Introduction to Kubernetes for Developers
summary
Kubernetes basics with concrete commands and tools: use k3d/k3s to create a local cluster, manage resources with kubectl and inspect with k9s, create a Deployment (example: 12 replicas handled by a ReplicaSet) and expose it via Service types (ClusterIP, NodePort, LoadBalancer) or an Ingress controller (nginx/Traefik), and note secrets are just base64 so use Vault or cloud KMS for real secrets. Also covers ConfigMaps, labels/selectors, external-dns, MetalLB, and observability stacks (ELK or Promtail/Loki/Grafana).
