 In this video, we'll look at the ease of installation of OpenShift version 3 environment, specifically we'll look at how easy it is to spin up new nodes. For creating a new node, all I did is I, this is an OpenStack based environment. My OpenShift is installed on OpenStack. I spun up a new host, a virtual machine on OpenStack. I called it node 3 and I registered that system with Red Hat and all I did was ran a script to enable all the dependencies that OpenShift requires. So my, what you're seeing here is the node 3 that is just spun up and it's running on OpenStack and it is ready to get installed as a node on master. Now let me go back to the master and I'll show you some of the changes I made to the hc ansible hosts file. All I needed to do here to add node 3 was add this one line and this line says that I want to add an additional node which is node3.demov3.occloud.com and I'm saying this node should be added with labels configured as the region as primary and the zone should be vest. We already had two nodes in the region primary. Node 1 was configured as zone vest and node 2 was configured as zone east. Now I'm adding a node 3 and that would be configured as zone vest. I am also passing an additional parameter. This is just for the sake of OpenStack. I'm saying that the OpenShift public host name is node3.demov3.occloud.com and the OpenShift host name also I'm passing the same value. Now this is the only change I need to make to the configuration file that ansible takes as an input. Now let me run the ansible playbook to install the node3. All I have to do is execute this one command and it'll run a bunch of scripts. This will take a couple of minutes so I'll run it a little faster and it is done. As you can see it added node3 and it also reconfigured the master to say that node3 is ready. So you can see that it has changed two different things. Now let us look at what nodes are now available and the node3 is ready. So it is as simple as running this one script to make changes to the OpenShift environment to add additional nodes. This shows you how easy it is to install OpenShift. Now this kind of a process can be handled by external tools like CloudForms or it can also be integrated and automated into OpenStack scripts and which is going to come up in the future if you happen to use OpenStack and OpenShift together.
