在我的例子中，我使用下面这些

kubectl get all --all-namespaces 
kubectl delete deployment statefulset-deploymentnament(choose your deployment name)
kubectl delete sts -n default(choose your namespace) --all 
kubectl get pods --all-namespaces

问题得到了解决

对于有状态集(或服务，作业等)的部署，您可以使用此命令:

此命令终止在指定<命名空间>中运行的任何内容

kubectl -n <NAMESPACE> delete replicasets,deployments,jobs,service,pods,statefulsets --all

和有力的

kubectl -n <NAMESPACE> delete replicasets,deployments,jobs,service,pods,statefulsets --all --cascade=true --grace-period=0 --force

您可以根据年龄或时间执行kubectl get replicasets检查旧部署

如果要删除相同的应用程序当前运行pod，请根据时间删除旧部署

kubectl delete replicasets <Name of replicaset>

在学习了一个交互式教程后，我最终得到了一堆pod、服务和部署:

me@pooh ~ > kubectl get pods,services
NAME                                       READY   STATUS    RESTARTS   AGE
pod/kubernetes-bootcamp-5c69669756-lzft5   1/1     Running   0          43s

pod/kubernetes-bootcamp-5c69669756-v8vd4   1/1     Running   0          43s

me@pooh ~ > kubectl get deployments --all-namespaces
NAMESPACE     NAME                  DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE

docker        compose               1         1         1            1           1d
docker        compose-api           1         1         1            1           1d

要清理所有内容，删除—一切正常:

me@pooh ~ > kubectl delete pods,services,deployments --all
pod "kubernetes-bootcamp-5c69669756-lzft5" deleted
pod "kubernetes-bootcamp-5c69669756-n947m" deleted
pod "kubernetes-bootcamp-5c69669756-s2jhl" deleted
pod "kubernetes-bootcamp-5c69669756-v8vd4" deleted
service "kubernetes" deleted
deployment.extensions "kubernetes-bootcamp" deleted

这给我留下了一个空的Kubernetes集群:

me@pooh ~ > kubectl get pods,services,deployments
NAME                 TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
service/kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   8m

这里的许多答案都告诉我们删除一个特定的k8s对象，但你可以一次删除多个对象，而不是一个一个地删除:

Kubectl删除部署、作业、服务、pods——所有-n <命名空间>

在我的例子中，我使用OLM -操作员生命周期管理器运行OpenShift集群。OLM是控制部署的人，所以当我删除部署时，它不足以阻止pods重新启动。

只有当我删除OLM及其订阅时，部署、服务和pod才消失了。

首先列出命名空间中的所有k8s对象:

$ kubectl get all -n openshift-submariner

NAME                                       READY   STATUS    RESTARTS   AGE
pod/submariner-operator-847f545595-jwv27   1/1     Running   0          8d  
NAME                                  TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
service/submariner-operator-metrics   ClusterIP   101.34.190.249   <none>        8383/TCP   8d
NAME                                  READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/submariner-operator   1/1     1            1           8d
NAME                                             DESIRED   CURRENT   READY   AGE
replicaset.apps/submariner-operator-847f545595   1         1         1       8d

OLM没有与get all一起列出，所以我专门搜索了它:

$ kubectl get olm -n openshift-submariner

NAME                                                      AGE
operatorgroup.operators.coreos.com/openshift-submariner   8d
NAME                                                             DISPLAY      VERSION
clusterserviceversion.operators.coreos.com/submariner-operator   Submariner   0.0.1 

现在删除所有对象，包括olm、订阅、部署、副本集等:

$ kubectl delete olm,svc,rs,rc,subs,deploy,jobs,pods --all -n openshift-submariner

operatorgroup.operators.coreos.com "openshift-submariner" deleted
clusterserviceversion.operators.coreos.com "submariner-operator" deleted
deployment.extensions "submariner-operator" deleted
subscription.operators.coreos.com "submariner" deleted
service "submariner-operator-metrics" deleted
replicaset.extensions "submariner-operator-847f545595" deleted
pod "submariner-operator-847f545595-jwv27" deleted

再次列出对象-全部消失:

$ kubectl get all -n openshift-submariner
No resources found.

$ kubectl get olm -n openshift-submariner
No resources found.

这将提供关于所有pod、部署、服务和作业的信息 在命名空间中。

kubectl get pods,services,deployments,jobs

pod既可以由部署创建，也可以由作业创建

kubectl delete job [job_name]
kubectl delete deployment [deployment_name]

如果您删除了部署或作业，那么可以停止重新启动pods。
