If you are building software applications in the AWS cloud, you may need a tool to automate the deployment process from commit to production. AWS CodePipeline, a managed service, helps you to build, test, and deploy your code changes continuously. In this tutorial, we’ll cover the basic functionality of CodePipeline, and show you how to create a simple pipeline that deploys a sample application from Github to an EC2 instance.
Before creating a pipeline, you should prepare your application source code, version control system, and deployment steps. CodePipeline works with multiple source code repositories including Github, AWS CodeCommit, and BitBucket. It also integrates with other AWS services such as CodeBuild, CodeDeploy, and Lambda, as well as third-party tools such as Jenkins and Git.
To create a pipeline, follow these steps:
Assuming you have an EC2 instance running, you can create an EC2 deployment stage by following these steps:
To test the pipeline, make a code change in your source repository, and commit the changes. CodePipeline will automatically pick up the changes, trigger the build process, and when that completes successfully, deploy the code to your target deployment environment.
After the pipeline completes, you can view the pipeline history, see the execution status, and troubleshoot any errors that arise during the process.
AWS CodePipeline is a powerful tool that enables you to create a continuous integration and continuous deployment (CI/CD) pipeline for your software applications. By automating the software delivery process, teams can focus on developing new features and improving product quality, while reducing the risk of human error during deployments.
