Developing Ruby Applications with Docker
summary
Claims Docker can supplant hypervisor VMs for Ruby apps and demonstrates concrete tooling and workflow: building images with a Dockerfile, pushing and finding 15,000 images on Docker Hub, composing services with Docker Compose and provisioning with Docker Machine. A Rails app gets built, run, edited via a volume mount, linked to an official Postgres container, migrations run via docker-compose run, and the demos start and serve pages successfully from the containerized environment.
