[英]Append Namespace and pod name in output of resource utilization
我已经能够通过以下方式使用 kubectl 插件生成以下 output ：
./kubectl get namespaces | awk '{ print $1 }' | while read x; do ./kubectl resource-capacity --sort cpu.util --namespace $x --util --pod-count --pods; done
Error getting Pod Metrics: pods.metrics.k8s.io is forbidden: User "u-567" cannot list resource "pods" in API group "metrics.k8s.io" in the namespace "NAME"
For this to work, metrics-server needs to be running in your cluster

我想在每个循环中将 append 命名空间作为列，我该怎么做。
提前致谢
答案根据OP的评论进行了调整。
按节点打印 pod 资源的命令：
kubectl describe node | perl -0777 -wnE '@pods = /Name:\s+([^ ]+)\n.*?Non-terminated\s+Pods:\s+\([0-9]+\s+in\s+total\)\n(.*?)\nAllocated resources:/gs;say for @pods'
第一步，将每个节点的output写入各自的文件。
kubectl describe node | perl -0777 -wnE '@pods = /Name:\s+([^ ]+)\n.*?Non-terminated\s+Pods:\s+\([0-9]+\s+in\s+total\)\n(.*?)\nAllocated resources:/gs;say for @pods'|awk -v OFS=',' '/^[^ ]+/{node=$0;next} {print $0 > node ".csv"}'
上面的命令将创建如下文件：
ls -lrt *.csv
-rw-rw-r-- 1 p.. p.. 2800 Sep 8 12:43 dev-kube-worker-3.csv
-rw-rw-r-- 1 p.. p.. 2782 Sep 8 12:43 dev-kube-worker-2.csv
-rw-rw-r-- 1 p.. p.. 2800 Sep 8 12:43 dev-kube-worker-1.csv
-rw-rw-r-- 1 p.. p.. 1551 Sep 8 12:43 dev-kube-controller-1.csv
最后修改：但是这些文件的内容不会是CSV格式，所以要使内容为CSV：
kubectl describe node | perl -0777 -wnE '@pods = /Name:\s+([^ ]+)\n.*?Non-terminated\s+Pods:\s+\([0-9]+\s+in\s+total\)\n(.*?)\nAllocated resources:/gs;say for @pods'|awk -v OFS=',' '/^[^ ]+/{node=$0;next} {$1=$1;print $0 > node ".csv"}'
