docker如何从github上build镜像

Question

官方文档中有这么个例子：

docker build github.com/creack/docker-firefox

可以看到上面的docker-firefox是一个repository并且有一个Dockerfile文件。现在我想从github上build一个redis到本地镜像（并且只需要2.8.10这个版本）
那为什么我这个不行呢：

# docker build github.com/docker-library/redis/tree/99c172e82ed81af441e13dd48dda2729e19493bc/2.8.10
2014/11/05 16:20:32 Error trying to use git: exit status 128 (Initialized empty Git repository in /tmp/docker-build-git067001920/.git/
error: The requested URL returned error: 403 while accessing https://github.com/docker-library/redis/tree/99c172e82ed81af441e13dd48dda2729e19493bc/2.8.10/info/refs

fatal: HTTP request failed
)

这样子也不行
# docker build https://github.com/docker-library/redis/blob/99c172e82ed81af441e13dd48dda2729e19493bc/2.8.10/Dockerfile
2014/11/05 16:22:43 Invalid Dockerfile format

请问你该如何写build?

문제는 Dockerfile에 올바르게 액세스되지 않는다는 것입니다. 호스트가 정상적으로 github에 액세스할 수 있도록 하세요.
