Details

• CI Part: dockerfile

  • Multistage build, separate build image and runtime image
  • Script run_dockerfile，dynamicly call docker build by rendering parms from pom.xml for 'Dockerfile'
  • Unit test：with github action，trigger at push event and PR open

• Infrastructure: AWS CDK

  • Creating VPC，Cluster，TaskDefinition，LogGroup，FargateService etc. for Serverless
  • Creating Metric，SNS Topic,Alarm with cloudwatch to send warnning email

• CD Part:

  • Setting applcation name and version in infra/app.py (CDK Usage)
