spark on k8s: master pod kube-proxy-mkbp7 Evicte -- The node was low on resource: ephemeral-storag

spark on k8s 集群发现kube-proxy-mkbp7异常,总是Evicted状态,其他node节点上pod正常。

1. 通过 kubectl describe pod XXXXX -n  kube-system 查看pod信息,发现报错日志如下:

The node was low on resource: ephemeral-storage. Container kube-proxy was using 64Ki, which exceeds its request of 0.

2. 通过df -h 查看本地磁盘使用情况发现,根目录可用磁盘空间不足10%;

3. 清理根目录磁盘空间,重试后pod正常;
