Explore container checkpoint security in this Linux Plumbers Conference talk. Learn about a built-in mechanism for protecting sensitive data through asymmetric encryption of CRIU images. Discover how this approach enables seamless end-to-end security across cluster nodes without modifying the underlying container infrastructure. Gain insights into the project's current state, integration challenges with existing container environments, and its potential use with role-based access control in multi-tenant clusters. Understand the importance of maintaining confidentiality and integrity of application data in light of recent container checkpointing integration in Kubernetes.
