docker --help- Docker基本语法；
Usage: docker [OPTIONS] COMMAND [arg...] docker daemon [ --help | ... ] docker [ --help | -v | --version ]A self-sufficient runtime for containers.- 选项；
Options: # 指定Docker客户端配置文件的路径； --config=~/.docker Location of client config files # 是否使用Debug模式，默认为false； -D, --debug Enable debug mode # 在daemon模式下绑定的socket，通过一个或多个 tcp://host:port, unix:///path/to/socket, fd://* or fd://socketfd来指定； -H, --host=[] Daemon socket(s) to connect to # 查看帮助信息，-h 和 --help 是一样的； -h, --help Print usage # 设置日志等级，-l 和 --log-level 是一样的； -l, --log-level=info Set the logging level # 是否开启tls，默认为false； --tls Use TLS; implied by --tlsverify # 指定CA(Certificate Authority认证授权机构)签名的信任证书的路径； --tlscacert=~/.docker/ca.pem Trust certs signed only by this CA # 指定TLS证书文件的路径； --tlscert=~/.docker/cert.pem Path to TLS certificate file # 指定TLS公钥文件的路径； --tlskey=~/.docker/key.pem Path to TLS key file # 使用TLS并验证远程控制主机； --tlsverify Use TLS and verify the remote # 输出Docker的版本信息(简略)并退出 -v, --version Print version information and quit- 命令；
Commands: # 依附到一个正在运行的容器中； attach Attach to a running container # 依据Dockerfile文件构建镜像； build Build an image from a Dockerfile # 在容器中将容器构建为一个新的镜像； commit Create a new image from a container's changes # 在容器和宿主机之间拷贝文件/文件夹； cp Copy files/folders between a container and the local filesystem # 创建容器； create Create a new container # 检查一个容器的文件系统的变更； diff Inspect changes on a container's filesystem # 从服务端获取实时的事件； events Get real time events from the server # 在运行的容器中执行命令； exec Run a command in a running container # 将一个容器的文件系统导出为一个tar包； export Export a container's filesystem as a tar archive # 显示一个镜像的构建历史信息(镜像的构建步骤记录-类似Dockerfile)； history Show the history of an image # 查询镜像列表； images List images # 从tarball导入内容创建一个文件系统映像； import Import the contents from a tarball to create a filesystem image # 显示整个系统的信息； info Display system-wide information # 获取容器或镜像的低级信息； inspect Return low-level information on a container or image # 关闭一个正在运行的容器(包括进程和所有相关资源)； kill Kill a running container # 从一个tar包或STDIN中加载一个镜像； load Load an image from a tar archive or STDIN # 登陆Docker注册服务器(上传镜像需要先登录)； login Log in to a Docker registry # 登出Docker注册服务器(注销)； logout Log out from a Docker registry # 获取一个容器的日志信息； logs Fetch the logs of a container # 管理容器的网络配置； network Manage Docker networks # 暂停一个容器内的所有进程； pause Pause all processes within a container # 列出一个容器的端口映射或一个特定映射的信息； port List port mappings or a specific mapping for the CONTAINER # 列出所有的容器； ps List containers # 从注册服务器的仓库中拉取一个镜像； pull Pull an image or a repository from a registry # 向注册服务器的仓库中上传一个镜像； push Push an image or a repository to a registry # 将一个容器重命名； rename Rename a container # 重启一个容器； restart Restart a container # 删除一个或多个容器； rm Remove one or more containers # 删除一个或多个镜像； rmi Remove one or more images # 在一个新的容器中运行一个命令； run Run a command in a new container # 将一个或多个镜像保存为一个tar包； save Save one or more images to a tar archive # 在Docker Hub中搜索镜像； search Search the Docker Hub for images # 启动一个或多个暂停的容器； start Start one or more stopped containers # 动态显示容器资源的使用情况；例如“docker stats 8981”信息如下： # CONTAINER CPU % MEM USAGE/LIMIT MEM % NET I/O BLOCK I/O PIDS # 8981 0.00% 3.551MB/4.145GB 0.09% 509.6kB/14.15MB 2.028MB/0 B 0 stats Display a live stream of container(s) resource usage statistics # 停止一个正在运行的容器； stop Stop a running container # 修改本地仓库中镜像的标签； tag Tag an image into a repository # 显示一个容器中正在运行的进程； top Display the running processes of a container # 解除一个容器中所有进程的暂停状态； unpause Unpause all processes within a container # 更新一个或多个容器的配置； update Update configuration of one or more containers # 显示Docker的版本信息(详细) version Show the Docker version information # 管理Docker的数据卷； volume Manage Docker volumes # 阻塞,直到一个容器停止,然后输出它的退出代码 wait Block until a container stops, then print its exit code# 运行“docker COMMAND --help”获取更多的指令信息，如指令的用途与参数的详细解释。Run 'docker COMMAND --help' for more information on a command.- 举例说明；
