监控页面出现看到有运行失败的pod

1) 查看有哪些不运行的pod
custom-metrics-apiserver日志占满空间被驱逐

[root@hadoop03 ~]# kubectl get pod -A
[root@hadoop03 ~]# kubectl get pod -n prom | grep Evicted
custom-metrics-apiserver-694844dfbc-27jcs   /     Evicted             6d7h
custom-metrics-apiserver-694844dfbc-2qqhq   /     Evicted             21h
custom-metrics-apiserver-694844dfbc-2r9xd   /     Evicted             4d9h
custom-metrics-apiserver-694844dfbc-44zlc   /     Evicted             4d23h
custom-metrics-apiserver-694844dfbc-48knc   /     Evicted             3d20h
custom-metrics-apiserver-694844dfbc-49j9n   /     Evicted             9d

custom-metrics-apiserver-694844dfbc-4kfpg   /     Evicted             4d23h

2) 获取所有Evicted pod名称

[root@hadoop03 ~]# kubectl get pod -n prom | grep Evicted | awk '{print $1}'
custom-metrics-apiserver-694844dfbc-27jcs
custom-metrics-apiserver-694844dfbc-2qqhq
custom-metrics-apiserver-694844dfbc-2r9xd
