一、检查本地服务器系统版本
[root@node ~]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"
[root@node ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
二、检查docker版本
[root@node ~]# docker version

三、检查docker状态
[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine

四、下载centos镜像
[root@node ~]# docker pull centos:7
7: Pulling from library/centos
Digest: sha256:9d4bcbbb213dfd745b58be38b13b996ebb5ac315fe75711bd618426a630e0987
Status: Image is up to date for centos:7
docker.io/library/centos:7
五、创建centos容器
1.运行cnentos容器
[root@node ~]# docker run -it --name centos_test centos:7 /bin/bash
[root@db4f4dfa3a84 /]#
2.进入容器内
[root@node ~]# docker run -it --name centos_test centos:7 /bin/bash
[root@db4f4dfa3a84 /]# ls
anaconda-post.log bin dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
[root@db4f4dfa3a84 /]# pwd
/
六、centos容器内部测试
1.安装ifconfig命令的软件包
[root@db4f4dfa3a84 /]# yum -y install net-tools
Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile

2.查看容器内IP地址
[root@db4f4dfa3a84 /]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.17.0.6 netmask 255.255.0.0 broadcast 172.17.255.255

RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)

3.测试与宿主机网络连通情况
[root@db4f4dfa3a84 /]# ping 192.168.3.166 -c 6
PING 192.168.3.166 (192.168.3.166) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.075/0.100/0.130/0.018 ms
4.让centos容器后台运行
从容器退出，但不停止容器: Ctrl+P+Q
[root@node ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
db4f4dfa3a84 centos:7 "/bin/bash" 11 minutes ago Up 11 minutes centos_test
