Người mới nên học docker-compose hay Kubernetes trước?

Học docker-compose trước. Nó dạy bạn tư duy multi-service (network, volume, env, depends_on) mà không bị ngợp bởi control plane của K8s. Khi hiểu compose rồi, ánh xạ sang K8s (Deployment/Service/ConfigMap) sẽ rất tự nhiên. Nhảy thẳng K8s dễ nản vì phải học cả chục khái niệm cùng lúc.
