Are you still building images like it's 2015? This talk will get you up-to-speed with modern build technology and techniques and building images in seconds rather than minutes. This can make an enormous difference in CI/CD where a small improvement can reduce costs and speed up delivery.

We'll start by taking a look at what an OCI container image is, before delving into the different options for assembling them. After understanding why things are the way they are, we'll dive into some of the options for achieving vastly faster build times and smaller images. We'll also look at supply chain concerns such as SLSA, SBOMs and attestations.

We'll explore buildkit, buildpacks, Dagger, ko, Apko, Rockcraft and Nix amongst other technologies.

Come along and learn how to move beyond the plain Dockerfile!
