DevOps Project 3
In this blog, I will demonstrate, how to make a ci-cd pipeline using GitHub, Jenkins, Terraform, Helm, & Amazon EKS.
Suppose, you are a DevOps engineer or cloud ops engineer in your company, and your lead or manager asks you to create a ci-cd pipeline that can create an EKS cluster in AWS and after creating the cluster, pipeline should install some applications in it using Helm.
Follow the below steps:
Step1: Create a EC2 instance in AWS and install Jenkins. you will find the installation guide in the below link.

Step 3: Create an S3 bucket for storing your terraform state file.
Step 4: Replace the bucket name with the above one in the backend.tf file.
Step 5: Create a freestyle project in Jenkins, and configure it with git, shell script, and parameters. you will find the shell script in the below repo.
PARAMETERS:
REGION : aws region
VPC_ID : aws vpc id
CLUSTER_NAME : eks cluster name
ACTION : terraform apply or destroy

Step 6: Create an IAM role and attach an admin policy to it. after creating, you have to attach the IAM role to the Jenkins server.
Step 7: We have set up everything for this project, and now we can run our Jenkins job. you can take the help of the below video for guidance.
