python有jenkins獲取配置檔案的api,也有修改配置檔案的api,
下面介紹下 如果修改jenkins job的配置檔案內容:
import re import time import jenkins jenkins_url="http://xxx.com/jenkins" username="zhangsan" token="1.......de" jenkins = jenkins.Jenkins(jenkins_url,username,token) #新增 舊構建記錄預設配置 daysToKeep = "20" numToKeep = "10" str = '<properties>\n' + \ '<jenkins.model.BuildDiscarderProperty>\n' + \ '<strategy class="hudson.tasks.LogRotator">\n' + \ '<daysToKeep>'+daysToKeep+'</daysToKeep>\n' + \ '<numToKeep>'+numToKeep+'</numToKeep>\n' + \ '<artifactDaysToKeep>-1</artifactDaysToKeep>\n' + \ '<artifactNumToKeep>-1</artifactNumToKeep>\n' + \ '</strategy>\n' + \ '</jenkins.model.BuildDiscarderProperty>' # 獲取jenkins中所有job的名字 all_jobs=jenkins.get_jobs() for job in all_jobs: job_name = job["name"] job_confogure_data = jenkins.get_job_config(job_name) # 獲取job congifure info if job_confogure_data.find("jenkins.model.BuildDiscarderProperty") == -1: # 如果這個job沒有勾選 構建舊記錄的配置策略 job_confogure_data = re.sub("<properties>", str, job_confogure_data, 1) # 需修改第一個<properties> else: job_confogure_data = re.sub("<daysToKeep>-?\d+</daysToKeep>", "<daysToKeep>" + daysToKeep + "</daysToKeep>", job_confogure_data) job_confogure_data = re.sub("<numToKeep>-?\d+</numToKeep>", "<numToKeep>" + numToKeep + "</numToKeep>", job_confogure_data) print(job_confogure_data) jenkins.reconfig_job(job_name, job_confogure_data) # 修改job configure資訊 time.sleep(3)
因為jenkins的特性是:如果構建記錄的儲存幾天 沒有配置,那麼值就是-1,具體可以透過jenkins job的config.xml檢視:
http://xxx.com/jenkins/job/【jobName】/config.xml
所以需要用到一些正規表示式:
<daysToKeep>-?\d+</daysToKeep>
解釋:
?:表示?前面的字元可以出現0到1次
-?\d+ :表示可以是負數,也可以為負數
\d+: 這樣 就只能匹配到正數
