K8S删除pod的4种方法小结

#Kubernetes向进程发送一个SIGTERM信号并等待一定的秒数（默认为30），使其正常关闭。如果它没有及时关闭，则通过SIGKILL终止该进程。因此，为了确保你的进程总是正常关闭，进程需要正确处理SIGTERM信号。
kubectl delete pod pod_name

kubectl delete pod -l nio4444=true

#删除整个命名空间（pod将会伴随命名空间自动删除）
kubectl delete   -ns  namespace_name

# 删除命名空间中的所有pod，但保留命名空间
kubectl delete pod --all

kubectl delete pods pod_name --grace-period=0 --force

kubectl delete pods pod_name --grace-period=0

root@kmaster-rj:~# kubectl delete pod pod-delete-demo --force --grace-period=0 --namespace=default
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "pod-delete-demo" force delete

kubectl patch pod pod-delete-demo -p '{"metadata":{"finalizers":null}}'

root@kmaster-rj:~# kubectl get pods -o wide
