Aws Codepipeline | Aws Developer Tools

1. Introduction

AWS CodePipeline is a fully managed continuous delivery service that helps automate the build, test, and deploy phases of your release process. By using AWS CodePipeline, developers can rapidly and reliably deliver features and updates. This service is critical for DevOps practices as it improves the speed and quality of software releases.

2. AWS CodePipeline Services or Components

CodePipeline is composed of several key components:

Source Stage: This is where the code is pulled from a source repository like AWS CodeCommit, GitHub, or Bitbucket.
Build Stage: This stage compiles the code, runs tests, and produces build artifacts using services like AWS CodeBuild.
Test Stage: Automated tests are run to validate the application using testing frameworks.
Deploy Stage: The final stage where the application is deployed to environments such as AWS Elastic Beanstalk, Amazon EC2, or Amazon ECS.

3. Detailed Step-by-step Instructions

Here’s how to set up a simple pipeline:

Step 1: Create a new pipeline using AWS CLI.

aws codepipeline create-pipeline --cli-input-json file://pipeline.json

Step 2: Define your pipeline structure in the pipeline.json file.
