Overview:

This project deploys a multi-tier application on a Kubernetes cluster using kops. The application consists of the following components:

• vproapp: Backend service
• vprodb: MySQL database
• vpromc: Memcached service
• vprormq: RabbitMQ service

Prerequisites:

Before you begin, ensure you have the following installed:

• kubectl: Kubernetes command-line tool
• kops: Kubernetes Operations tool
• AWS CLI configured with appropriate permissions
• Access to an AWS S3 bucket for storing Kubernetes cluster state

Steps:

1. Create Kubernetes Cluster:

   Use kops to create a Kubernetes cluster on AWS:

   kops create cluster --name=mycluster.k8s.local --state=s3://k8s-bucket --zones=us-east-1a,us-east-1b --node-count=2 --node-size=t3.small --master-size=t3.medium --dns-zone=mycluster.k8s.local --node-volume-size=8 --master-volume-size=8
   
   kops update cluster --name mycluster.k8s.local --state=s3://k8s-buket --yes --admin
   

2. Validate The Cluster

   Make Sure To Check For The Cluster's Health

   kops validate cluster --name mycluster.k8s.local --state=s3://kops-state-2024

3. Create an EBS Volume On AWS For The Database:

   Using AWS CLi

   aws ec2 create-vloume --availability-zone=us-east-1a --size=3 --volume-type=gp2

4. Tag The Volume With The Following Tag:

   KubernetesCluster = mycluster.k8s.local

5. Label The Node In The Same Zone As The Volume:

   Using kubectl

   kubectl label node <node-name> zone=us-east-1a

6. Change The Volume ID

   Update The Vloume ID in DB/vprodb-deploy.yml With Your Volume ID

7. Deploy The App:

   Using kubectl

   kubectl apply --recursive -f .

8. Clean Up

   When You're Done Make Sure To Destroy The Cluster To Avoid Extra Charges

   kubectl delete --recursive -f .
   
   kops delete cluster --name  mycluster.k8s.local --state=s3://kops-bucket --yes

Notes

• Replace "mycluster.k8s.local" with your cluster's DNS name.
• Replace "k8s-bucket" with S3 bucket name.
• Ensure your AWS credentials are configured correctly.
