Under the hood of Docker Containers

Under the hood of Docker Containers

FOSDEM 2015

Docker containers are generating excitement because of relatable and recognizable use cases and unique facilitation of solutions. One example of this is easy distribution of the container environment. Docker does this with a particular design of images.

In this talk, we will discuss:

• Storage of Docker images: the drivers available as well as some of best practices and recommended performance tunings.
• Notes on the format: how a Docker image is at rest on a daemon versus a registry, and how the image is transferred.
• Verification of images: mechanics of validation and how to return reproducible sums

The goal of this talk is to provide greater awareness of options available for daemon setup, knowledge around the bits in-flight daemon-to-registry, and assurance of this data.
