In this post we look at using buildah to generate container images that only contain what we want, no extra fluff. We show how this can let us generate truly small images that will load faster and be more secure, and do this without the need for the Docker daemon to be running.
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.
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.
