# Kubernetes Operations ## Purpose Operating Kubernetes clusters in production requires mastery of resource management, scheduling patterns, networking architecture, storage strategies, security hardening, and autoscaling. This skill provides operations-first frameworks for right-sizing workloads, implementing high-availability patterns, securing clusters with RBAC and Pod Security Standards, and systematically troubleshooting common failures. Use this skill when deploying applications to Kubernetes, configuring cluster resources, implementing NetworkPolicies for zero-trust security, setting up autoscaling (HPA, VPA, KEDA), managing persistent storage, or diagnosing operational issues like CrashLoopBackOff or resource exhaustion. ## When to Use This Skill **Common Triggers:** - "Deploy my application to Kubernetes" - "Configure resource requests and limits" - "Set up autoscaling for my pods" - "Implement NetworkPolicies for security" - "My pod is stuck in Pending/CrashLoopBackOff" - "Configure RBAC with least privilege" - "Set up persistent storage for my database" - "Spread pods across availability zones" **Operations Covered:** - Resource management (CPU/memory, QoS classes, quotas) - Advanced scheduling (affinity, taints, topology spread) - Networking (NetworkPolicies, Ingress, Gateway API) - Storage operations (StorageClasses, PVCs, CSI) - Security hardening (RBAC, Pod Security Standards, policies) - Autoscaling (HPA, VPA, KEDA, cluster autoscaler) - Troubleshooting
