新增配置

以“丢弃旧的构建”配置选项为例，先在web页面手动配置一下相关配置项

使用python-jenkins获取配置信息如下

在web页面删掉配置选项，重新获取配置信息

分析python-jenkins两次获取的配置信息，通过对比发现此次配置添加会在<properties/>标签下面添加以下标签内容：

实现思路：

先获取jobs配置信息，config信息的格式是xml类型的

将获取到的config信息保存到xml文件中

使用xml.etree.ElementTree模块对xml文件进行修改

读取修改后的xml文件信息，使用此信息重新配置jobs

批量添加的代码如下，这里配置的范围是2019文件夹2019-1视图下所有jobs：

运行方式：

[root@CSDN /home/Sudley/python-jenkins]#python3 add_config_to_jobs.py ‘username’ ‘passwd’

配置修改

配置的修改和配置添加实现思路类似，比如将原来的“保持构建的最大个数”这一项由3改成30

上述新增配置添加成功后web页面下jobs的配置如下：

此次的代码在新增配置代码的基础下进行适当的修改，修改了if判断条件以及将add_tag2xml()替换为modify_xml()，详细脚本如下

#!/usr/bin/env python# -*- coding:utf-8 -*-# author: Sudley# ctime: 2020/02/09import sysimport jenkinsimport xml.etree.ElementTree as ETdef add_config_to_jobs(username,password):    #此处的server用来获取信息，部分修改操作无法在视图URL下面执行    server = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/job/2019/view/2019-1/',username, password)    view_info = server.get_info()    fail_count = 0    #依次获取对应视图里面的jobs名称及配置信息    for num in range(0,len(view_info['jobs'])):        job_name = view_info['jobs'][num]['name']        print(job_name)        #print('aaaaaaaaa')        jobs_config = server.get_job_config(job_name)        #只有numToKeep的配置是3时菜进行修改        if '
   
    3
   ' not in jobs_config:            print('numToKeep is not equal 3')            continue        #将配置写入xml文件中        tmp_xml = '/tmp/job_config.xml'        with open(tmp_xml,'w') as f:            f.write(jobs_config)            f.write('\n')        try:            #配置xml文件，添加对应的标签            modify_xml(tmp_xml)            with open(tmp_xml,'r') as f:                jobs_config_new = f.read()            #此处的server用于修改配置，配置的名称在上面定义好            server_1 = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/',username, password)            job_name_new = '2019/' + job_name            #print(job_name_new)            #print(jobs_config_new)            #修改job配置前需要先对其执行disable操作            #print('bbbbbbbbbbb')            server_1.disable_job(job_name_new)            server_1 = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/',username, password)            server_1.reconfig_job(job_name_new,jobs_config_new)            #print('cccccccccccccccc')            server_1.enable_job(job_name_new)        except Exception as e:            #print(e)            #将配置失败的job名称保存到/tmp/config_failed.list列表中            fail_list = '/tmp/config_failed.list'            if fail_count == 0:                with open(fail_list,'w') as f:                    f.write(job_name + '\n')            else:                with open(fail_list,'a') as f:                    f.write(job_name + '\n')            fail_count = fail_count + 1def modify_xml(tmp_xml):    #print(tmp_xml)    #使用ET模块解析xml文件    tree = ET.parse(tmp_xml)    root = tree.getroot()    #修改numToKeep标签文本    #方式一：    for numToKeep in root.iter('numToKeep'):        numToKeep.text = '30'    #方式二：    #root[3][0][0][1].text = '30'    tree.write(tmp_xml)if __name__ == '__main__' :    username = sys.argv[1]    password = sys.argv[2]    add_config_to_jobs(username,password)

配置后的效果

配置删除

删除上面添加的配置，即需要删除xml文件中properties标签下的jenkins.model.BuildDiscarderProperty标签，代码在配置修改的基础上面修改modify_xml()

详细代码如下：

#!/usr/bin/env python# -*- coding:utf-8 -*-# author: Sudley# ctime: 2020/02/09import sysimport jenkinsimport xml.etree.ElementTree as ETdef add_config_to_jobs(username,password):    #此处的server用来获取信息，部分修改操作无法在视图URL下面执行    server = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/job/2019/view/2019-1/',username, password)    view_info = server.get_info()    fail_count = 0    #依次获取对应视图里面的jobs名称及配置信息    for num in range(0,len(view_info['jobs'])):        job_name = view_info['jobs'][num]['name']        print(job_name)        jobs_config = server.get_job_config(job_name)        #只有numToKeep的配置是3时菜进行修改        if 'jenkins.model.BuildDiscarderProperty' not in jobs_config:            print('jenkins.model.BuildDiscarderProperty not configured')            continue        #将配置写入xml文件中        tmp_xml = '/tmp/job_config.xml'        with open(tmp_xml,'w') as f:            f.write(jobs_config)            f.write('\n')        try:            #配置xml文件，添加对应的标签            modify_xml(tmp_xml)            with open(tmp_xml,'r') as f:                jobs_config_new = f.read()            #此处的server用于修改配置，配置的名称在上面定义好            server_1 = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/',username, password)            job_name_new = '2019/' + job_name            #修改job配置前需要先对其执行disable操作            server_1.disable_job(job_name_new)            server_1 = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/',username, password)            server_1.reconfig_job(job_name_new,jobs_config_new)            server_1.enable_job(job_name_new)        except Exception as e:            #print(e)            #将配置失败的job名称保存到/tmp/config_failed.list列表中            fail_list = '/tmp/config_failed.list'            if fail_count == 0:                with open(fail_list,'w') as f:                    f.write(job_name + '\n')            else:                with open(fail_list,'a') as f:                    f.write(job_name + '\n')            fail_count = fail_count + 1def modify_xml(tmp_xml):    #print(tmp_xml)    #使用ET模块解析xml文件    tree = ET.parse(tmp_xml)    root = tree.getroot()    #删除所有properties标签下的jenkins.model.BuildDiscarderProperty标签    for properties in root.findall('properties'):        for BuildDiscarderProperty in properties.findall('jenkins.model.BuildDiscarderProperty'):            properties.remove(BuildDiscarderProperty)    tree.write(tmp_xml)if __name__ == '__main__' :    username = sys.argv[1]    password = sys.argv[2]    add_config_to_jobs(username,password)

主要用到的python模块为jenkins和xml.etree.ElementTre
