jenkins新建一个工程

1.新建一个jenkins项目

 

 

 2.设置构建环境

 

 

 3.构建job后控制台输出内容

 

 

pip3: not found，说明jenkins容器内部并没有python3的环境

4.进jenkins容器

进docker容器, 加上-u root 以root用户权限进入容器

docker exec -it -u root 容器id /bin/bash

[root@xiaoxiao ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED 
c20362a06289 jenkins/jenkins:lts "/sbin/tini -- /usr/…" 40 hours ago
[root@xiaoxiao ~]# docker exec -it -u root c20362a06289 /bin/bash
root@c20362a06289:/# uname -a
Linux c20362a06289 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 GNU/Linux
root@c20362a06289:/# cat /etc/issue
Debian GNU/Linux 9 \n \l

root@c20362a06289:/#

这里查到的是Debian系统（不是ubuntu， 也不是centos），这里yum是没有的，所以不能用yum安装了，这里用apt-get代替yum
先执行更新apt-get

apt-get update

5.容器内部安装python3环境

下载python3安装包

进入容器内部, linux安装python3环境,参考这篇https://www.cnblogs.com/june-/articles/11929870.html

root@c20362a06289:/# cd /var/jenkins_home
root@c20362a06289:/var/jenkins_home# mkdir python3

root@c20362a06289:/var/jenkins_home/python3/Python-3.6.8#

执行 ./configure --prefix=/var/jenkins_home/python3时报上面错：configure: error: no acceptable C compiler found in $PATH

6.apt-get 安装依赖包

这个是因为缺少gcc相关依赖包，使用apt-get代替yum安装相关依赖包

apt-get -y install gcc automake autoconf libtool make
apt-get -y install make*
apt-get -y install zlib*
apt-get -y install openssl libssl-dev
apt-get install sudo

7.make编译安装

在/var/jenkins_home/python3/Python-3.6.8目录执行make和make install 安装

./configure --prefix=/var/jenkins_home/python3 --with-ssl
make
make install

8.添加软链接

添加python3软链接

ln -s /var/jenkins_home/python3/bin/python3.6 /usr/bin/python3

添加pip3软链接

ln -s /var/jenkins_home/python3/bin/pip3 /usr/bin/pip3

9.检查环境

root@c20362a06289:/var/jenkins_home/python3/Python-3.6.8# pip3

root@c20362a06289:/var/jenkins_home/python3/Python-3.6.8# python3
Python 3.6.8 (default, Apr 2 2020, 09:04:42) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

使用pip3安装一个requests包

pip3 install requests

我这里安装正常。

10.验证构建project
