Kubernetes

To fix Kubernetes OOMKilled or CPU throttling, configure proper resource requests and limits for containers. This prevents resource starvation and ensures stable pod lifecycle management by allocating guaranteed CPU and memory.

Troubleshoot Kubernetes traffic routing failures by verifying service selector matches and probe status. Use kubectl commands to inspect pod events and restore connectivity by ensuring labels align and readiness probes pass successfully.

Configuring Kubernetes liveness and readiness probes requires setting distinct thresholds for health monitoring. Implement startup probes alongside readiness and liveness checks to ensure high availability and prevent premature container restarts.

Kubernetes deployment failures with RBAC or networking errors stem from common configuration pitfalls. Identify these issues by inspecting cluster events and access controls to ensure service discovery and permissions are configured correctly.

Yes, you can use kubectl to diagnose Kubernetes deployment specification issues. Execute standard commands to access container logs, inspect cluster events, and gain shell access for comprehensive troubleshooting of failing pods.

You need startup probes in Kubernetes pod lifecycle management when applications require significant initialization time. They prevent premature liveness probe failures during slow boots, ensuring production-grade reliability before traffic routing begins.
