"Dockerise" the application

[johnboyes]

• [ ] Ensure the application works locally on a docker image
• [ ] Use Docker as much as possible for the CI (looks like Circle 2.0 uses Docker out of the box so there might not be much/anything to be done here)
• [ ] Use Docker as much as possible for the CD
• [ ] Push the image to Docker Hub?
• [ ] Deploy it on Digital Ocean?
