Dockerfiles have versions?

Download MP3
I break down why Dockerfile frontends exist and how Docker's build engine "BuildKit" is giving us updated Dockerfile features.

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.
