node-additional-port "network-id=<lb_net_id>,address-pairs:192.168.0.1-192.168.0.2"
```
where:

<cluster_name>

Specifies the name of the hosted cluster.

<nodepool_name>

Specifies the name of the node pool.

<replica_count>

Specifies the number of replicas that you need.

<flavor>

Specifies the RHOSP flavor to use.

<sriov_net_id>

Specifies a SR-IOV network ID.

<lb_net_id>

Specifies a load balancer network ID.
