Ensuring consistent and secure software builds is crucial in today's cloud-native environments. At Sidero Labs, we've developed a comprehensive approach to reproducible builds for Talos Linux using a variety of tools and techniques. This talk will explore our use of Docker Buildx, Kres, and other key components that contribute to our build system. We'll share insights into our methods, challenges faced, and solutions implemented, providing practical guidance for developers aiming to achieve reproducibility in their own projects.
