Summary

TLDRABI from gokjdb guides viewers through deploying a serverless AWS SAM application using AWS CodeBuild and AWS CodePipeline. The tutorial covers creating a repository, setting up a serverless project with the Python runtime, configuring and deploying the application, and verifying deployment through an API Gateway URL. It also explains creating a buildspec.yml file, setting permissions for the service role, and automating the deployment process with a pipeline that responds to code changes, culminating in a demonstration of updating the application and redeploying.

Takeaways

  • ๐Ÿ“ Start by creating a repository in AWS Code Commit and cloning it locally.
  • ๐Ÿ› ๏ธ Use the AWS SAM (Serverless Application Model) CLI to create a new serverless project with Python as the runtime.
  • ๐Ÿ”„ Choose 'Create from existing sources' and allow time for project files to be generated.
  • โš™๏ธ Configure the project using the 'hello world' template and run it to ensure it works.
  • ๐Ÿš€ Execute 'sam build' and 'sam deploy --guided' to deploy the application and follow the prompts for configuration.
  • ๐Ÿ”— After deployment, check the logs for the API Gateway endpoint URL and verify the application by accessing it.
  • ๐Ÿ“„ Create a 'buildspec.yml' file necessary for deploying the application with AWS CodeDeploy.
  • ๐Ÿ”„ Commit and push all project files to the Code Commit repository.
  • ๐Ÿ—๏ธ Set up a build project in AWS CodeBuild, specifying the source, branch, and operating system.
  • ๐Ÿ‘ฎโ€โ™‚๏ธ Add necessary permissions to the service role for access to AWS services like S3, CloudWatch, API Gateway, CloudFormation, and Lambda.
  • ๐Ÿ”„ Initiate the build process and monitor the logs for success or errors.
  • ๐Ÿ”„ Create a pipeline in AWS CodePipeline, linking it to the source and build projects.
  • ๐Ÿ”„ Make changes to the application, commit, and push to trigger the pipeline's automated build and deployment process.
  • ๐Ÿ”„ Monitor the pipeline and build logs to confirm successful deployment of changes.

Q & A

  • What is the main topic of the video?

    -The main topic of the video is how to deploy a serverless AWS SAM (Serverless Application Model) application using AWS CodeBuild and AWS CodePipeline.

  • What is the first step mentioned in the script for deploying a serverless application?

    -The first step is to navigate to the CodeCommit service, create a new repository, and clone it to the local machine using 'git clone'.

  • Which tool is used to create a new AWS serverless project?

    -The tool used to create a new AWS serverless project is the AWS SAM CLI (Command Line Interface).

  • What runtime is chosen for the serverless project in the video?

    -Python is chosen as the runtime for the serverless project.

  • What template is selected in the configuration for the SAM application?

    -The 'Hello World' template is selected as the input for the SAM application configuration.

  • What command is used to build the SAM application in the terminal?

    -The command used to build the SAM application is 'sam build'.

  • What does 'Sam deploy --guided' do in the script?

    -'Sam deploy --guided' is used to follow the prompts and set the configuration for the SAM deployment.

  • What file is created for deploying the application using CodeDeploy?

    -A 'buildspec.yml' file is created, which is needed when deploying the application using CodeDeploy.

  • What service role is mentioned in the script, and why is it important?

    -The service role mentioned is important because it needs to have permissions to access AWS services like S3, CloudWatch, API Gateway, CloudFormation, and Lambda for the deployment process.

  • What is the purpose of creating an AWS CodePipeline?

    -The purpose of creating an AWS CodePipeline is to automate the deployment process by integrating source control, build, and deployment stages.

  • How does the video script demonstrate updating the application?

    -The script demonstrates updating the application by editing the 'app.py' file, changing the output message, committing the change, and pushing it to the remote master branch to trigger a new pipeline execution.
