"Please welcome Flatcar releases of this month..." - that's how every Flatcar releases are announced but what is behind? What are the various tasks involved to reach this release status? In this talk, Sayan and Mathieu, two Flatcar engineers involved in the release automation process, will guide you into this (open-)journey. Open? Yes, almost all the release cycle is public, anyone interested into building and releasing complex systems such as Linux based Operating System are invited to join. Flatcar is a Linux based OS designed to run container workloads: no package manager, /usr is read-only - it is the responsibility of the maintainers to keep the system up-to-date. From the definition of the content, to the payload release, passing by the "go/no-go" meeting let's see how Flatcar is defined, built and released and how the community is involved at each steps.
