From docker build to docker buildx

Join us for a FREE lunch & learn with Jérôme Petazzoni to explore the past 9 years of container build evolution.

Course Description

This is a free, 1-hour event for engineers who want to learn how to take advantage of the new “docker build” features.

When Docker launched, the first container image builder we had was “docker build” and the now famous Dockerfile. Nine years later, Dockerfiles are still here, but they changed a lot: multi-stage builds, multi-arch images… And they leverage BuildKit, a general purpose parallel execution backend that also powers various build and CI systems like Earthly or the new and promising Dagger.

In this presentation, we’ll demo the new Docker builder in action, and highlight some scenarios where it really shines compared to the original. Big monorepos, cross-platform builds, building images on Kubernetes clusters: Jérôme will show you how to take advantage of the new features, whether you work with boring but moneymaking legacy apps, or shiny new stuff.

About the Instructor:

Jérôme was part of the team that built, scaled, and operated the dotCloud PAAS, before that company became Docker. He worked seven years at the container startup, where he wore countless hats and ran containers in production before it was cool.

He loves to share what he knows, which led him to give hundreds of talks and demos on containers, Docker, and Kubernetes.
