Becoming a DevOps pro: Using Terraform and Jenkins to unleash the power of REST API deployment on AWS

Mastering DevOps means unleashing the magic of deploying a REST API on AWS using Terraform and Jenkins. It’s like performing a symphony on a grand stage, where Terraform is the conductor, Jenkins is the soloist, and AWS is the orchestra. Each piece comes together in harmony, creating a masterpiece that dazzles the audience! 🎶🌟

Getting Started with Terraform ✨

We’ll start off by setting up the entire project using Terraform. The pipeline for deploying a REST application with a database onto an EC2 instance will be created. We’ll be managing our services and setting up a Python REST API on GitHub. This is the initial stage of setting up the infrastructure manager and working with Jinja. We will move further by setting up the VPC, which acts as a boundary for managing data.

Setting Up the VPC 🚀

We will already have the VPC set up and a closer look will be taken at the file group to understand how the installation takes place. We will also be configuring the machine over the code and utilizing resources from AWS.

Provisioning Subnets and EC2 Instances 🛠️

We will be going through the process of creating subnets and EC2 instances in the AWS West region using Terraform. The second subnet will be created and we’ll be associating the public and private subnets. The Code Security IP Suite will be uploaded.

"Every action we take inside infrastructure is important for the resource provisioning."

Managing EC2 Instances with Terraform ⚠️

We will be provisioning an EC2 instance and a security group while diving into requests to and from the instance. This will be done using the Terraform commands, ensuring proper port configuration and defining the security group.

• Instance Type: EC2
• Port: 8080

Integrating Jenkins with AWS 📦

The Jenkins instance will be utilized by creating an AMI and associating it with the public subnet. Later, the AMI will be tagged and an SSH key will be generated to access the EC2 instance.

Once the instance is set up, we can proceed with the configuration of Jenkins.

Setting Up the Load Balancer and Route53 🌐

We will be creating a logical load balancer and associating the target group instances with it. Furthermore, we will define the target port and the health check settings for the load balancer. Finally, we’ll set up the hosted domain and the DNS server records using Route53.

• Port: 8080
• Target Group: Jenkins
• HTTPS: Enabled

Deploying REST API with Terraform 💡

In this step, we will be deploying a REST API and a Flask application. After running the code, we’ll update the repository and wait for the application to be deployed. We’ll be configuring the EC2 port and hosting the application on the subdomain.

Accessing the MySQL Database 🔑

We will utilize the MySQL database to store the data of our REST project. We’ll be creating the schema, connecting to the database, and executing the pipeline to destroy the entire project.

"It’s important to have the entire project down to the last detail to ensure the example is clear for all."

Conclusion 📝

In conclusion, deploying a REST API on AWS with Terraform and Jenkins involves multiple steps, starting from VPC setup to database management. Each stage requires careful consideration and proper configuration to ensure a seamless deployment process. With the right tools and techniques, deploying a REST API becomes a manageable task.

Key Takeaways:

• Leveraging Terraform and Jenkins for project deployment
• Managing VPC and EC2 instances effectively
• Configuring load balancers and Route53 for domain management
• Using MySQL database for storing project data

FAQ: Is it necessary to use Jenkins for REST API deployment?

Yes, Jenkins simplifies the deployment process by providing automation and continuous integration benefits. Its integration with AWS ensures efficient project deployment.
