This series of posts describes how we can generate smaller Docker images. In the first post we outlined a common problem with container images - that they frequently contain artefacts that were needed to build the software or to install it into the container. We’ll show one approach that can be used to avoid this extra bloat, and so generate smaller and more secure containers.

I’ve been in meetings, often driven by the root-cause-analysis of a software fault found in the field, where the topic of code coverage has cropped up. I’m sure many of us have been in similar meetings. On occasions I’ve also been asked to justify some of my apparently poor line coverage figures, where the percentage has fallen short of what was perceived by the inquisitor as acceptable.

This is the first in a series of blog posts about building better Docker images.

Docker Inc is widely acknowledged for transitioning containers from geekdom to the real world inhabited by us developers, and did this by providing easy to use tools for building, sharing and running containers. Key to this is docker build command and the Dockerfile.
