Docker 容器
在上一章节中我们使用 docker run
命令运行了一个 Hello World
开启了 Docker
容器的使用
每次遇到这种新的技术,我都有一个待解问题,到底有多少命令,我要怎么使用它们
那么,Docker 中到底有多少命令呢?
docker
命令
上一章节中我们所使用的所有命令都以 docker
开头,那如果直接运行 docker
命令会怎么样呢?
答案就是列出 Docker 所支持的所有命令
[root@localhost ~]# docker Usage: docker COMMAND A self-sufficient runtime for containers Options: --config string Location of client config files (default "/Users/luojianguo/.docker") -D, --debug Enable debug mode -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/luojianguo/.docker/ca.pem") --tlscert string Path to TLS certificate file (default "/Users/luojianguo/.docker/cert.pem") --tlskey string Path to TLS key file (default "/Users/luojianguo/.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 swarm Manage Swarm system Manage Docker trust Manage trust on Docker images 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.
很长的命令列表,不过只要关注最后一行就好了
大概意思是说可以通过命令 docker command --help 更深入的了解指定的 Docker 命令使用方法
例如我们要查看 docker stats 指令的具体使用方法
可以输入如下的命令
[root@localhost ~]# docker stats --help Usage: docker stats [OPTIONS] [CONTAINER...] Display a live stream of container(s) resource usage statistics Options: -a, --all Show all containers (default shows just running) --format string Pretty-print images using a Go template --no-stream Disable streaming stats and only pull the first result --no-trunc Do not truncate output
