sudo docker rmi 镜像
sudo docker rmi 8dde5631d4aaDocker 容器命令
根据镜像创建容器，并启动
如果镜像把比作类，则容器就是对象。通过镜像创建容器
hry@hry-VirtualBox:~$ sudo docker run --name test_redis -itd 1a8a9ee54eb7
64024a8a158b276f6a8c5069343cf862add88d2e52e80537246449894a47e768启动参数
- –name参数是为容器取得名称
- -i：表示以“交互模式”运行容器
- -t：表示容器启动后会进入其命令行
- -d：参数能让一个容器以守护态运行
查看运行中的容器列表

因为容器中运行的软件所使用的端口，在本机和本机的局域网是不能访问的，所以将docker容器中的端口映射到当前的端口上。
映射容器的6379端口到本机的6378端口，如下
docker run -d -p 6378:6379 --name port-redis redis#### 删除容器
删除单个容器
sudo docker rm container-id删除所有容器
sudo docker rm `sudo docker ps -a -q`
