Push a Docker DAB to a Kubernetes Cluster in Two Commands!

Docker Distributed Application Bundles (DABs) are "an experimental open file format for bundling up all the artifacts required to ship and deploy multi-container apps." DABs contain a complete description of all the services required to run an application, along with details about which images to use, ports to expose, and networks used to link services.

A little over a month ago, I wrote about DABs and outlined how they can be used with multi-tier apps to develop locally with Docker Compose and then bundled for deployment to a Docker Swarm cluster.

In this post, I will expand on my previous post and show how DABs can be used to make an artifact that is deployable on a Kubernetes cluster.

Why? Because by doing this we can take advantage of the awesome develop experience that the Docker tools provide to deploy artifacts to a production-ready Kubernetes cluster without needing a whole bunch of Kubernetes experience. Win win.

Note: DAB files are still experimental as of Docker 1.12.
