To deploy your Spring Boot application in an AWS environment using Terraform and host the endpoint while keeping the Terraform code in a separate GitHub repository with environment-specific configurations, you can follow the steps outlined below. This setup will allow you to use Infrastructure as Code (IaC) to manage your AWS resources and easily deploy your Spring Boot application.
- Prerequisites Ensure that the following tools are installed and set up:
Spring Boot: Your application ready for deployment (packaged as a JAR or Docker container). Terraform: Installed on your local machine (https://www.terraform.io/downloads.html). AWS Account: Active AWS account with programmatic access (AWS CLI configured with access and secret keys). Docker (optional): If deploying your Spring Boot app as a Docker container. GitHub Account: Where you’ll keep your Terraform code in a separate repository. 2. Set up Your Spring Boot Application Make sure your Spring Boot application is packaged and ready for deployment. You can either deploy it directly as a JAR or as a Docker container.
a. Packaging Your Spring Boot App (JAR) bash Copy code ./mvnw clean package This will create a target/your-app-name.jar file.
b. Dockerizing Your Spring Boot App If you prefer to use Docker, create a Dockerfile in your Spring Boot project:
dockerfile Copy code FROM openjdk:11-jdk-slim VOLUME /tmp COPY target/your-app-name.jar app.jar ENTRYPOINT ["java","-jar","/app.jar"] Then build the Docker image:
bash Copy code docker build -t your-docker-image . 3. Create Terraform Scripts for AWS Infrastructure In a separate GitHub repository (e.g., springboot-terraform-deployment), create Terraform scripts to define your AWS infrastructure. Below is an outline of the key components.
a. Folder Structure for Terraform Repository css Copy code springboot-terraform-deployment/ ├── main.tf ├── variables.tf ├── outputs.tf └── environments/ ├── dev.tfvars ├── prod.tfvars └── staging.tfvars b. main.tf – Define AWS Resources This file will define the infrastructure components for your application. It typically includes:
VPC EC2 instance or Elastic Beanstalk (to host the app) Security groups IAM roles (if needed) S3 bucket (for app storage, logging, etc.) RDS instance (if using a database) Elastic Load Balancer (if scaling) IAM for access and permissions
Create a policy with below data points:
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "iam:PassRole", "Resource": "arn:aws:iam::accountNumber:role/vinod" }, { "Effect": "Allow", "Action": [ "ecs:CreateCluster", "ecs:RegisterTaskDefinition", "ecs:ListClusters", "ecs:DescribeClusters", "ecs:ListTaskDefinitions", "ecs:DescribeTaskDefinition", "ec2:CreateVpc", "ec2:DescribeVpcs", "ec2:DeleteVpc", "ec2:CreateSubnet", "ec2:DescribeSubnets", "ec2:DeleteSubnet", "ec2:CreateRouteTable", "ec2:DescribeRouteTables", "ec2:DeleteRouteTable", "ec2:CreateInternetGateway", "ec2:DescribeInternetGateways", "ec2:DeleteInternetGateway", "ec2:AttachInternetGateway", "ec2:DetachInternetGateway", "ec2:CreateTags" ], "Resource": "arn:aws:ec2:us-east-1:accNumber:vpc/*" } ] }
An enhanced architecture that incorporates Terraform for infrastructure management, Jenkins for CI/CD, and Kubernetes for microservices deployment on AWS. Here's a high-level
overview of the architecture: Infrastructure Management with Terraform: Use Terraform to define and manage AWS resources including VPC, subnets, security groups, EKS cluster, and EC2 instance for Jenkins. Jenkins Installation: Deploy Jenkins on an EC2 instance using Terraform. Configure Jenkins with necessary plugins for AWS, Kubernetes, and pipeline management. Kubernetes (EKS) Cluster: Set up an Amazon EKS cluster using Terraform to host microservices. CI/CD Pipeline: Use Jenkins to create pipelines that build, test, and deploy microservices to the EKS cluster. Microservices: Deploy microservices as containers in the EKS cluster. Here's a textual representation of the enhanced architecture: text [Terraform] | ├── Manages | | | ├── [VPC, Subnets, Security Groups] | | | ├── [EC2 Instance] | | └── [Jenkins Server] | | | └── [EKS Cluster] | └── [Kubernetes] | └── [Microservices] | └── Deploys | └── [Jenkins Server] | └── CI/CD Pipelines | └── Deploy to EKS
This architecture allows you to: Manage all AWS infrastructure as code using Terraform. Use Jenkins for continuous integration and deployment. Deploy microservices to a scalable Kubernetes environment on AWS EKS. Maintain a clear separation between infrastructure management, CI/CD processes, and application deployment. To implement this, you would: Write Terraform scripts to set up the AWS infrastructure, including the EKS cluster and Jenkins EC2 instance. Use Terraform to install and configure Jenkins on the EC2 instance. Set up Jenkins pipelines to build and deploy your microservices to the EKS cluster. Deploy your microservices as Kubernetes deployments in the EKS cluster. This setup provides a robust, scalable, and manageable architecture for deploying microservices on AWS using modern DevOps practices.
