  • Question: Describe the steps you took to set up the CI/CD pipeline in Jenkins.
    • Expected Answer: A detailed explanation of the setup process, including installing Jenkins, configuring the pipeline, integrating with version control, and setting up automated build and deployment steps.
    • Sample Answer: "I started by installing Jenkins on an AWS EC2 instance.

Finally, I set up the deployment step to push the Docker image to AWS ECR and deploy it to an ECS cluster using Terraform scripts."
  • Question: How did you use Terraform to manage the infrastructure for the deployment?
    • Expected Answer: Explanation of creating Terraform scripts to define the infrastructure, using modules for reusability, and applying the scripts to provision resources.
    • Sample Answer: "I wrote Terraform scripts to define the AWS infrastructure, including VPC, subnets, security groups, ECS cluster, and load balancer. I used Terraform modules to organize the code and ensure reusability. I then applied the scripts using Terraform CLI to provision the resources in AWS."
  • Question: How did you ensure the reliability and scalability of the deployment?
    • Expected Answer: Discussion of monitoring tools, scaling strategies, and best practices for maintaining reliability.‍
