5、启动服务


/etc/init.d/docker start
[ ok ] Starting docker (via systemctl): docker.service.


6、拉取debian和CentOS镜像
1)拉取debian镜像


docker pull debian
latest: Pulling from debian
843e2bded498: Pull complete 
8c00acfb0175: Pull complete 
debian:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.
Digest: sha256:d9168a2c1889b4c9d44952a23065c29b0656237909d618328275f42065602354
Status: Downloaded newer image for debian:latest


2)拉取centos镜像


docker pull centos
Pulling repository centos
0f73ae75014f: Download complete 
47d44cb6f252: Download complete 
f6f39725d938: Download complete 
f9a8cbc8dd13: Download complete 
f37e6a610a37: Download complete 
Status: Downloaded newer image for centos:latest


7、查看镜像


docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
debian latest 8c00acfb0175 3 weeks ago 125.2 MB
centos latest 0f73ae75014f 3 weeks ago 172.3 MB


8、运行名为debian镜像的容器(虚拟


docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
debian latest 8c00acfb0175 3 weeks ago 125.2 MB
centos latest 0f73ae75014f 3 weeks ago 172.3 MB


出1个debian系统)
1)运行debian镜像的容器


docker run -i -t debian


2)查看版本


root@10.1.10.236:~# docker run debian cat /etc/debian_version
8.2


3)查看IP(是dhcp获得 每次获得都不一样)


root@10.1.10.236:~# docker run debian ip 
a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host 
valid_lft forever preferred_lft forever
24: eth0: <NO-CARRIER,BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state DOWN group default 
link/ether 02:42:ac:11:00:0b brd ff:ff:ff:ff:ff:ff

valid_lft forever preferred_lft forever
inet6 fe80::42:acff:fe11:b/64 scope link tentative 
valid_lft forever preferred_lft forever


4)查看内核


root@10.1.10.236:~# docker run debian uname -r
3.16.0-4-amd64


5)查看硬盘分区情况


root@10.1.10.236:~# docker run -i -t debian df -Th
Filesystem Type Size Used Avail Use% Mounted on
none aufs 9.1G 1.6G 7.1G 18% /

shm tmpfs 64M 0 64M 0% /dev/shm
/dev/sda1 ext4 9.1G 1.6G 7.1G 18% /etc/hosts


9、运行名为centos镜像的容器(虚拟出1个centos系统)
1)运行centos镜像的容器


docker run -i -t centos


2)查看版本


root@10.1.10.236:~# docker run centos cat /etc/RedHat-release
CentOS Linux release 7.1.1503 (Core)


3)查看内核


root@10.1.10.236:~# docker run centos uname -r
3.16.0-4-amd64


4)查看ip


root@10.1.10.236:~# docker run centos ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

valid_lft forever preferred_lft forever
inet6 fe80::42:acff:fe11:16/64 scope link tentative 
valid_lft forever preferred_lft forever


5)查看硬盘分区情况


root@10.1.10.236:~# docker run centos df -Th
Filesystem Type Size Used Avail Use% Mounted on
