phases:

    commands: 
      - echo Logging in to Amazon ECR...

    commands: 
      - echo Build started on `date` 
      - echo Building the Docker image... 
      - docker build -t $REPOSITORY_URI:latest . 
      - docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:$IMAGE_TAG

    commands: 
      - echo Build completed on `date` 
      - echo Pushing the Docker images... 
      - docker push $REPOSITORY_URI:latest

      - printf '[{"name":"nodeapp","imageUri":"%s"}]' $REPOSITORY_URI:$IMAGE_TAG > imagedefinitions.json 
      - cat imagedefinitions.json  
artifacts: 
    files: imagedefinitions.json 

This requires that the assigned build role have permissions for ECR. Will also create an imagedefinitions.json for participation in CodePipeline
