[root@localhost ~]# docker pull ansible/centos7-ansible latest: Pulling from ansible/centos7-ansible 8eeda73d87df: Pull complete 8f137f6d38c1: Pull complete 1a50897796a7: Pull complete 88555f28b7e7: Pull complete 4bbeb012a7d7: Pull complete 3f5df08205ea: Pull complete 9c7646887b8a: Pull complete 719604feb5a5: Pull complete 25a4ad4731e3: Pull complete f240103e8c02: Pull complete 231b24a3be84: Pull complete 231b24a3be84: Pulling fs layer 47d44cb6f252: Already exists f6f39725d938: Already exists f9a8cbc8dd13: Already exists f37e6a610a37: Already exists Digest: sha256:4c949411e556a423d6e95affda4908d4d295f3a5d59443925e9db30c400473ac Status: Downloaded newer image for ansible/centos7-ansible:latest
4.查看所有Docker镜像
[root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE ansible/centos7-ansible latest 231b24a3be84 11 hours ago 400.5 MB centos latest 0f73ae75014f 2 days ago 172.3 MB ubuntu latest 91e54dfb1179 2 weeks ago 188.3 MB
5.启动、关闭容器
[root@localhost ~]# docker start bea707b2a8fe bea707b2a8fe [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES bea707b2a8fe centos:latest "/bin/bash" About an hour ago Up 7 seconds gloomy_lovelace
[root@localhost ~]# docker stop bea707b2a8fe bea707b2a8fe [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
docker ps是查看正在运行中的容器
6.docker镜像的导入
cat centos.tar | docker import - centos6
7.docker镜像的导出
[root@localhost ~]# docker export b277a4166ab8 >centosipshow [root@localhost ~]# find / -name centosipshow /root/centosipshow
8.运行centos容器输出“hello，world”
[root@localhost ~]# docker images | grep centos ansible/centos7-ansible latest 231b24a3be84 11 hours ago 400.5 MB centos latest 0f73ae75014f 2 days ago 172.3 MB [root@localhost ~]# docker run centos:latest echo "hello,world" hello,world
9.查看centos latest的版本信息和网络信息
[root@localhost ~]# docker run centos:latest cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
[root@localhost ~]# docker run centos:latest ip addr show
22: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
link/ether 02:42:ac:11:00:07 brd ff:ff:ff:ff:ff:ff

10.在容器里启动一个交互式容器
[root@localhost ~]# docker run -i -t centos:latest /bin/bash [root@bea707b2a8fe /]# cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core)
-t 表示打开一个终端的意思，-i表示可以交互输入
11.创建一个后台型容器
[root@localhost ~]# docker run -d centos:latest /bin/bash -c "while true;do echo hello;sleep 1;done " 90eab2a7e8ececb30882627363407b471a4f0119f8771091bf45023d09bff10d [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 90eab2a7e8ec centos:latest "/bin/bash -c 'while 7 seconds ago Up 3 seconds naughty_pike 2b3347837a45 ubuntu "/bin/bash -c 'while About an hour ago Up About an hour modest_brattain [root@localhost ~]# docker attach 90eab2a7e8ec hello hello hello
