Kubernetes Cluster Automation with Kops and LAMP Stack Deployment

This repository contains a bash script that automates the process of creating a Kubernetes cluster using kops and deploying a LAMP (Linux, Apache, MySQL, PHP) stack application.

Prerequisites

Before running the script, make sure you have the following tools installed and configured:

• AWS CLI
• kubectl
• kops

Additionally, ensure you have:

• An AWS account with appropriate permissions.
• A domain managed in Route 53 or a subdomain.

Script Overview

The script performs the following steps:

1. Checks for prerequisites.
2. Creates an S3 bucket for kops state storage.
3. Creates a Kubernetes cluster with kops.
4. Creates a namespace.
5. Deploys a MySQL database.
6. Deploys a PHP application using Apache.
7. Exposes the PHP application.
8. Verifies the deployments.
9. Optionally, cleans up resources.

Usage

1. Clone the repository or save the script to a file, e.g., kops_deploy_lamp.sh.

2. Make the script executable:

   chmod +x kops_deploy_lamp.sh

3. Update the script variables at the top of the script with your own values, such as CLUSTER_NAME, STATE_BUCKET, ZONE, etc.

4. Run the script:

   ./kops_deploy_lamp.sh

5. To clean up the cluster after verification, uncomment the delete_cluster function call at the end of the script.

Script Variables

• CLUSTER_NAME: The name of the Kubernetes cluster.
• STATE_BUCKET: The name of the S3 bucket for storing kops state files.
• KOPS_STATE_STORE: The S3 bucket URL for kops state storage.
• NODE_COUNT: The number of nodes in the cluster.
• NODE_SIZE: The instance type for the nodes.
• MASTER_SIZE: The instance type for the master node.
• ZONE: The AWS availability zone.
• NAMESPACE: The namespace for deploying the applications.

Verification

After running the script, the MySQL database and the PHP application will be deployed, and the PHP application will be exposed via a LoadBalancer. You can verify the deployment by checking the status of the pods and services:

kubectl get pods -n <namespace>
kubectl get services -n <namespace>
