用一行命令搞定：
kubectl get pods --all-namespaces -o wide | grep Evicted | awk '{print $1,$2}' | xargs -L1 kubectl delete pod -n
如：
kubectl get pods --all-namespaces -o wide | grep Evicted | awk '{print $1,$2}' | xargs -L1 kubectl delete pod -n

也可以把Evicted换成OutOfcpu等其它状态使用。
批量加标签：
for node in `kubectl get node | grep node | awk '{print $1}'`; do kubectl label node $node edug=traefik ; done
停用deployment:
kubectl patch deployment -p '{"spec":{"replicas":0}}' -n public-devops-tomcat-dev public-devops-oomtest-tomcat-dev
启用deployment:
kubectl patch deployment -p '{"spec":{"replicas":1}}' -n public-devops-tomcat-dev public-devops-oomtest-tomcat-dev
批量停用deployment:
kubectl get deployment --all-namespaces -o wide | grep public-devops-tomcat-dev | awk '{print $1,$2}' | xargs -L1 kubectl patch deployment -p '{"spec":{"replicas":0}}' -n
