如何在i686机器上安装docker - github

How to build docker on i686 ubuntu 14.04 LTS? #10165

原答案：

Docker doesn’t support i686 right now. This needs quite a bit of work before it can happen.

Please use amd64 (x86_64) in the meantime. Please keep in mind that x86 images can be used on amd64.

docker 目前不支持 i686 的架构。
