Best Practices for Applications on Kubernetes - Frequent Updates and Stability

Explore best practices for deploying applications on Kubernetes to achieve both frequent updates and stability in this informative conference talk. Learn about container health checks, CPU and memory allocation settings, and techniques for graceful shutdown implementation. Gain insights into Kubernetes resource and container management behavior to determine optimal configurations for your applications. Discover unique practices employed by Yahoo Japan for running numerous Java application containers, including containerized Java VM tuning and automatic warm-up techniques. Delve into topics such as preventing pod shutdowns, handling high load triggers, CPU throttling, memory usage optimization, garbage collection strategies, and implementing liveness probes. Understand how to safely stop ports, manage traffic during updates, and create effective manifests for your Kubernetes deployments.
