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 <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
