1、使用交互式方式運行容器，可以和容器進行對話
[dkuser@c741 ~]$ docker run -i -t ubuntu:15.10 /bin/bash
這時候就已經進入容器內部了。
參數說明：
-t:在新容器內指定一個僞終端或終端。
-i:允許你對容器內的標準輸入 (STDIN) 進行交互。
2、更新出錯解決
root@4e09338995bd:/# apt-get update
Ign http://archive.ubuntu.com wily InRelease
Ign http://archive.ubuntu.com wily-updates InRelease
Ign http://archive.ubuntu.com wily-security InRelease
Ign http://archive.ubuntu.com wily Release.gpg
Ign http://archive.ubuntu.com wily-updates Release.gpg

解決：
容器源配置
root@4e09338995bd:/# cp /etc/apt/sources.list /etc/apt/sources.list.bak
root@4e09338995bd:/# sed -i -r 's/([a-z]{2}\.)?archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
root@4e09338995bd:/# sed -i -r 's/security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
更新成功

3、安裝工具
因爲不能使用ifconfig和ping等命令，所以安裝基礎包。
如果不知道命令是那個包的可以使用下面命令查看
root@4e09338995bd:/# apt-file search bin/ifconfig
root@4e09338995bd:/# apt install net-tools
root@4e09338995bd:/# apt install iputils-ping
root@4e09338995bd:/# apt-get install network-manager
4、查看容器主機網絡等信息
root@4e09338995bd:/# ifconfig
eth0 Link encap:Ethernet HWaddr 02:42:ac:11:00:02
inet addr:172.17.0.2 Bcast:172.17.255.255 Mask:255.255.0.0

查看dns地址
root@c741:/# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 114.114.114.114
5、生成新的鏡像
exit 退出容器
查看生成的容器
[dkuser@c741 ~]$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4e09338995bd ubuntu:15.10 "/bin/bash" 2 hours ago Exited (130) 32 minutes ago hopeful_roentgen
把容器生成新的鏡像
[dkuser@c741 ~]$ docker commit -m "ubuntu:15.10_with_basis_env" -a "sxzhou" 4e09338995bd ubuntu:15.10_basis_env
參數說明：
-m：說明信息
-a：創建者
查看生成的鏡像
[dkuser@c741 ~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu 15.10_basis_env 6422827a9898 23 seconds ago 492MB
ubuntu 15.10 9b9cb95443b5 2 years ago 137MB
