Pod接口ExtendPathMode: PodUID如何与社区client-go兼容?
使用场景
社区Pod结构体中没有ExtendPathMode,用户使用client-go调用创建pod或deployment的API接口时,创建的pod中没有ExtendPathMode。为了与社区的client-go兼容,CCE提供了如下解决方案。
解决方案
- 创建pod时,在pod的annotation中需增加kubernetes.io/extend-path-mode。
- 创建deployment时,需要在template中的annotation增加kubernetes.io/extend-path-mode。
如下为创建pod的yaml示例,在annotation中添加kubernetes.io/extend-path-mode关键字后,完全匹配到containername,name,mountpath三个字段,则会在volumeMount中增加对应的extendpathmode:
