我已经部署了我的第一个带有1 Pod的Google Cloud容器群集。 对于像我这样的人来说，这个过程非常容易。
我很惊讶地看到我的pod中已经有这么多容器在运行。他们都需要吗？我可以杀死他们以释放资源吗？
我的图片已经有php-fpm和nginx。
有人知道这些已经在pod中运行的docker容器以及它们是否可以被杀死？

答案 0 :(得分：2)
以下是其中一些内容：
总而言之，这些是Kubernetes的正常部分，不应该被关闭。他们通常只使用很少的资源，所以不会造成任何伤害。 Kubernetes使用＆＃39;命名空间＆＃39;并将它们保存在kube-system命名空间中。如果你使用kubernetes而不是kubectl get pods而不是docker ps，那么它们通常不会出现。
