1. docker search [名称]
从仓库中查找镜像 eg: docker search jdk
NAME：镜像仓库名
DESCRIPTION：描述信息
STARS：和Github的Star一个道理
OFFICIAL：是否官方镜像
AUTOMATED：是否由Docker Hub自动构建2. docker pull [名称]
从仓库中下载镜像 eg: docker pull docker.io/codenvy/jdk8_maven3_tomcat8
这样就下载完成了。
3. docker images
查看本地所有镜像 eg: docker images
REPOSITORY：镜像仓库的名字
TAG：该镜像的版本号
IMAGE ID：镜像的ID
CREATED：创建时间
SIZE：镜像的大小4. docker run --name 容器名 -i -t 镜像ID /bin/bash
该命令会基于指定镜像创建一个新的容器
–name：为容器设置一个名字
-i -t：使得容器启动后能获取该容器的shell
镜像ID：指定容器要基于哪一个镜像运行
最后一个参数是运行时需要需要执行的命令，这里执行/bin/bash使得容器运行后启动一个bash供我们和容器交互。eg: docker run --name jdk8_maven3_tomcat8 -i -t 0cec97ba8d8a /bin/bash
启动后我们将进入容器内部，获得一个用于和容器交互的shell，我们可以在这里对容器作任何操作，并且和操作一台Linux系统没有任何区别。
5. docker ps -a
查看已经创建的容器
-a：能查看所有已经被创建的容器；不加这个参数仅会显示正在运行的容器。
CONTAINER ID：该容器的ID
IMAGE：该容器使用的镜像
COMMAND：启动时执行的命令
CREATED：容器创建时间
STATUS：当前运行状态
PORTS：该容器所开启的端口号
NAMES：容器的名字6. docker start 容器名
启动已经创建的容器
该命令执行后容器会在后台运行，只返回一个容器名，若需要获取容器交互式shell，需要继续执行 7 命令。
7. docker attach 容器名 或者 docker exec -it 容器ID /bin/bash
进入容器内部，并获取了容器的shell
8. docker inspect 容器名
获取容器参数。
上述指令可以查看指定容器的所有配置信息，这些信息以JSON的形式返回，如下：

]可以使用-f或–format参数指定查看某一个参数：（建议使用）
docker inspect --format='{{.NetworkSettings.IPAddress}}' 容器名
9. 容器内执行命令
a.如果你已经进入容器内部，并获取了容器的shell，那么就执行执行命令即可；
b.如果容器在后台运行，那么你可以通过 docker exec 命令直接在宿主机上执行某个容器的命令
eg: docker exec [参数] 容器名 命令
上述命令会在指定的容器中执行指定的命令。
如果你的命令无需交互，那么需要在参数部分加上-d，使得该命令在容器后台执行即可；
如果你的命令在执行过程中需要用户输入，那么需要在参数部分加上-i -t，
并使用命令：/bin/bash，从而你就能进入容器内部，获取一个交互式的shell。
10. 停止容器
a. 当你在容器内部，只要执行exit命令即可停止并退出容器。
b.当容器处于后台运行的状态，你需要通过如下命令停止容器： docker stop 容器名
11. docker rm 容器名
删除容器
