Kubernetes is the second-largest open-source project in the world. What does it do—and why is it so widely adopted?Kat Cosgrove has led several Kubernetes releases and joined The Pragmatic Engineer podcast to share the history of Kubernetes, how it's built, when it is a good (or not so good) use case, and how you can contribute to it (and why it's a good thing to do for professional and career growth).Brought to you by•⁠ @WorkOS — The modern identity platform for B2B SaaS https://workos.com•⁠ @modal_labs — The cloud platform for building AI applications https://modal.com/pragmatic•⁠ @GetCortexApp — Your Portal to Engineering Excellence http://cortex.io/pragmaticWatch or listen:• YouTube: https://youtu.be/vBjonut1JMk• Spotify: https://open.spotify.com/episode/2zbYpj9hYwJtzGoYJGvdXN• Apple: https://podcasts.apple.com/us/podcast/how-kubernetes-is-built-with-kat-cosgrove/id1769051199?i=1000708482879• Summary and transcript: https://newsletter.pragmaticengineer.com/p/how-kubernetes-is-built-with-katThree of my takeaways from this great conversation:𝟭.

Google originally built an in-house tool to manage the tens of thousands (then hundreds of thousands and later millions) of machines: this internal tool is called Borg. The roots of Kubernetes come from Borg: but Google has since donated the project to the Cloud Native Computing Foundation (CNCF) – and today, Kubernetes is the second largest open source project, after Linux. We previously did a deepdive on How Linux is built, and touched on Google’s SRE roots in What is Reliability Engineering?𝟮. 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝗶𝘀 𝗮 𝘃𝗲𝗿𝘆 𝘄𝗲𝗹𝗹-𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝗱 𝗮𝗻𝗱 𝗼𝗿𝗴𝗮𝗻𝗶𝘇𝗲𝗱 𝗼𝗽𝗲𝗻 𝘀𝗼𝘂𝗿𝗰𝗲 𝗽𝗿𝗼𝗷𝗲𝗰𝘁. The structure of the project and all processes are well documented. The project has around 150-200 maintainers, has a few dozen SIGs (Special Interest Groups) and releases run on a 14-16 week cycle.𝟯.

More than of the members on the Release Team are “shadows” who get to learn on the job how a release is done – and, hopefully, in a release or two, become leads themselves!
