jenkins学习5-jenkins拉取git仓库代码，执行python自动化脚本

前言

python自动化的脚本开发完成后需提交到git代码仓库，接下来就是用Jenkins拉取代码去构建自动化代码了

git源码管理

代码上传git仓库这里就不介绍了，可以看之前写过的github相关这篇https://www.cnblogs.com/yoyoketang/p/7302515.html
自己公司内部的一般用gitlab,可以参考这篇https://www.cnblogs.com/yoyoketang/p/10282529.html

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

Repository URL 代码仓库地址

备注：如果是ssh方式链接的，就点右上角的SSH地址

Credentials 点开Jenkins按钮，输入git仓库登陆的账号和密码

构建 执行shell

执行shell,先pip3安装requirements.txt,再用pytest执行脚本

查看控制台输入出，console查看日志

+ ls
requirements.txt
test_demo.py
+ pip3 install -r requirements.txt
Collecting requests==2.18.4 (from -r requirements.txt (line 1))
  Downloading 

Installing collected packages: idna, urllib3, requests, atomicwrites, six, more-itertools, wcwidth, attrs, py, zipp, importlib-Metadata, pluggy, pytest, pytest-Metadata, pytest-html
  Found existing installation: idna 2.8
    Uninstalling idna-2.8:
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/var/jenkins_home/python3/lib/python3.6/site-packages/idna-2.8.dist-info/INSTALLER'
Consider using the `--user` option or check the permissions.

发现没有权限安装，可以进入容器内部安装

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

打开workspace目录安装 /home/jenkins/workspace/pytest_demo

[root@cb8e397d5308]# cd /home/jenkins/workspace/pytest_demo
[root@cb8e397d5308]# ls
requirements.txt  test_demo.py
[root@cb8e397d5308]# pip3 install -r requirements.txt

安装完成后输入pytest检查pytest:-bash: pytest: command not found

[root@VM_0_2_centos pytest_demo]# pytest
-bash: pytest: command not found

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

[root@cb8e397d5308]# find / -name pytest
/var/jenkins_home/python3/bin/pytest
[root@cb8e397d5308]# ln -s /var/jenkins_home/python3/bin/pytest /usr/bin/pytest
[root@cb8e397d5308]# pytest --version

  pytest-Metadata-1.8.0 at /root/python36/lib/python3.6/site-packages/pytest_Metadata/plugin.py

构建job

上面需要的环境都安装完成后，执行shell的时候，直接输入pytest命令就可以执行自动化的脚本了

构建成功
