    • Services

      ClusterIP, NodePort, and LoadBalancer.

  2. Config

    Separate config and secrets from your container images.

    • ConfigMaps

      Inject non-sensitive config into pods.

    • Secrets

      Base64-encoded secrets and how to handle them safely.

    • Namespaces

      Logical isolation within a cluster.

  3. Networking

    Route external traffic into your cluster.

    • Ingress

      HTTP/HTTPS routing, TLS termination, and path rules.
