基于国产化龙蜥8.6基础容器镜像制作支持ssh、telnet、python3的扩展容器镜像

2023-12-20 14:56:52

国产化服务器操作系统比较主流的就是欧位和龙蜥,容器化环境考虑到兼容性问题,可以选择与centos全兼容的龙蜥系列。本文记录了基于龙蜥8.6基础镜像加装ssh、telnet、python3的过程。

一、拉取镜像

1、查找龙蜥基础镜像,使用docker search anolisos,可以看到官方基础镜像为openanolis/anolisos:

# docker search anolisos

2、考虑兼容性及手头上有的操作系统ISO文件,经测试,8.6版anolisos可用,拉取并保存镜像:

[root@localhost dockerfile]# docker pull openanolis/anolisos:8.6
8.6: Pulling from openanolis/anolisos
719018114380: Pull complete 
Digest: sha256:9395d241fc1a41a592773629994c3c0fa48886dd99c75431d7a885fb842753fa
Status: Downloaded newer image for openanolis/anolisos:8.6
[root@localhost dockerfile]# docker images |grep anolisos    
openanolis/anolisos     8.6                 6f8a2912d1d7        16 months ago       205MB
[root@localhost dockerfile]# docker save -o anolisos8.6.tar openanolis/anolisos:8.6
[root@localhost dockerfile]# ll anolisos8.6.tar        
-rw------- 1 root root 202M 12月 20 09:26 anolisos8.6.tar

二、导入并测试镜像?

3、在目标服务器上将启动容器脚本写入文本,导入保存的镜像文件,运行脚本启动容器:

# vi 0-mkdocker-anolisos.sh
# cat 0-mkdocker-anolisos.sh 
docker run -itd --restart=always --name anolisos --privileged  -v /data/dockerdata:/opt -v /etc/localtime:/etc/localtime:ro openanolis/anolisos:8.6 /usr/sbin/init
# docker load -i anolisos8.6.tar 
068524d0c0b6: Loading layer [==================================================>]  211.2MB/211.2MB
Loaded image: openanolis/anolisos:8.6
# sh 0-mkdocker-anolisos.sh 
77af622f6696d6a0cfc4d5a99109139e91b9238de6491c3b537562215c355b58

4、进入容器,查看容器内系统版本信息,并查看ssh、python、python3的安装情况

# docker exec -it anolisos /bin/bash
[root@77af622f6696 /]# cat /etc/os-release 
NAME="Anolis OS"
VERSION="8.6"
ID="anolis"
ID_LIKE="rhel fedora centos"
VERSION_ID="8.6"
PLATFORM_ID="platform:an8"
PRETTY_NAME="Anolis OS 8.6"
ANSI_COLOR="0;31"
HOME_URL="https://openanolis.cn/"

[root@77af622f6696 /]# ssh -V
bash: ssh: command not found
[root@77af622f6696 /]# python --version
bash: python: command not found
[root@77af622f6696 /]# python3 --version
bash: python3: command not found

可见基础镜像中ssh、python、python3均未安装

三、给容器加装软件

1、修改repo文件将yum指向内网服务器,并依次安装所需软件:

[root@77af622f6696 /]# cd /etc/yum.repos.d/ 
[root@77af622f6696 yum.repos.d]# rm * -rf
[root@77af622f6696 yum.repos.d]# vi http.repo
[root@77af622f6696 yum.repos.d]# cat http.repo 
[Appstream]

baseurl=http://192.168.122.226/AnolisOS/AnolisOS8.6U1/AppStream/

Complete!

本例完成了openssh-clients、telnet、python3的安装,其中ssh客户端为OpenSSH_8.0p1,python为3.6.8。

2、测试通过pip3加装python的扩展包

[root@77af622f6696 ~]# pip3 install ptyprocess-0.7.0-py2.py3-none-any.whl  pexpect-4.9.0-py2.py3-none-any.whl                                      WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
Processing ./ptyprocess-0.7.0-py2.py3-none-any.whl
Processing ./pexpect-4.9.0-py2.py3-none-any.whl
Installing collected packages: ptyprocess, pexpect
Successfully installed pexpect-4.9.0 ptyprocess-0.7.0

测试成功。

3、添加ll别名,因为习惯使用ll别名,因此在镜像中添加别名:

[root@77af622f6696 ~]# ll
bash: ll: command not found
[root@77af622f6696 ~]# vi ~/.bashrc
[root@77af622f6696 ~]# cat ~/.bashrc |grep ll
alias ll='ls -alF'
[root@77af622f6696 ~]# alias ll='ls -alF'
[root@77af622f6696 ~]# ll
total 24
dr-xr-x---. 1 root root  42 Dec 20 11:03 ./
drwxr-xr-x. 1 root root  62 Dec 20 10:01 ../
-rw-------. 1 root root 614 Dec 20 10:47 .bash_history
-rw-r--r--. 1 root root  18 Jan 27  2021 .bash_logout
-rw-r--r--. 1 root root 176 Jan 27  2021 .bash_profile
-rw-r--r--. 1 root root 195 Dec 20 11:03 .bashrc
-rw-r--r--. 1 root root 100 Jan 27  2021 .cshrc
-rw-r--r--. 1 root root 129 Jan 27  2021 .tcshrc
[root@77af622f6696 ~]# 

四、将容器打包成镜像并导出

# docker ps
CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS              PORTS               NAMES
77af622f6696        openanolis/anolisos:8.6   "/usr/sbin/init"    About an hour ago   Up About an hour                        anolisos
# docker commit -m "anolisos:8.6 with ssh telnet python3" -a "daijianbing"  77af622f6696  anolisos:8.6v2                    
sha256:05202b3da6d8a06f423a37ffed4b69457c9f344522f0c840703a3824f5379cb7
# docker images|grep anolis

openanolis/anolisos     8.6                 6f8a2912d1d7        16 months ago       205MB
# docker save -o anolisos-8.6v2.tar anolisos:8.6v2
# ll an*
-rw-r-----. 1 root root 202M 12月 20 09:52 anolisos8.6.tar
-rw-------. 1 root root 250M 12月 20 10:52 anolisos-8.6v2.tar

打包后的镜像即可进行分发了。
