Infrastructure in Code - DockerFiles and Docker Compose

Abstract:

The growth in Virtualisation and Containers is helping us replace a lot of our network infrastructure with discrete, ephemeral components and micro-services.

In this presentation I will introduce you to a DockerFile, a way of describing an individual container, a set of commands for creating a Container. This will specifically cover:

• Finding existing Docker images to use and extending them
• Triggering commands on a container
• Setting environment variables
• Exposing ports that a container may need
• Copying files to a container
• Submitting your own images to the Docker hub

I will demonstrate how DockerFiles can be supplemented with Docker Compose to create complex, inter-connected application stacks that can be created, deleted and updated with simple one-line commands. I will specifically cover:

• Compose equivalents to DockerFile options
• Linking containers
• Selecting local or remote images
