由于node节点资源不足，造成资源的争抢，并出现大量的驱逐的pod，可以使用grep Evicted查看哪些pod[root@k8s-master istio-1.4.2]# kubectl get pods -n istio-system | grep Evicted
grafana-6b65874977-2w54r 0/1 Evicted 0 21m
grafana-6b65874977-pcctb 0/1 Evicted 0 21m
grafana-6b65874977-s6mkb 0/1 Evicted 0 29m
istio-galley-5fc6d6c45b-tlbzs 0/1 Evicted 0 25m
istio-ingressgateway-6d759478d8-c8psq 0/1 Evicted 0 28m
istio-pilot-5c4995d687-5jtwd 0/1 Evicted 0 21m
istio-pilot-5c4995d687-678hg 0/1 Evicted 0 48m
istio-pilot-5c4995d687-bxt8p 0/1 Evicted 0 21m

kiali-8559969566-pfh6t 0/1 Evicted 0 51m
prometheus-66c5887c86-smcgv 0/1 Evicted 0 51m针对这么istio-system命名空间下的pod，再找出Evicted的pod，执行delete
[root@k8s-master istio-1.4.2]# kubectl get pods -n istio-system | grep Evicted |awk ‘{print $1}‘ |xargs kubectl -n istio-system delete pod
