Explore the intricacies of isolation and security in Kubernetes ecosystems through this informative conference talk. Delve into the complexities of verifying and comprehending isolation guarantees across various layers, from cluster to container levels. Learn to assess the necessary isolation requirements at each tier and understand the impact and trade-offs of optimizing isolation at specific layers. Gain insights into isolation strategies at the cluster, namespace, pod, and container levels. Examine a real-world case study on running Jupyter Notebooks within Kubernetes, focusing on achieving pod-level isolation to create separate user spaces for individual notebooks in a cluster. This presentation offers valuable knowledge for developers and end-users working with Kubernetes and other CNCF-hosted projects, enhancing their understanding of security and isolation in cloud-native environments.
