Docker命令等效
什么是命令docker container run与docker run命令之间的差异docker image build与docker build之间的区别
如果你只是运行docker命令
$ docker Usage: docker COMMAND A self-sufficient runtime for containers Options: --config string Location of client config files (default "/Users/tarun.lalwani/.docker") -D, --debug Enable debug mode --help Print usage -H, --host list Daemon socket(s) to connect to -l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info") --tls Use TLS; implied by --tlsverify --tlscacert string Trust certs signed only by this CA (default "/Users/tarun.lalwani/.docker/ca.pem") --tlscert string Path to TLS certificate file (default "/Users/tarun.lalwani/.docker/cert.pem") --tlskey string Path to TLS key file (default "/Users/tarun.lalwani/.docker/key.pem") --tlsverify Use TLS and verify the remote -v, --version Print version information and quit Management Commands: checkpoint Manage checkpoints config Manage Docker configs container Manage containers image Manage images network Manage networks node Manage Swarm nodes plugin Manage plugins secret Manage Docker secrets service Manage services stack Manage Docker stacks swarm Manage Swarm system Manage Docker volume Manage volumes Commands: attach Attach local standard input, output, and error streams to a running container build Build an image from a Dockerfile commit Create a new image from a container's changes cp Copy files/folders between a container and the local filesystem create Create a new container deploy Deploy a new stack or update an existing stack diff Inspect changes to files or directories on a container's filesystem events Get real time events from the server exec Run a command in a running container export Export a container's filesystem as a tar archive history Show the history of an image images List images import Import the contents from a tarball to create a filesystem image info Display system-wide information inspect Return low-level information on Docker objects kill Kill one or more running containers load Load an image from a tar archive or STDIN login Log in to a Docker registry logout Log out from a Docker registry logs Fetch the logs of a container pause Pause all processes within one or more containers port List port mappings or a specific mapping for the container ps List containers pull Pull an image or a repository from a registry push Push an image or a repository to a registry rename Rename a container restart Restart one or more containers rm Remove one or more containers rmi Remove one or more images run Run a command in a new container save Save one or more images to a tar archive (streamed to STDOUT by default) search Search the Docker Hub for images start Start one or more stopped containers stats Display a live stream of container(s) resource usage statistics stop Stop one or more running containers tag Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE top Display the running processes of a container unpause Unpause all processes within one or more containers update Update configuration of one or more containers version Show the Docker version information wait Block until one or more containers stop, then print their exit codes Run 'docker COMMAND --help' for more information on a command.
现在你有组来pipe理多个命令，如container ， image 。 当你运行这个组时
$ docker image Usage: docker image COMMAND Manage images Options: --help Print usage Commands: build Build an image from a Dockerfile history Show the history of an image import Import the contents from a tarball to create a filesystem image inspect Display detailed information on one or more images load Load an image from a tar archive or STDIN ls List images prune Remove unused images pull Pull an image or a repository from a registry 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， docker build是docker container build的别名。 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式，这就是为什么要保持与旧客户端兼容的原因
以前，Docker使用像docker run和docker build这样的命令来运行一个容器或者构build一个图像。 在后来的版本中，他们觉得应该像@ tarun-lalwanibuild议的那样指定并创build一个组，因此在docker docker run或者docker container run没有区别（它们只是彼此的别名）。
