现在你有组像经理多个命令container，image。当你运行这个组

$ docker image 

Usage: docker image COMMAND 

Manage images 

Options: 
     --help Print usage 

Commands: 
    build  Build an image from a Dockerfile

    push  Push an image or a repository to a registry 
    rm   Remove one or more images 
    save  Save one or more images to a tar archive (streamed to STDOUT by default) 
    tag   Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE 

因此，作为docker build是一个别名docker container build。 Docker最初都是关于一级命令的，后来团队意识到他们需要一种将命令分组的方法，这就是为什么要保持它与旧的客户端兼容的原因

Answer 2

Docker以前使用的命令如docker run和docker build运行容器或构建映像。在后来的版本中，他们觉得他们应该按照@ tarun-lalwani的建议指定并创建一个组，因此docker run或docker container run（它们只是彼此的别名）没有区别。
