Kubernetes liveness probes are essential for maintaining application reliability by periodically checking if a container has failed and triggering a restart if necessary, ensuring automatic recovery without third-party tools. This blog explains the importance of liveness probes for detecting container failures and how they work by sending periodic HTTP requests to check the container's health. It demonstrates how to define a liveness probe in a Kubernetes deployment using YAML and highlights the role of tools like Gremlin in verifying the functionality of these probes through chaos engineering experiments. Additionally, it discusses related Kubernetes probes, such as startup and readiness probes, which help manage container startup times and readiness to handle traffic. The blog encourages users to explore further reliability risks in their Kubernetes environments using Gremlin, offering a free 30-day trial to scan for potential issues.
