I recently saw a tweet from Jason Shiplett who works over on the VMware Validated Design (VVD) team (also my former team before joining VMware Cloud) who shared a new validated design for running Redhat OpenShift 4.3 on VMware Cloud Foundation. Funny enough, a couple of days ago I was just researching into deploying OpenShift running on VMware Cloud on AWS from a customer inquiry.
Timing could not have been better as RedHat just announced their OpenShift 4.5 release a few days ago as and one of the major updates is support for vSphere using their full stack automation also known as te Installer Provisioned Infrastructure (IPI) option. Previous to this, customers who wanted to deploy OpenShift on vSphere had to use the User Provisioned Infrastructure (UPI) method, which the VVD design also uses, which is much lengthier and complex when compared to the native IPI method.
For someone who has never worked with OpenShift before, this was great news and I get to try out this new deployment method on an VMware Cloud on AWS infrastructure 🙂
Step 1 - You will need a Linux system to perform the installation and it should have access to the vCenter Server running in VMware Cloud on AWS (VMC). In my example, I am using an Ubuntu Server 20.04 VM which is also running in the SDDC and has outbound internet connectivity.
Step 2 - Login to VMware Cloud on AWS console and create a new NSX-T network segment that is DHCP enabled. In my example, I named it openshift-network with a 192.168.3.0/24 configuration.
