基本操作命令
Commands:
attach Attach to a running container
# 当前 shell 下 attach 连接指定运行镜像
build Build an image from a Dockerfile # 通过 Dockerfile 定制镜像
commit Create a new image from a container's changes # 提交当前容器为新的镜像
docker commit -m “message”-a “author_name”docker-id new-docker-name:tag
-c,--change=[] 提交时执行dockerfile指令
-p ,--pause=ture:提交时暂停容器运行
cp Copy files/folders from the containers filesystem to the host path
# 从容器中拷贝指定文件或者目录到宿主机中
create Create a new container
# 创建一个新的容器,同 run,但不启动容器
diff Inspect changes on a container's filesystem # 查看 docker 容器变化
events Get real time events from the server # 从 docker 服务获取容器实时事件
exec Run a command in an existing container # 在已存在的容器上运行命令
export Stream the contents of a container as a tar archive
# 导出容器的内容流作为一个 tar 归档文件[对应 import ]
history Show the history of an image # 展示一个镜像形成历史
images List images # 列出系统当前镜像
import Create a new filesystem image from the contents of a tarball
# 从tar包中的内容创建一个新的文件系统映像[对应 export]
info Display system-wide information # 显示系统相关信息
inspect Return low-level information on a container # 查看容器详细信息
docker inspect -f {{“id”}} centos 取容器中的值
kill Kill a running container # kill 指定 docker 容器
load Load an image from a tar archive # 从一个 tar 包中加载一个镜像[对应 save]
docker load -i kubernetes-dashboard.tar
login Register or Login to the docker registry server
# 注册或者登陆一个 docker 源服务器
logout Log out from a Docker registry server # 从当前 Docker registry 退出
logs Fetch the logs of a container # 输出当前容器日志信息
port Lookup the public-facing port which is NAT-ed to PRIVATE_PORT
# 查看映射端口对应的容器内部源端口
pause Pause all processes within a container # 暂停容器
ps List containers # 列出容器列表
--no-trunc 查看完整的容器值
pull Pull an image or a repository from the docker registry server
# 从docker镜像源服务器拉取指定镜像或者库镜像
push Push an image or a repository to the docker registry server
# 推送指定镜像或者库镜像至docker源服务器
restart Restart a running container # 重启运行的容器
rm Remove one or more containers # 移除一个或者多个容器
rmi Remove one or more images
# 移除一个或多个镜像[无容器使用该镜像才可删除,否则需删除相关容器才可继续或 -f 强制删除]
run Run a command in a new container # 创建一个新的容器并运行一个命令
-t - 分配一个(伪)tty (link is external)
-i - 交互模式 (so we can interact with it)
ubuntu:14.04 - 使用 ubuntu 基础镜像 14.04
/bin/bash - 运行命令 bash shell
save Save an image to a tar archive # 保存一个镜像为一个 tar 包[对应 load]
docker save –o docker_image.tar image_name
search Search for an image on the Docker Hub # 在 docker hub 中搜索镜像
--filter=is-automated=true|false:仅显示自动创建的镜像,默认为否。
--filter=stars=x :仅显示评价为指定星级以上的镜像,默认为0,即输出所有镜像。
--no-trunc 输出信息不截断,默认为否。
start Start a stopped containers # 启动容器
stop Stop a running containers # 停止容器
tag Tag an image into a repository # 给源中镜像打标签
top Lookup the running processes of a container # 查看容器中运行的进程信息
unpause Unpause a paused container # 取消暂停容器
version Show the docker version information # 查看 docker 版本号
wait Block until a container stops, then print its exit code
# 截取容器停止时的退出状态值
Run 'docker COMMAND --help' for more information on a command.
查看镜像仓库中应用的tag
通过docker search centos,查看到了centos的镜像,但是不知道仓库中这个镜像有多少可用的tag。通过一下的命令可以查看到。
[admin@controller-server ~]$ curl https://registry.hub.docker.com/v1/repositories/centos/tags| tr -d '[\[\]" ]' | tr '}' '\n'| awk -F: -v image='centos' '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'
