There is no such thing as “Vanilla Kubernetes”
- 1. There is no such thing as “Vanilla Kubernetes” Bob Dubois Cloud Specialist, Red Hat
- 2. 6 years @ Red Hat Tech background in network security, storage and data management Long-term OSS user (RHEL 4 certified, and RHEL 7, and OpenStack, and OpenShift, and ...) Spokesman & public speaker for Red Hat /usr/bin/whoami

- 4. ONE ASSUMPTION 4 Everyone understands running unsupported FOSS Kubernetes is a bad idea
- 5. KUBERNETES IS NOT THE END GAME 5 It’s a building block to build app platforms * https://twitter.com/kelseyhightower/status/935252923721793536
- 6. BUILDING AN APP PLATFORM IS EXPENSIVE 6 Are you a app platform vendor or do you want to focus on your mission? * www.crunchbase.com $33.5M $30M $257.3M$272.9M It takes real money to build an app platform. Here’s what it took for these start-ups.
- 7. BUILDERS OF APP PLATFORMS ARE EXPENSIVE 7 The same goes for Kubernetes contributors * https://neuvoo.com/salary/?job=Kubernetes+Docker+Engineer https://neuvoo.com/salary/?job=software+developer https://www.generalschedule.org/GS-15 The average salary for a standard software developer is $101,490. A GS-15 is at $106,595!
- 8. KUBERNETES BUILDERS’ VALUE IS EVEN MORE 8 The market value of Kubernetes for resale talent is incredible * Citation needed We each paid plenty per engineer for a Kubernetes talent infusion. $7M$1.9M
- 9. You realize Kubernetes is hard.
- 10. ORGANIZATIONS NEED LOTS OF HELP 10 Going beyond community support is critical * https://insights.stackoverflow.com/trends?tags=kubernetes One half of a percent of Stack Overflow questions are Kubernetes related. Red Hat answers nearly 2,000 support tickets for Kubernetes a month!
- 11. You’re not in the business of building app platforms.
- 12. A LOT OF THIS GOING AROUND 12 The late-entry Kubernetes vendors want you to believe in “Vanilla”
- 13. THE VANILLA KUBERNETES MYTHS 13 Why IT shops swoon over “Vanilla” Kubernetes and its perceived value No “vendor lock-in” Ultimate portability across Kubernetes Clusters Always on latest version
- 14. THE VANILLA KUBERNETES REALITY 14 “Vanilla” Kubernetes is not really vanilla at all Every vendor operates Kubernetes differently; this matters Every vendor configures their Kubernetes distribution differently No vendor is in lockstep with the latest upstream * https://medium.com/@jzelinskie/youre-not-running-vanilla-kubernetes-2f2359666bf9
- 15. VANILLA KUBERNETES IS NOT A THING 15 In practice, no vendor distribution of Kubernetes is “Vanilla”
- 16. So what are late-entry Kubernetes vendors talking about?
- 17. “PURE” KUBERNETES PRIMITIVES 17 Late-entry vendors are talking about the developer experience kubectl kube-apiserver
- 18. KUBERNETES CONFORMANCE 18 Interoperability at the API “The new Certified Kubernetes Conformance Program gives enterprise organizations the confidence that workloads that run on any Certified Kubernetes Distribution or Platform will work correctly on any other version,” said Dan Kohn, Executive Director, Cloud Native Computing Foundation. “The interoperability that this program ensures is essential to Kubernetes meeting its promise of offering a single open source software project supported by many vendors that can deploy on any public, private or hybrid cloud.” One of the goals of the project has always been consistency and portability. Kubernetes sits on top of the infrastructure and enables you to describe your workload in a common format. Kubernetes makes it easy to move workloads from one place to another, or combine disjointed environments with a shared control plane. This program gives end users the confidence that when they use a Certified Kubernetes product they can rely on a high level of common functionality. It gives Independent Software Vendors (ISVs) confidence that if their customer is using a Certified Kubernetes platform that their software will behave as expected. * https://github.com/cncf/k8s-conformance
