jenkins學習5-jenkins拉取git倉庫代碼，執行python自動化腳本

前言

python自動化的腳本開發完成后需提交到git代碼倉庫，接下來就是用Jenkins拉取代碼去構建自動化代碼了

git源碼管理

代碼上傳git倉庫這里就不介紹了，可以看之前寫過的github相關這篇https://www.cnblogs.com/yoyoketang/p/7302515.html
自己公司內部的一般用gitlab,可以參考這篇https://www.cnblogs.com/yoyoketang/p/10282529.html

打開Jenkins新建一個自由風格的項目

源碼管理

• Repository URL 代碼倉庫地址
• Credentials git倉庫登陸的賬號和密碼憑證
• 指定分支（為空時代表any）分支默認*/master

Repository URL 代碼倉庫地址

備注：如果是ssh方式鏈接的，就點右上角的SSH地址

Credentials 點開Jenkins按鈕，輸入git倉庫登陸的賬號和密碼

構建 執行shell

執行shell,先pip3安裝requirements.txt,再用pytest執行腳本

查看控制台輸入出，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

    Uninstalling idna-2.8:

Consider using the `--user` option or check the permissions.

發現沒有權限安裝，可以進入容器內部安裝

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

打開workspace目錄安裝 /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

安裝完成后輸入pytest檢查pytest:-bash: pytest: command not found

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

查找pytest安裝地址添加軟鏈接,輸入pytest --version查看環境

[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

構建job

上面需要的環境都安裝完成后，執行shell的時候，直接輸入pytest命令就可以執行自動化的腳本了

構建成功
