git - Docker:如何从 Github 存储库上的非主分支构建镜像

Question

是否可以从 Github 存储库上的非主分支构建镜像？

例如，我有一个存储库 //github.com/myAccount/docker-myImage，其中有一个分支 development 我想用于我的图像。不幸的是，以下命令似乎只允许从 master 分支进行构建:

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

这是来自 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.

也许还有其他选择，比如 docker build -t myAccount/myImage git://github.com/myAccount/docker-myImage:development？

Answer 1

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

见 docker build command reference更多选择。
