Agreed.

Application runtime dependencies are a common source of communication breakdowns between development and infrastructure teams. Making the application container a maintained build file on the project improves this communication.

docker provides:

* a standard format for building container images (the Dockerfile)

* a series of optimizations for working with images and containers (immutable architecture etc).

* a community of pre-built images

* a marketplace of hosting providers

All at the cost of linux only, which is ok for many shops.
