如何与docker共享一个networking接口而不会导致错误?

我想在同一个界面上启动2个docker容器,所以我尝试了docker文档中的以下内容:

First container: bash-4.1$ docker run -ti --name=target ubuntu /bin/bash root@45edefd42404:/# Second container: bash-4.1$ docker run -ti --rm --net=container:target ubuntu /bin/bash setup networking failed to setns current network namespace: invalid argumentFATA[0002] Error response from daemon: Cannot start container ba28e4f14f4b3c2d7b94aa4b0cca8f5b70e6b354842818fe77b31885acc77461: setup networking failed to setns current network namespace: invalid argument 

我search了与setns相关的失败,并找不到任何相关的东西。 有什么地方我可以看看debugging呢?

我的docker守护进程日志包含这与失败(完整日志https://gist.github.com/paulweb515/990a1a9edeef1e73b752 );
