This Makefile exposes commands to do a manual deploy to AWS Elastic Beanstalk using the AWS CLI. Normally, you would do a deploy with the `eb` command, but using the AWS CLI is more convenient for orchestrating continuous deployment from a CI server.

circle.yml

deployment:
  production:
    branch: master
    commands:
      - make deploy

Run make deploy after changing the variables to match your project to run a deploy. The circle.yml file can be used with CircleCI to do continuous deployment when a branch passes.
