pod内容器共享网络命名空间，可以通过127.0.0.1:port互联
kubectl logs
一个POD中通常只放一个主容器，其他容器作为辅助sidecar，例如日志收集、代理、istio等
而类似lnmt部署分多个pod使用
kubectl expose 创建Service对象以将应用程序"暴露"于网络中
kubectl expose deployment damon
kubectl cluster-info
kubectl scale deployment nginx --replicas 5
# Pod容器的字段拼写忘记了
kubectl explain pods.spec.containers
