# 运行某镜像(如果不存在会远程下载)
docker run hello-world
eg:
运行centos:centos6的容器并执行输出一段文字，之后退出
docker run centos:centos6 echo "hello world"


# 下载某镜像
docker pull centos:centos6

# 运行并进入bash环境
-i 容器的标准输入保持打开 -t 让Docker分配一个伪终端（pseudo-tty）并绑定到容器的标准输入上
docker run -i -t centos:centos6 /bin/bash

# 运行时将宿主文件夹挂载到/data
docker run -it -v /tmp:/data centos:centos6 /bin/bash

# 守护方式运行
docker run -idt centos-base

# 容器任务管理器
docker ps -a

# 进入容器
docker attach 3ca3de3b8b6a

# 导出容器
docker export 3ca3de3b8b6a > centos6-base.tar

# 导入容器并明命名
cat centos6-base.tar > docker import - centos-new_base

# 直接导入某镜像文件
docker import http://example.com/some_image.tgz

# 删除容器
docker rm 3ca3de3b8b6a

# 查看所有镜像
docker images

# 提交镜像
docker commit 3ca3de3b8b6a centos-new_base

# 删除镜像
docker rmi centos-new_base

# 停止当前运行着的container
docker kill $(docker ps -a -q)

# 删除没有在运行的container
docker rm $(docker ps -a -q)
