aws EKS集群pvc存储扩容

1、helm部署的postgresql服务出现了硬盘空间不足的日志，导致服务起不来

2、本想通过kuboard控制台操作，发现控制台没有权限

3、通过kubectl命令行直接操作

handlebars 复制代码

root@devops-dev:~/openclaw-platform# kubectl patch pvc data-postgre-0 -n resources -p '{"spec":{"resources":{"requests":{"storage":"200Gi"}}}}'
persistentvolumeclaim/data-postgre-0 patched

4、回到控制台查看是否扩容成功
