Building a CI/CD Pipeline with AWS CodePipeline

To build a CI/CD pipeline in AWS, follow these steps:

1. Source: Set up a source repository such as AWS CodeCommit, GitHub, or Bitbucket to store your code and trigger pipeline execution when changes occur.
2. CodeBuild: Create a CodeBuild project and define the specifications in a buildspec.yml file. This step compiles and tests the code.
3. CodeDeploy: Set up AWS CodeDeploy (or other deployment services like Amazon ECS, Elastic Beanstalk, or Lambda) to deploy your application to your desired environment (e.g., staging or production).
4. CodePipeline: Create a CodePipeline to automate the flow between source, build, and deploy stages. This links the services and ensures continuous integration and deployment.
5. Test the CI/CD Pipeline: After setting up the pipeline, push code changes to the repository and verify that the pipeline triggers the build, test, and deployment automatically.

To run AWS CodePipeline:

1. Create a pipeline in the AWS Management Console by defining stages like source, build, and deploy.
2. Link it to a version control system like AWS CodeCommit or GitHub for the source, integrate build tools like AWS CodeBuild for building your code, and specify deployment services like AWS Elastic Beanstalk or Amazon ECS.
3. Once configured, AWS CodePipeline automatically manages the process of code changes moving through the pipeline, including building, testing, and deploying your application
