### 查找指定镜像
docker search ubuntu
### 拉取镜像
docker pull ubuntu
### 查看镜像列表
docker images
### 删除镜像
docker rmi 7aa3095f0856
删除镜像需要先删除使用镜像的容器
0x04 container
启动镜像
### 以名称+标签形式启动
docker run -t -i ubuntu:latest /bin/bash
docker run hello-world /hello
### 以ID启动
docker run fce289e99eb9 /hello
-t：在该容器中启动一个新的终端 -i：通过容器中的标准输入流建立交互式连接
如果想要退回到宿主机的终端，并且不中断该容器的执行，可以按下 CTRL+P，再按下 CTRL+Q。现在，你就安全的返回到了你的宿主机系统中。需要注意的是，Docker 容器仍然在后台运行，我们并没有中断它。
