背景：
早上小伙伴打来电话，问我想要将内存挂载成硬盘使用（环境all in kubernetes）,这不是内存虚拟盘吗？tmpfs......没有搞过，google一下关键词：
kubernetes tmpfs
image.pngKubernetes tmpfs
第一个链接打开是官方文档：
image.png恩也有中文版：
image.png简单的介绍都是。
yaml示例
谷歌的第二个链接打开yaml的示例一个可以参照一下：
image.png最后修改一下我的yaml and apply:
代码语言：txt复制apiVersion: apps/v1

image.png参照官方文档medium sizeLimit .500Mi是程序小伙伴让设置的
最后apply yaml文件：
代码语言：txt复制kubectl apply -f pvp-game1.yaml -n develop
image.png验证一下：
代码语言：txt复制kubectl get pods -n develop|grep pvp-game
kubectl exec -it pvp-game-1-c58694b5c-bf4nl bash -n develo
df -h
image.png不求甚解，解决.......
