OpenShift Commons Briefing #102: Introducing Buildah with Nalin Dahyabhai and Dan Walsh
Channel: OpenShift
Date: 19/10/2017

Buildah facilitates building OCI container images and is able to create and run containers without the Docker daemon even being installed. Buildah also allows you to easily create smaller, stronger, purpose-built containers that precisely fit your needs. A common problem people have with building container images with tools like Dockerfile and the run-time-based docker build command is the size of the image, as well as the number of build tools that end up inside of it. Another concern about these unnecessary tools is they can weaken your container by opening potential venues for hackers to take advantage. A really nice feature about Buildah is you can strengthen your container making it “stronger and more fit”. By finely tuning the creation of the container, and then adding or removing pieces as you desire, you can control the size of your container and lessen its vulnerabilities. It’s all under your control. In this briefing, Nalin and Dan will give us an overview of Buildah and a demo how to use it.
