Using Aws Rds With Codebuild

Introduction

In this guide, we will demonstrate how to set up an AWS RDS instance and integrate it with AWS CodeBuild using Pulumi. AWS RDS (Relational Database Service) is a managed relational database service that supports several database engines, while AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages.

Step-by-Step Explanation

Step 1: Set Up AWS RDS Instance

1. Create a new Pulumi project: Initialize a new Pulumi project if you haven’t already.
2. Install the necessary Pulumi packages: Ensure you have the AWS Pulumi provider installed.
3. Define the RDS instance: Use Pulumi to define and create an RDS instance with the desired configuration.

Step 2: Set Up AWS CodeBuild Project

1. Define the CodeBuild project: Use Pulumi to define a CodeBuild project that will use the RDS instance.
2. Configure the buildspec file: Ensure your buildspec file includes the necessary steps to interact with the RDS instance.

Step 3: Deploy the Infrastructure

1. Run pulumi up: Deploy the defined infrastructure using Pulumi.
2. Verify the deployment: Check the AWS Management Console to ensure the RDS instance and CodeBuild project are set up correctly.

Summary

By following this guide, you have successfully set up an AWS RDS instance and integrated it with AWS CodeBuild using Pulumi. This setup allows you to leverage managed database services in your CI/CD pipelines, ensuring a robust and scalable development workflow.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create an RDS instance
const rdsInstance = new aws.rds.Instance("my-rds-instance", {
    allocatedStorage: 20,
    engine: "mysql",
    engineVersion: "8.0",
    instanceClass: "db.t2.micro",
    name: "mydatabase",
    username: "admin",
    password: "password",
    skipFinalSnapshot: true,
});

// Create a service role for CodeBuild
const codebuildRole = new aws.iam.Role("codebuild-role", {
    assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({
        Service: "codebuild.amazonaws.com",
    }),
});

// Attach the necessary policies to the role
const codebuildRolePolicyAttachment = new aws.iam.RolePolicyAttachment("codebuild-role-policy-attachment", {
    role: codebuildRole.name,
    policyArn: "arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess",
});

// Create a CodeBuild project
const codebuildProject = new aws.codebuild.Project("my-codebuild-project", {
    source: {
        type: "GITHUB",
        location: "https://github.com/my/repo",
    },
    environment: {
        computeType: "BUILD_GENERAL1_SMALL",
        image: "aws/codebuild/standard:4.0",
        type: "LINUX_CONTAINER",
        environmentVariables: [
            {
                name: "DB_HOST",
                value: rdsInstance.endpoint,
            },
            {
                name: "DB_USER",
                value: "admin",
            },
            {
                name: "DB_PASS",
                value: "password",
            },
        ],
    },
    serviceRole: codebuildRole.arn,
    artifacts: {
        type: "NO_ARTIFACTS",
    },
});

export const rdsEndpoint = rdsInstance.endpoint;
export const codebuildProjectName = codebuildProject.name;
