docker基本命令

1.<image>:<tag>    tag指定镜像版本号，默认为latest,指定非latest版本号可以避免latest更新带来的潜在问题。
2.docker search <image>    从远程仓库查找镜像，默认官方仓库docker.io,可以指定其它，例如自己的私有库。
3.docker pull <image>   从远程仓库获取镜像。
4.docker build   .   构建镜像。

  -t <image> 指定镜像名称和版本号  -f <Dockerfile> 指定Dockerfile文件位置，默认当前目录下的Dockerfile文件

5.docker ps   查看当前运行的容器状态。

  -a 查看所有容器的运行状态

6.docker start/stop/restart <containerID>   启动停止容器
7.docker rm <containerID>    删除容器
8.docker run <image>   通过镜像生成容器并运行，默认寻找本地镜像，本地无镜像会下载远程镜像。

  -d  容器保持后台运行  -it  前台运行并可以直接操作容器，与-d只能存在一个  --name <container>  生成的容器名称，默认随机名称  -p <hostIP>:<containerIP> 指定本地端口和容器内端口的对应关系  --link <linkContainer>:<alias>  将当前容器连接到其它运行的容器，alias为连接容器的别称，当前容器可以通过alias连接到其它容器中的数据库  -v <hostPosition>;:<containerPositon>  宿主机与容器内的位置对应，容器销毁后里面的数据也会消失，需要保留的数据需要存放在宿主机  --restart   no 不重启  on-failure 退出状态非0时重启 always 始终重启

9.docker attach <container>
docker exec -it <container> /bin/sh
进入一个正在运行的容器，ctrl+p+q退出容器

10.docker tag &lt;imageID> <image>:<tag>   根据现有镜像ID生成新镜像并指定tag
11.docker rmi <imageID>    删除镜像
12.docker login    登录远程仓库
13.docker push <Image>    将本地镜像发布到远程仓库
14.docker cp foo.txt mycontainer:/foo.txt 将本地文件拷贝到容器
15.docker cp mycontainer:/foo.txt foo.txt 将容器内文件拷贝到本地
16.docker logs -f 查看容器内日志
