Gitlab Pipeline With AWS Codedeploy

Flow Chart

1. Create Codedeploy

• Follow the link to create lambda function which is trigger by S3 notification event and then create code deployment.
• Gitlab pipeline job will push deploy.zip to S3 so that lambda function will create code deployment for running install script on target instance by codedeploy-agent

2. Gitlab pipeline jobs to build and deploy

• image_version.txt is packed in deploy.zip for codedeploy get version to deploy
• Codedeploy structure:
  • application: service_name (app, api, myweb, etc.)
  • deployment group: branch_name (feature, develop, hotfix, master, integration, etc.), each one will have same or different target instancce
• .gitlab-ci.yml
