环境：

centos6.5
2.6.32-431.29.2.el6.x86_64
docker version
**Client version: 1.1.2
Client API version: 1.13
Go version (client): go1.2.2
Git commit (client): d84a070/1.1.2
Server version: 1.1.2
Server API version: 1.13
Go version (server): go1.2.2
Git commit (server): d84a070/1.1.2**

在使用docker build --rm -t aaa .后报错

接着运行docker run --rm -ti centos:centos6 /bin/sh也报错

如果在build前执行run可以正常使用。
