VM Configuration

In this guide, we’ll walk through provisioning a DevSecOps Cloud virtual machine, installing essential DevSecOps tools, and configuring a single-node Kubernetes cluster. This setup is perfect for learning CI/CD, containerization, and Kubernetes orchestration.

Prerequisites

Azure CLI ≥ 2.20 or GCP SDK
Vagrant & VirtualBox (for local testing)
Basic Linux shell proficiency

VM Specifications

Specification	Details
Operating System	Ubuntu 20.04 LTS
vCPUs	4
Memory	16 GB RAM
Ingress Firewall	All traffic (demo only)

The firewall rule allowing all inbound traffic is for demonstration only. Do not use such permissive settings in production environments.

Provisioning the VM

Azure Resource Manager Template

Use the provided ARM template and parameters:

# Create a resource group
az group create \
  --name DevSecOpsRG \
  --location eastus

# Deploy the VM
az deployment group create \
  --resource-group DevSecOpsRG \
  --template-file azuredeploy.json \
  --parameters @azuredeploy.parameters.json

Google Cloud Platform (gcloud) Commands

Or spin up a GCP instance:

gcloud compute instances create devsecops-cloud \
  --zone=us-central1-a \
  --machine-type=n1-standard-4 \
  --image-family=ubuntu-2004-lts \
  --image-project=ubuntu-os-cloud \
  --tags=http-server,https-server

Local VirtualBox Deployment (Vagrant)

For local testing with Vagrant:

# Start the VM
vagrant up --provider=virtualbox

Software Installation

SSH into your VM and run the installer:

ssh ubuntu@<VM_PUBLIC_IP>
git clone https://github.com/yourrepo/devsecops-vm-setup.git
cd devsecops-vm-setup
chmod +x install.sh
./install.sh

Installation Breakdown

Component	Version	Purpose
Docker CE	Latest	Container runtime
kubeadm, kubelet, kubectl	v1.21.x	Kubernetes cluster tools
OpenJDK	8	Jenkins runtime
Maven	3.6.x	Java build automation
Jenkins LTS	2.xx.x	Continuous Integration server

The install.sh script updates packages, installs Docker CE, sets up Kubernetes tools, initializes a single-node cluster, and deploys Jenkins.

Cluster Configuration

Enable pod scheduling on the master node:

kubectl taint nodes --all node-role.kubernetes.io/master-

Verify node readiness:

kubectl get nodes
