Explore the Container Runtime Interface (CRI) in Kubernetes through this 39-minute conference talk from KCD Taipei 2025. Learn how CRI, introduced in Kubernetes v1.5 in 2016, enables container runtime agnostic development and discover the technical details of how it functions within the Kubernetes ecosystem. Examine a practical implementation example through KEP 4960: Container Stop Signals, which added the StopSignal field to container lifecycle configurations, allowing users to set custom stop signals directly from deployment specifications rather than being limited to container image configurations. Gain insights into developing and testing CRI changes locally, working with different container runtimes, and building and testing Kubernetes modifications in a local environment. Understand the development workflow for contributing to kubelet and CRI areas of Kubernetes, making this session valuable for developers interested in contributing to these core Kubernetes components.
