Bootstrapping AWS CDK Automation With Amazon CodeCatalyst
A step-by-step on establishing an AWS CDK setup alongside Amazon CodeCatalyst, enabling the creation of a comprehensive CI/CD pipeline for your infrastructure.
A step-by-step guide on establishing an AWS CDK setup alongside Amazon CodeCatalyst from the ground up, enabling the creation of a comprehensive CI/CD pipeline for your infrastructure.
AWS CDK is fantastic for overseeing your entire infrastructure as code, but when multiple developers are involved in modifying the infrastructure, the situation can become chaotic without a proper mechanism like a CI/CD pipeline. Absence of such a system makes coordinating and communicating changes to the infrastructure a challenging task, and this challenge amplifies as more individuals participate in the modification process.
This tutorial will guide you through setting up a CI/CD pipeline using Amazon CodeCatalyst and AWS CDK for building To-Do web application
Setting up a CodeCatalyst Project, Repo, and Environment
Login to CodeCatalyst and go to your Space (Create one if you don't have)
Create a project from scratch
Create repository to store code and workflows of the project
Create CICD Environments which associates to AWS account for deploying our infrastructure
Create IAM role for codecatalyst to consume during running workflows. It should be already created while you create the Space or you can customize the others
Design workflows
Workflows directory
Workflows is triggered by PUSH of branch main and includes following Actions
Actions
FrontendBuildAndPackage - Build react app, target build which is shared to cross-actions by Artifacts of Outputs
FrontendTest Test frontend code
CDKBootstrapAction - Run cdk bootstrap for the region of the account with latest CDK version. This action depends on FrontendTest and FrontendBuildAndPackage
CDKDeploy - Download build target of FrontendBuildAndPackage and trigger cdk deploy, this action depends on CDKBootstrapAction. Here I don't use the defined action aws/cdk-deploy@v1 of CodeCatalyst because I'd like to use projen and pnmp in CDK and handle copying frontend target build
Use EC2 compute type for CodeCatalyst workflows
Source code and CDK stacks
Structure
cdkStack Define CDK stacks and use projen for configuration management as well as pnpm
frontend Frontend react app
Push source code to repo
Init the repo and add repo URL which is created from the above as origin
Workflows Runs
When the commit is pushed to the main branch, CodeCatalyst CI/CD triggers the workflows
The CDKDeploy triggers cloudformation to create AWS resources
After the workflows done, we now have the To-Do Web app UI
Conclusion
Congratulations! You've successfully bootstrapped and initialized AWS CDK with CodeCatalyst, and you can now deploy infrastructure changes or update frontend/backend using a pull request workflow.
