3.2.7. kubectl delete¶

Usage:

kubectl delete ([-f FILENAME] | TYPE [(NAME | -l label | --all)]) [options]

实例:

// -f, --filename=[]
$ kubectl delete -f xxx.yml

// 重启pod(删除pod,deploy监控到,会重新启动一个新的)
$ kubectl delete po <podName>

// 使用标签删除
kubectl delete po -l labelkey1=labelvalue1

# 删除整个命名空间及下面的pod
kubectl delete ns <nsName>
# 删除当前空间的pod但保留命名空间
kubectl delete po --all
# 删除当前命令空间中的所有资源(包括RC， Pod及所创建的所有Service)
kubectl delete all --all   # 第一个all是指定删除所有资源, 第二个--all选项是指定删除下面的所有实例

备注

使用kubectl delete pod无法删除使用kubectl run创建的pod 原因是: kubectl run命令是创建一个ReplicationController，然后再由RC创建Pod, 因此只要删除RC创建的Pod,RC就会重新创建一个，因此想删除此Pod,还需要删除这个RC

备注

删除rc并不会影响通过该rc已经创建好的Pod 可以通过设置replicas的值为0，然后更新此rc

Examples:

# Delete a pod using the type and name specified in pod.json.
$ kubectl delete -f ./pod.json
# Delete a pod based on the type and name in the JSON passed into stdin.
$ cat pod.json | kubectl delete -f -

# Delete pods and services with same names "baz" and "foo"
$ kubectl delete pod,service baz foo

// -l, --selector=''
# Delete pods and services with label name=myLabel.
$ kubectl delete pods,services -l name=myLabel

// --now=false
# Delete a pod with minimal delay
$ kubectl delete pod foo --now

# Force delete a pod on a dead node
$ kubectl delete pod foo --grace-period=0 --force

# Delete all pods
$ kubectl delete pods --all
