jenkins拉取git仓库代码，执行python脚本

背景：

pytho脚本自动化提交后，自动触发jenkins去构建

1.打开Jenkins新建一个自由风格的项目

源码管理：

Repository URL 代码仓库地址
Credentials git仓库登陆的账号和密码凭证
指定分支（为空时代表any）分支默认*/master

构建job后输出内容

Requirement already satisfied: certifi>=2017.4.17 in /var/jenkins_home/python3/lib/python3.6/site-packages (from requests->-r requirements.txt (line 1)) (2019.11.28)
You are using pip version 18.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

解决办法：

不是看centos下的pip版本

进jenkins容器

docker ps -a

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 -a

2.给pytest加软链接

[root@xiaoxiao ~]# pytest
-bash: pytest: command not found
[root@xiaoxiao ~]#

3.在容器内部查找pytest，find / -name pytest，如果没有，再执行安装pip3 install -U pytest

root@c20362a06289:~# find / -name pytest
root@c20362a06289:~#pip3 install -U pytest 
root@c20362a06289:~# find / -name pytest
/var/jenkins_home/python3/bin/pytest
/var/jenkins_home/python3/lib/python3.6/site-packages/pytest

4.查找pytest安装地址添加软链接,输入pytest --version查看环境

root@c20362a06289:~# ln -s /var/jenkins_home/python3/bin/pytest /usr/bin/pytest
root@c20362a06289:~# pytest --version
This is pytest version 5.4.1, imported from /var/jenkins_home/python3/lib/python3.6/site-packages/pytest/__init__.py
