10 Years of Kubernetes
https://kubernetes.io/blog/2024/06/06/10-years-of-kubernetes/
Ten (10) years ago, on June 6th, 2014, the first commit of Kubernetes was pushed to GitHub. That first commit with 250 files and 47,501 lines of go, bash and markdown kicked off the project we have today. Who could have predicted that 10 years later, Kubernetes would grow to become one of the largest Open Source projects to date with over 88,000 contributors from more than 8,000 companies, across 44 countries.
This milestone isn't just for Kubernetes but for the Cloud Native ecosystem that blossomed from it. There are close to 200 projects within the CNCF itself, with contributions from 240,000+ individual contributors and thousands more in the greater ecosystem. Kubernetes would not be where it is today without them, the 7M+ Developers, and the even larger user community that have all helped shape the ecosystem that it is today.
Kubernetes' beginnings - a converging of technologies
The ideas underlying Kubernetes started well before the first commit, or even the first prototype (which came about in 2013). In the early 2000s, Moore's Law was well in effect. Computing hardware was becoming more and more powerful at an incredibly fast rate. Correspondingly, applications were growing more and more complex. This combination of hardware commoditization and application complexity pointed to a need to further abstract software from hardware, and solutions started to emerge.
Like many companies at the time, Google was scaling rapidly, and its engineers were interested in the idea of creating a form of isolation in the Linux kernel. Google engineer Rohit Seth described the concept in an email in 2006:
We use the term container to indicate a structure against which we track and charge utilization of system resources like memory, tasks, etc. for a Workload.
Google's Borg system for managing application orchestration at scale had adopted Linux containers as they were developed in the mid-2000s. Since then, the company had also started working on a new version of the system called "Omega." Engineers at Google who were familiar with the Borg and Omega systems saw the popularity of containerization driven by Docker. They recognized not only the need for an open source container orchestration system but its "inevitability," as described by Brendan Burns in this blog post. That realization in the fall of 2013 inspired a small team to start working on a project that would later become Kubernetes. That team included Joe Beda, Brendan Burns, Craig McLuckie, Ville Aikas, Tim Hockin, Dawn Chen, Brian Grant, and Daniel Smith.
In March of 2013, a 5-minute lightning talk called "The future of Linux Containers," presented by Solomon Hykes at PyCon, introduced an upcoming open source tool called "Docker" for creating and using Linux Containers. Docker introduced a level of usability to Linux Containers that made them accessible to more users than ever before, and the popularity of Docker, and thus of Linux Containers, skyrocketed. With Docker making the abstraction of Linux Containers accessible to all, running applications in much more portable and repeatable ways was suddenly possible, but the question of scale remained.

A decade of Kubernetes
Kubernetes' history begins with that historic commit on June 6th, 2014, and the subsequent announcement of the project in a June 10th keynote by Google engineer Eric Brewer at DockerCon 2014 (and its corresponding Google blog).
Over the next year, a small community of contributors, largely from Google and Red Hat, worked hard on the project, culminating in a version 1.0 release on July 21st, 2015. Alongside 1.0, Google announced that Kubernetes would be donated to a newly formed branch of the Linux Foundation called the Cloud Native Computing Foundation (CNCF).
Despite reaching 1.0, the Kubernetes project was still very challenging to use and understand. Kubernetes contributor Kelsey Hightower took special note of the project's shortcomings in ease of use and on July 7, 2016, he pushed the first commit of his famed "Kubernetes the Hard Way" guide.
The project has changed enormously since its original 1.0 release; experiencing a number of big wins such as Custom Resource Definitions (CRD) going GA in 1.16 or full dual stack support launching in 1.23 and community "lessons learned" from the removal of widely used beta APIs in 1.22 or the deprecation of Dockershim.
Some notable updates, milestones and events since 1.0 include:
December 2016 - Kubernetes 1.5introduces runtime pluggability with initial CRI support and alpha Windows node support. OpenAPI also appears for the first time, paving the way for clients to be able to discover extension APIs.
This release also introduced StatefulSets and PodDisruptionBudgets in Beta.
April 2017 — Introduction of Role-Based Access Controls or RBAC.
June 2017 — In Kubernetes 1.7, ThirdPartyResources or "TPRs" are replaced with CustomResourceDefinitions (CRDs).
December 2017 — Kubernetes 1.9 sees the Workloads API becoming GA (Generally Available). The release blog states: "Deployment and ReplicaSet, two of the most commonly used objects in Kubernetes, are now stabilized after more than a year of real-world use and feedback."
December 2018 — In 1.13, the Container Storage Interface (CSI) reaches GA, kubeadm tool for bootstrapping minimum viable clusters reaches GA, and CoreDNS becomes the default DNS server.
September 2019 — Custom Resource Definitions go GAin Kubernetes 1.16.
August 2020 — Kubernetes 1.19 increases the support window for releases to 1 year.
December 2020 — Dockershim is deprecated in 1.20
April 2021 — the Kubernetes release cadence changes from 4 releases per year to 3 releases per year.
July 2021 — Widely used beta APIs are removed in Kubernetes 1.22.
May 2022 — Kubernetes 1.24 sees beta APIs become disabled by default to reduce upgrade conflicts and removal of Dockershim, leading to widespread user confusion (we've since improved our communication!)
December 2022 — In 1.26, there was a significant batch and Job API overhaul that paved the way for better support for AI /ML / batch workloads.
PS: Curious to see how far the project has come for yourself? Check out this tutorial for spinning up a Kubernetes 1.0 cluster created by community members Carlos Santana, Amim Moises Salum Knabben, and James Spurin.
Kubernetes offers more extension points than we can count. Originally designed to work with Docker and only Docker, now you can plug in any container runtime that adheres to the CRI standard. There are other similar interfaces: CSI for storage and CNI for networking. And that's far from all you can do. In the last decade, whole new patterns have emerged, such as using
Custom Resource Definitions (CRDs) to support third-party controllers - now a huge part of the Kubernetes ecosystem.
The community building the project has also expanded immensely over the last decade. Using DevStats, we can see the incredible volume of contribution over the last decade that has made Kubernetes the second-largest open source project in the world:
88,474 contributors
15,121 code committers
4,228,347 contributions
158,530 issues
311,787 pull requests
Kubernetes today
Since its early days, the project has seen enormous growth in technical capability, usage, and contribution. The project is still actively working to improve and better serve its users.
In the upcoming 1.31 release, the project will celebrate the culmination of an important long-term project: the removal of in-tree cloud provider code. In this largest migration in Kubernetes history, roughly 1.5 million lines of code have been removed, reducing the binary sizes of core components by approximately 40%. In the project's early days, it was clear that extensibility would be key to success. However, it wasn't always clear how that extensibility should be achieved. This migration removes a variety of vendor-specific capabilities from the core Kubernetes code base. Vendor-specific capabilities can now be better served by other pluggable extensibility features or patterns, such as Custom Resource Definitions (CRDs) or API standards like the Gateway API. Kubernetes also faces new challenges in serving its vast user base, and the community is adapting accordingly. One example of this is the migration of image hosting to the new, community-owned registry.k8s.io. The egress bandwidth and costs of providing pre-compiled binary images for user consumption have become immense. This new registry change enables the community to continue providing these convenient images in more cost- and performance-efficient ways. Make sure you check out the blog post and update any automation you have to use registry.k8s.io!
The future of Kubernetes
A decade in, the future of Kubernetes still looks bright. The community is prioritizing changes that both improve the user experiences, and enhance the sustainability of the project. The world of application development continues to evolve, and Kubernetes is poised to change along with it.
In 2024, the advent of AI changed a once-niche workload type into one of prominent importance. Distributed computing

Release Schedule
Next Deadline: Production Readiness Freeze, June 6th, 2024
We’re approaching the enhancements freeze deadline, with only two more weeks left. We have a total of 49 KEPs opted-in for the v1.31 release as of now. Don’t forget to talk to your SIG leads to get a lead-opted-in label if you’re planning to get your KEP shipped in v1.31. The production readiness freeze is coming up on 6th, one week before the enhancements freeze. Make sure that your KEP has a completed PRR questionnaire before the 6th to ensure enough time for the PRR team to review all the KEPs.
Featured PRs
This PR proposes making kubeadm independent of the crictl binary. This simplifies kubeadm by eliminating the need for an extra tool and offers more flexibility by allowing users to choose their preferred CRI implementation. Kubeadm will use a built-in library (cri-client) to interact with the Container Runtime Interface (CRI) instead of relying on crictl. While crictl will still be available for one more kubeadm release (v1.31), it won’t be installed by default anymore. Users who need crictl after v1.31 will have to update their scripts to install it manually. This improvement streamlines kubeadm and offers more control over CRI interactions.
KEP of the Week
KEP 4580: Deprecate and remove Kubelet RunOnce mode
This KEP proposes to deprecate and remove kubelet’s RunOnce mode. RunOnce mode does not support any of the newer Pod features like init containers and the Pod lifecycle for RunOnce mode is not well defined. Podman addresses the same use case in a more well-supported way. RunOnce mode also doesn’t work when the kubelet is running in systemd mode.
This was first brought up way back in 2017, and is finally on track to being deprecated in v1.31.
Other Merges
Restore scheduler performance on big clusters to pre-1.30 speeds, by changing NodeToStatusMap; this will break existing PostFilter plugins
You can make a kube-proxy image on Windows
LoadBalancer will check new fields for status changes
