Almost all of Datadog now runs on Kubernetes, but for a long time we needed dedicated nodes running Docker to build container images. We have recently migrated container image builds to Kubernetes and it's been an interesting journey!

The main challenge to build container images inside Kubernetes is to achieve it without additional privileges. We will explain why we chose buildkit in rootless mode, the architecture we ended up using, as well as the challenges we faced.

Building container images in rootless mode worked flawlessly for over 90% of our images, but for the remaining 10% we encountered complex and interesting issues. We will dive into these problems and explain in detail how rootless builds work and why they sometimes behave differently. We will also explain how we addressed these issues together with the community.
