Use Kubernetes ConfigMaps as mounted files for runtime config updates, with caveats for propagation, subPath, and app reload behavior.
Debug failed Kubernetes deployments by checking events, YAML structure, image pulls, probes, resources, and scheduling rules.
Secure Kubernetes Secrets with RBAC, etcd encryption, safer mounts, external secret stores, CSI Driver, and rotation.
Navigate the critical choice of exposing Kubernetes Services externally by comparing NodePort, LoadBalancer, and Ingress. This guide details the architecture, operational layer (L4 vs. L7), use cases, and key differences in cost and complexity for each method. Learn when to use the simple NodePort for testing, the dedicated LoadBalancer for single services, or the powerful Ingress for centralized, cost-effective Layer 7 routing and complex multi-service environments.
Configure Kubernetes rolling updates with readiness probes, maxSurge, maxUnavailable, and graceful shutdown.
