Docker命令等效

命令

docker-container-run

vs

如果只运行docker命令，

docker映像构建

与

docker构建

之间有什么区别

因此，

docker build

是

docker容器build

的别名。Docker最初是关于一级命令的，后来团队意识到他们需要一种方法来对命令进行分组，这就是为什么要使它与旧客户机兼容，您有这些别名

Docker以前使用类似于

Docker run

和

Docker build

的命令来运行容器或构建图像。在以后的版本中，他们觉得应该按照@tarun lalwani的建议指定并组成一个组，这样在

docker run

或

docker container run

中就没有区别了（它们只是彼此的别名）
