kubectl顶部容器--all-namespaces |排序-反向-键4-数字| head -10给出群集中的顶部容器。如何获得每个节点上消耗内存最多的容器？

Answer 1

如果仍然需要排序并保留每个节点Pod列表的前十个元素，则可以使用以下命令： <!DOCTYPE html> <html lang="en"> <head> <script language="javascript" type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="hash.js"></script> <meta charset="UTF-8"> <title>Insert title here</title> </head> <body > <form name="fileForm"> <button onclick="b()">button</button> <input type="file" name="file1" id="inputFile" accept="video/*" /> <div id="tt"> </div> </form> </body> </html>

kubectl描述节点node_name将为您提供如下内容。

Answer 3

尝试：

kubectl get pods --all-namespaces -o wide | grep <node> | grep Running | awk '{print $1" "$2}' | while read namespace pod; do kubectl top pods --no-headers --namespace $namespace $pod; done  | sort -t ' ' --key 2 --numeric --reverse

这会检查所有命名空间，以防您拥有

这在macOS上对我有效，其中xargs不接受相同的参数，但应在任何* nix系统中工作

kubectl命令，用于查找每个节点上消耗内存最多的Pod
