Deep Dive - Unified Runtime Service Infrastructure for Containers and VMs
Explore a deep dive into unified runtime service infrastructure for containers and virtual machines in this 19-minute conference talk from CNCF. Learn about the challenges of extending Kubernetes to support both container and VM types, and discover a new runtime infrastructure designed to address these issues. Gain insights into modifications in Kubelet for managing multiple runtime services, workload-runtime late binding, partial runtime readiness handling, and unified runtime interfaces supporting both container and VM workloads. Understand operations such as reboot, snapshot, and migration. Examine the motivation behind this approach, review the high-level concepts, and explore supporting VM types and pod state management. Conclude with valuable lessons learned and future developments in this field.
