记一次批量删除Evicted状态的pod

记一次批量删除Evicted状态的pod

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 istio-pilot-5c4995d687-c4zw8 0/1 Evicted 0 21m istio-pilot-5c4995d687-cv79t 0/1 Evicted 0 21m istio-pilot-5c4995d687-lwkf8 0/1 Evicted 0 21m istio-pilot-5c4995d687-q4f5j 0/1 Evicted 0 21m istio-pilot-5c4995d687-q77r2 0/1 Evicted 0 21m istio-sidecar-injector-746f7c7bbb-9gv95 0/1 Evicted 0 51m 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 pod "grafana-6b65874977-2w54r" deleted pod "grafana-6b65874977-pcctb" deleted pod "grafana-6b65874977-s6mkb" deleted pod "istio-galley-5fc6d6c45b-tlbzs" deleted pod "istio-ingressgateway-6d759478d8-c8psq" deleted pod "istio-pilot-5c4995d687-5jtwd" deleted pod "istio-pilot-5c4995d687-678hg" deleted pod "istio-pilot-5c4995d687-bxt8p" deleted pod "istio-pilot-5c4995d687-c4zw8" deleted pod "istio-pilot-5c4995d687-cv79t" deleted pod "istio-pilot-5c4995d687-lwkf8" deleted pod "istio-pilot-5c4995d687-q4f5j" deleted pod "istio-pilot-5c4995d687-q77r2" deleted pod "istio-sidecar-injector-746f7c7bbb-9gv95" deleted pod "kiali-8559969566-pfh6t" deleted pod "prometheus-66c5887c86-smcgv" deleted
