Explore container lifecycle management in Kubernetes with this comprehensive conference talk. Delve into PID 1, signal handling, hooks, and probes to ensure proper application lifecycle management. Learn strategies for reliable container execution, including init systems like dumb-init and tini, postStart and preStop lifecycle hooks, and Liveness, Readiness, and Startup probes. Understand key differences between postStart hooks, initContainers, and Startup Probes. Discover techniques for handling orphan and zombie processes, graceful termination, and self-healing containers. Gain insights into Pod lifecycle phases, container states, and the intricacies of probes through code walkthroughs. Examine the usage of Init Containers and their impact on scheduling and resources in Kubernetes environments.
