Kubernetes End of Life Dates

Developers rely on container orchestration systems to streamline software deployment, scaling, and management, and one popular solution is Kubernetes, also known as K8s. Originally designed by Google, this open-source project has evolved over time, with a worldwide community of contributors now maintaining it. The project's maintainers continually update and refine Kubernetes to ensure it remains a robust and reliable tool for automating software deployment and scaling. Kubernetes has become a cornerstone of DevOps practices, allowing developers to focus on writing code rather than managing infrastructure.

The Kubernetes ecosystem is vast, with a total of 21 versions released to date, of which 17 have reached their end-of-life. Currently, four versions remain active, with the latest stable version being 1.36.1. As the project continues to evolve, older versions are phased out, with the next end-of-life date scheduled for June 28, 2026, when version 1.33 will expire. This follows the recent end-of-life of version 1.32 on February 28, 2026. Understanding the lifecycle of Kubernetes versions is essential for developers to ensure they are running a supported and secure version of the software.

With no known vulnerabilities tracked, Kubernetes presents a strong security posture, boasting zero total CVEs and zero critical CVEs. As a result, there is no most affected version, and no specific action is required to address known security vulnerabilities. However, it is still crucial for developers to stay up-to-date with the latest versions and security advisories to ensure the long-term security and stability of their deployments. By doing so, they can leverage the full potential of Kubernetes while minimizing potential risks, and the community's ongoing maintenance efforts will continue to provide a secure and reliable platform for container orchestration.
