KubeVirt to deploy and manage VMs on Kubernetes
Managing infrastructure with both containers and traditional Virtual Machines (VMs) can be complex. While Kubernetes has transformed container management, many organizations still rely on VMs for legacy applications or compliance. This often leads to disorganized management tools and added complexity for DevOps teams, often resulting in silos and difficulties in scaling infrastructure.
KubeVirt addresses these challenges that DevOps teams face. It helps manage VMs alongside containers in Kubernetes. This allows users to use the same tools and processes for both. In this blog, I will show you how to deploy and manage VMs on Kubernetes using KubeVirt. I will cover the installation steps, create VMs, set up persistent storage, and provide an example that connects traditional virtualization with modern container management.
Prerequisites
Before we begin, we must have:
- A running Kubernetes cluster. We can set up a cluster using tools like minikube or any other Kubernetes provider
- kubectl configured to manage our Kubernetes cluster.
- Basic familiarity with Kubernetes concepts like pods, deployments, and services.
Steps to setup KubeVirt
First, we will select the latest version of KubeVirt and set the environment variable KUBEVIRT_LATEST_VERSION for future commands.
KUBEVIRT_LATEST_VERSION=$(curl -s https://api.github.com/repos/kubevirt/kubevirt/releases/latest | awk -F '[ \t":]+' '/tag_name/ {print $3}')Install KubeVirt with latest version
This command sets up a “kubevirt” namespace, installs Custom Resource Definitions for KubeVirt, and configures an operator to start the KubeVirt installation when a configuration resource is detected.
kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${KUBEVIRT_LATEST_VERSION}/kubevirt-operator.yamlNow Here We will be adding the Kubevirt Custom Resource (named kubevirt). This will prompt the KubeVirt operator to install the…..Read More
