是否可以从Github存储库上的非主分支构建映像？

例如,我有一个存储库//github.com/myAccount/docker-myImage,它有一个分支开发,我想用于我的图像.不幸的是,以下命令似乎只允许从主分支构建：

docker build -t myAccount/myImage git://github.com/myAccount/docker-myImage

以下是man docker build的相关文档：

Building an image using a URL
       This will clone the specified Github repository from the URL and use it as context.
       The Dockerfile at the root of the repository is used as Dockerfile. This only works
       if the Github repository is a dedicated repository.

              docker build github.com/scollier/Fedora-Dockerfiles/tree/master/apache

              Note: You can set an arbitrary Git repository via the git:// schema.

也许有一个替代方案,比如docker build -t myAccount / myImage git：//github.com/myAccount/docker-myImage：development？
