Recipes and Runtimes: Making Sense of Containers in 2026 - Soundarya Rangarajan, Canonical
If you feel overwhelmed by jargon thrown around in forums, conferences, and headlines focussed on containers and the cloud, you’re not alone. In 2026, image hardening, provenance, secure supply chains—oops, it’s happening again, isn’t it? Let’s step back.
This session takes a hands-on, bottom-up approach to understand containerization. Build along as we containerize a simple app and run it, starting with a naive approach and iteratively improving it until we have a production-grade image. At each step, new concepts are introduced only once we've understood the need for them. We'll work with Docker, understand container runtimes, even touch upon new-age tools like Rockcraft and Chisel.
To make this fun, we’ll use baking as a guiding analogy: images as recipes, dependencies as ingredients, and runtime environments as kitchens!
By the end, you’ll be able to walk confidently into real-world discussions about containers, ready to participate and learn better.
