The Hummingbird Project is a set of rapidly rebuilt container images, as small, and with as few CVEs as possible, tracking upstream as closely as possible, enabling users to meet audits and certifications easily.
You might wonder what it has in common with Fedora, how it shares content with Fedora and how it's a contributing part of Fedora. We’ll cover all those topics, and look at the high degree of automation involved, where we use AI, and the build pipelines that we use to achieve this.
But why would we do such a thing? Why would someone want such rapidly updated, minimal containers .We’ll examine that too, and how many users have different expectations of the containers nowadays.
