Despite using automated deploys for most things I work on I had put off setting up such a mechanism for this site. Not sure what took so long.

With CircleCI I added a circle.yml file of:

dependencies:
  override:
    - pip install -r requirements.txt

test:
  override:
    - make build

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

And then an S3 user with the right permissions.

            ]
        }
    ]
