Dockerfiles have versions?

16 minutes

I break down why Dockerfile frontends exist and how Docker's build engine "BuildKit" is giving us updated Dockerfile features.

😇 My new GitHub Security workshop has launched! A free 2-hour workshop with hands-on labs to harden your repos and your workflows from common supply chain attacks. I'll cover how attackers are getting in, and then we'll lock down a sample repo so you know what needs to be done to protect your code. You'll leave with a deep understanding of risks and mitigations as well as a list of helpful tools to keep your repos safe, including my new "gasa" tool for scanning your repos and orgs.

The TL;DR of this podcast is to add this to your Dockerfiles as the first line, always and forever.

# syntax=docker/dockerfile:1

It'll ensure your Dockerfile will have access to the latest v1.x features of the "Dockerfile frontend" feature of BuildKit.
