Deploying Kubernetes(k8s) Single Node Cluster Using VMware vRealize Automation (VRA)8

Deployment Steps: –

1. Create VM Template and Map Template to VRA Image Mapping: –

In vSphere, create a VM, Install the Operating System, and Convert the VM to a Template.

Log in to vRealize Automation (VRA), Select Cloud Assembly Service, create a new Image map and select template as REDHAT_8.6.

You can check my Previous post – How to Create Image mapping –

1. Import Blueprint to VRA using Cloud Assembly Service and Release Blueprint: –

Open Cloud Assembly Service

Download the Cloud Assembly code file from the following URL – https://github.com/Dineshk1205/VRAK8s/blob/main/Redhat8.yaml Upload.

Update Configuration based on your Infra. Version and Release Blueprint Item to Catalog.

1. Import Pipeline Code, Enable, and Release Pipeline: –

Import Pipeline.

Import operation type create, Update project name according to your environment. Import.

1. ADD Variables to VRA Code Stream: –

In Code Stream, Add REDHAT VM Template Username and Password.

1. Publish Code Stream Pipeline to VRA Service Catalog Items: –

Enable imported pipeline and Release.

In Service Broker, Add Code Type Code Stream Pipeline. Save & Import.

You can Pipeline imported. You can click on three dots and customize Pipeline Form & Configuration item.

In the Definitions, create new or add content to existing definition items.

1. Request K8s Deployment Using VRA Service Catalog: –

Request Catalog item k8sSingleNode.

, Enter the Deployment name, Select Project Kubernetes Version(1.26 or 1.25), Calico_CNI_VERSION, and CRI-O_ContainerRuntime_Version (You also Create a Drop-down option using the Custom forms option).

Submit.

Wait a few minutes. Once Deployment is completed. Check Deployed Node IP.

Use Putty or any other tool. SSH to the node using the above IP. Check Node status and POD Status.
