Dockerfiles use a simple DSL which allows you to automate the steps you would normally manually take to create an image.

The built-in orchestration features announced today with Docker 1.12 will revolutionize how IT teams build, ship and run containerized apps. With Docker 1.12, developers and ops now share a set of simple and powerful APIs, tools, and formats for building agile delivery pipelines that ship software from development through CI to production in the cloud with Docker for AWS and Azure. To facilitate that revolution, we’re introducing Distributed Application Bundles—an experimental open file format for bundling up all the artifacts required to ship and deploy multi-container apps: a DAB contains a description of all the services required to run the application and details images to use, ports to expose, and the networks used to link services. Once you start using the service feature to run replicated, distributed, and load balanced services on Docker 1.12 swarms (or if you’ve used Docker…

Docker monitoring of servers and containers is becoming necessary the more
Docker hosts and containers we provision. This tutorial will walk you through
how to glue together several different components in order to achieve Docker
monitoring.

Components for Docker Monitoring
First things first. We assume that Docker is installed, configured, and running
on your host before we begin. Please ensure you can connect to your Docker host
with a Web Browser either locally or over a Public IP. The rest
