简介： 云原生之使用docker部署centos系统测试环境

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
Client: Docker Engine - Community
 Version:           20.10.17
 API version:       1.41
 Go version:        go1.17.11
 Git commit:        100c701

 OS/Arch:           linux/amd64
 Context:           default
 Experimental:      true

Server: Docker Engine - Community

  GitCommit:        de40ad0

三、检查docker状态

[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2022-11-04 09:12:32 CST; 18h ago

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

Complete!

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
        ether 02:42:ac:11:00:06  txqueuelen 0  (Ethernet)
        RX packets 7037  bytes 25618849 (24.4 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 4655  bytes 269171 (262.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        loop  txqueuelen 1000  (Local Loopback)
        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)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

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.

6 packets transmitted, 6 received, 0% packet loss, time 5010ms
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
