Containerize It!: An Introduction to Docker

This will be a demonstration-focused introduction to Docker (https://www.docker.io/), a rapidly growing open source project for packaging, distributing, and running applications as containers (think lightweight, OS-level virtualization). Docker was open sourced in March 2013 and quickly has become one of the most popular projects on GitHub (currently the 32nd most starred project). It is written in Go and is maintained by Docker, Inc., formerly dotCloud, Inc. along with a community of over 400 contributors.

In this presentation, we will walk through the basics of Docker, including working with images and containers, using the public image repository, handling image versioning, and some of the capabilities of the docker command line tool. Additionally, we will go through the process of creating a simple Dockerfile, the recipe format for Docker images. The Dockerfile will be used to demonstrate deploying an application on AWS Elastic Beanstalk with their recently added support for Docker containers. We will then discuss use cases and current applications of Docker in the industry.

    ryan, forgot to ask about if docker imposes a certain file system inherited from the host. in other words, does the union file system run in a production container? i suppose i could just create a container to answer my question!

      Sorry John, not sure what you mean by "production container". If you try out what you're thinking, let us know.

      Thanks for joining last night!
