我创建了一个python代码删除所有在命名空间

delall.py

import json,sys,os;

obj=json.load(sys.stdin);
for item in obj["items"]:
        os.system("kubectl delete " + item["kind"] + "/" +item["metadata"]["name"] + " -n yournamespace")

然后

kubectl get all -n kong -o json | python delall.py

Kubectl bulk (bulk-action on krew)插件可能对您有用，它为您提供了选定资源的批量操作。删除pod的命令

 ' kubectl bulk pods -n namespace delete '

你可以在这里查看细节

仅删除所有命名空间中的所有pod(重新启动部署)

 kubectl get pod -A -o yaml | kubectl delete -f -

kubectl delete daemonsets,replicasets,services,deployments,pods,rc,ingress --all --all-namespaces

也摆脱了烦人的复制控制器。

你只需要sed这样做:

kubectl get pods --no-headers=true --all-namespaces |sed -r 's/(\S+)\s+(\S+).*/kubectl --namespace \1 delete pod \2/e'

解释道:

use command kubectl get pods --all-namespaces to get the list of all pods in all namespaces. use --no-headers=true option to hide the headers. use s command of sed to fetch the first two words, which represent namespace and pod's name respectively, then assemble the delete command using them. the final delete command is just like: kubectl --namespace kube-system delete pod heapster-eq3yw. use the e modifier of s command to execute the command assembled above, which will do the actual delete works.

为了避免在kube-system namespace中删除pods，只需要在sed命令前添加grep -v kube-system排除kube-system namespace即可。

如果你有hpa，那么缩小。
