Terraform, Ansible, and Jenkins DevOps Project for EC2 Provisioning Automation
Automate EC2 provisioning and server configuration with Terraform, Ansible, and Jenkins.
This DevOps project walks through a practical infrastructure automation workflow where Jenkins triggers Terraform to provision AWS resources and Ansible finishes the configuration of the new instance. It is a strong project for learners who want to demonstrate infrastructure as code and configuration management together.
Project overview
The workflow starts with Jenkins parameters that control whether infrastructure should be created or destroyed. Terraform provisions the EC2 instance and stores state remotely, while Ansible configures the server after it becomes reachable. Together, these steps model a realistic automation pattern used in many DevOps teams.
What you will build
- A Jenkins job with reusable infrastructure parameters
- Terraform provisioning for AWS EC2 resources
- Remote Terraform state handling with S3
- Ansible configuration steps for application setup after provisioning
Core implementation steps
- Create Jenkins parameters for actions like apply and destroy
- Attach the correct IAM role so Jenkins can work with AWS resources
- Use Terraform to create the EC2 instance and supporting resources
- Run Ansible after the instance is ready to install and configure software
Common mistakes to avoid
- Using overly broad IAM permissions in production environments
- Running Ansible before the instance is fully reachable
- Forgetting to configure the S3 backend for Terraform state
- Allowing destroy flows to trigger unnecessary configuration tasks
Why this project is valuable for SEO and traffic
- People frequently search for Terraform and Ansible project examples they can actually build
- The topic attracts readers preparing for DevOps roles and automation interviews
- Practical EC2 automation content can rank well because it solves a specific real-world task
FAQ
Is Terraform enough without Ansible for this project?
Terraform can create the infrastructure, but Ansible adds post-provision configuration, which makes the project more realistic and useful.
Why use Jenkins in this setup?
Jenkins provides repeatability, parameter handling, and job history so the full automation flow can be triggered consistently.
Is this a good project for a DevOps resume?
Yes. It shows infrastructure as code, automation thinking, AWS usage, and configuration management in one workflow.
