Create CodeDeploy

#codedploy #aws #cloud #devops

  • AWS CodeDeploy is a fully managed deployment service that automates software deployments to a variety of compute services such as Amazon EC2, AWS Fargate, AWS Lambda, and your on-premises servers.

  • AWS CodeDeploy makes it easier for you to rapidly release new features, helps you avoid downtime during application deployment, and handles the complexity of updating your applications.

  • You can use AWS CodeDeploy to automate software deployments, eliminating the need for error-prone manual operations. The service scales to match your deployment needs.

1. Install codedeploy-agent on EC2 target machine 

aws s3 ls --recursive s3://aws-codedeploy-ap-northeast-1 --region ap-northeast-1 aws s3 cp s3://aws-codedeploy-ap-northeast-1/latest/install . sudo yum update sudo yum install ruby cd /home/ec2-user aws s3 cp s3://aws-codedeploy-ap-northeast-1/latest/install . chmod +x ./install sudo ./install auto systemctl status codedeploy-agent.service ● codedeploy-agent.service - AWS CodeDeploy Host Agent Loaded: loaded (/usr/lib/systemd/system/codedeploy-agent.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2020-10-30 02:27:22 UTC; 1 months 25 days ago Main PID: 4788 (ruby) Tasks: 6 Memory: 92.6M CGroup: /system.slice/codedeploy-agent.service ├─4788 codedeploy-agent: master 4788 └─4794 codedeploy-agent: InstanceAgent::Plugins::CodeDeployPlugin::CommandPoller of master 4788

2. Create S3 bucket to store application package (.zip) which contains deployment scripts and appspec.yml for codedeploy service consumes 

version: 0.0 os: linux files: - source: / destination: /var/www/html/WordPress hooks: BeforeInstall: - location: scripts/install_dependencies.sh timeout: 300 runas: root AfterInstall: - location: scripts/change_permissions.sh timeout: 300 runas: root ApplicationStart: - location: scripts/start_server.sh - location: scripts/create_test_db.sh timeout: 300 runas: root ApplicationStop: - location: scripts/stop_server.sh timeout: 300 runas: root

3. Create Lambda function which listen to S3 event of the above bucket and then create deployment

4. Create codedeployment application and Deployment groups to consume app package

create.sh

# Create application aws deploy create-application --application-name myapp --compute-platform Server --region ap-northeast-2 # Create group deployment aws deploy create-deployment-group --application-name myapp --deployment-group-name mygroup --ec2-tag-filters Key=Name,Value=dev,Type=KEY_AND_VALUE --service-role-arn arn:aws:iam::111111111111:role/CodeDeployServiceRole --deployment-style deploymentType=IN_PLACE,deploymentOption=WITHOUT_TRAFFIC_CONTROL --region ap-northeast-2
Enter fullscreen mode Exit fullscreen mode

5. Push package to S3 bucket in order to trigger deploy

  • Note: Custom object metadata should be prefixed with x-amz-meta-. For example, x-amz-meta-application-name or x-amz-meta-deploymentgroup-name. Amazon S3 uses this prefix to distinguish the user metadata from other headers. 
zip -r demo.zip appspec.yml scripts/ aws s3 cp demo.zip s3://codedeploy/demo.zip --metadata x-amz-meta-application-name=myapp, x-amz-meta-deploymentgroup-name=mygroup

  • Result
