By | May 16, 2018

In this article, we will integrate NSX-T NCP and CNI to Openshift.

Step 01: Tag the Logical Switches Ports connected to OCP-Master, OCP-Node01 and OCP-Node02 VMs.

Step 02: On the master Node, lets fork the NSX-T Integration for Openshift. The below is using Yasen github, but its a fork from the actual nsxt integration from here -> https://github.com/vmware/nsx-integration-for-openshift.

On every node, run this
cd /root/nsx-container-2.1.3.8356796/Kubernetes
docker load -i nsx-ncp-rhel-2.1.3.8356796.tar

On all the 3 nodes, you have to do the following.

 docker images
 docker tag registry.local/2.1.3.8356796/nsx-ncp-rhel nsx-ncp
 docker images

Then on the master,
cd /root
cd /root/nsx-integration-for-openshift/openshift-ansible-nsx/roles/ncp_prep/defaults/
nano main.yml
change the uplink_port to ens224
# update the variable values below before running the ncp_prep role
