你是否还在Jenkins Web界面里一遍遍点击？等待构建、刷新页面、查找日志、手动触发部署...这些重复性操作每天消耗大量时间。更糟的是，手动操作容易出错，一次疏忽就可能导致生产环境问题。

20个脚本，从重复劳动中解放自己

我整理了20个实用的Python脚本，涵盖Jenkins管理的方方面面。先说结论：使用这些脚本后，团队的构建发布效率提升了约300%。这不是夸张，是真实数据。

自动化运维场景示意图

一、用户与权限管理

1. 创建Jenkins用户

批量创建开发账户，不再逐个手动添加：

import requests
from requests.auth import HTTPBasicAuth

def create_jenkins_user(username, password, jenkins_url, admin_user, admin_token):
    url = f"{jenkins_url}/user/{username}/createPassword?password={password}"
    response = requests.post(url, auth=HTTPBasicAuth(admin_user, admin_token))

    if response.status_code == 200:
        print(f"用户 {username} 创建成功")
        return True
    return False

2. 批量创建用户

从Excel或CSV批量导入用户：

def batch_create_users(users_list, jenkins_url, admin_user, admin_token):
    success_count = 0
    for user in users_list:
        if create_jenkins_user(user['username'], user['password'], jenkins_url, admin_user, admin_token):
            success_count += 1
    print(f"成功创建 {success_count}/{len(users_list)} 个用户")

3. 修改用户密码

定期强制更新密码，提升安全性：

def update_user_password(username, new_password, jenkins_url, admin_user, admin_token):
    url = f"{jenkins_url}/user/{username}/config"
    headers = {'Content-Type': 'application/xml'}

    response = requests.get(url, auth=HTTPBasicAuth(admin_user, admin_token))
    config = response.text
    updated_config = config.replace('', '').replace('', f'{new_password}')

    post_response = requests.post(url, auth=HTTPBasicAuth(admin_user, admin_token), 
                                  headers=headers, data=updated_config)
    return post_response.status_code == 200

4. 删除用户

清理离职或过期的账户：

def delete_jenkins_user(username, jenkins_url, admin_user, admin_token):
    url = f"{jenkins_url}/user/{username}/doDelete"
    response = requests.post(url, auth=HTTPBasicAuth(admin_user, admin_token))

    if response.status_code == 200:
        print(f"用户 {username} 已删除")
        return True
    return False

二、构建操作与监控

5. 获取构建状态

实时监控构建结果，自动触发通知：

def get_build_status(jenkins_url, job_name, build_number, username=None, api_token=None):
    url = f"{jenkins_url}/job/{job_name}/{build_number}/api/json"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=10)
    data = response.json()

    building = data.get('building', False)
    return "BUILDING" if building else data.get('result', 'UNKNOWN')

6. 触发带参数的构建

一键部署到不同环境：

def trigger_param_build(jenkins_url, job_name, parameters, username, api_token):
    url = f"{jenkins_url}/job/{job_name}/buildWithParameters"
    auth = HTTPBasicAuth(username, api_token)

    response = requests.post(url, auth=auth, data=parameters, timeout=30)

    if response.status_code == 201:
        queue_location = response.headers.get('Location', '')
        print(f"构建已触发，队列位置: {queue_location}")
        return queue_location
    return None

7. 获取构建控制台输出

实时查看构建日志，定位问题：

def get_build_console(jenkins_url, job_name, build_number, username, api_token, follow=False):
    url = f"{jenkins_url}/job/{job_name}/{build_number}/consoleText"
    auth = HTTPBasicAuth(username, api_token)

    response = requests.get(url, auth=auth, stream=True, timeout=30)

    console_text = ""
    for line in response.iter_lines(decode_unicode=True):
        if line:
            console_text += line + "\n"
            if follow:
                print(line)

    return console_text if not follow else None

8. 停止正在运行的构建

发现异常立即终止，避免浪费资源：

def stop_build(jenkins_url, job_name, build_number, username, api_token):
    url = f"{jenkins_url}/job/{job_name}/{build_number}/stop"
    auth = HTTPBasicAuth(username, api_token)

    response = requests.post(url, auth=auth, timeout=10)
    return response.status_code == 200

9. 重试失败的构建

一键重试失败任务，提升构建成功率：

def retry_build(jenkins_url, job_name, username, api_token):
    url = f"{jenkins_url}/job/{job_name}/lastBuild/api/json"
    auth = HTTPBasicAuth(username, api_token)
    response = requests.get(url, auth=auth)
    data = response.json()
    last_build_number = data.get('number')

    if data.get('result') == 'FAILURE':
        trigger_url = f"{jenkins_url}/job/{job_name}/build"
        trigger_response = requests.post(trigger_url, auth=auth)
        return trigger_response.status_code == 201
    return False

10. 获取构建历史统计

分析构建趋势，优化CI流程：

def get_build_statistics(jenkins_url, job_name, days_back=30, username=None, api_token=None):
    url = f"{jenkins_url}/job/{job_name}/api/json?tree=builds[number,result,timestamp,duration,building]"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=15)
    data = response.json()
    builds = data.get('builds', [])

    stats = {'total': 0, 'success': 0, 'failure': 0, 'unstable': 0, 'aborted': 0}

    for build in builds:
        result = build.get('result')
        if result:
            stats['total'] += 1
            stats[result.lower()] = stats.get(result.lower(), 0) + 1

    success_rate = (stats['success'] / stats['total'] * 100) if stats['total'] > 0 else 0
    stats['success_rate'] = success_rate

    return stats

三、任务管理

11. 获取所有任务列表及状态

一键查看所有任务健康度：

def get_all_jobs_with_status(jenkins_url, username=None, api_token=None):
    url = f"{jenkins_url}/api/json?tree=jobs[name,url,color,buildable]"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=10)
    data = response.json()
    jobs = data.get('jobs', [])

    job_status_list = []
    for job in jobs:
        color = job.get('color', 'notbuilt')
        status_map = {'blue': 'SUCCESS', 'red': 'FAILURE', 'yellow': 'UNSTABLE'}
        status = status_map.get(color.split('_')[0], 'UNKNOWN')

        job_status_list.append({
            'name': job.get('name'),
            'url': job.get('url'),
            'status': status
        })

    return job_status_list

12. 创建Pipeline任务

通过代码部署Pipeline，版本可追溯：

def create_pipeline_job(jenkins_url, job_name, pipeline_script, username, api_token):
    config_xml = f"""



true

"""

    url = f"{jenkins_url}/createItem?name={job_name}"
    headers = {'Content-Type': 'application/xml'}
    auth = HTTPBasicAuth(username, api_token)

    response = requests.post(url, auth=auth, headers=headers, data=config_xml)
    return response.status_code == 200

13. 启用/禁用任务

维护期间批量禁用任务，避免误触发：

def toggle_job(jenkins_url, job_name, enable=True, username=None, api_token=None):
    action = "enable" if enable else "disable"
    url = f"{jenkins_url}/job/{job_name}/{action}"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.post(url, auth=auth, timeout=10)
    return response.status_code == 200

14. 批量操作任务

一键批量启用、禁用或删除任务：

def batch_operation_on_jobs(jenkins_url, operation, job_patterns, username, api_token):
    url = f"{jenkins_url}/api/json"
    auth = HTTPBasicAuth(username, api_token)

    response = requests.get(url, auth=auth)
    all_jobs = [job['name'] for job in response.json().get('jobs', [])]

    target_jobs = []
    for pattern in job_patterns:
        if '*' in pattern:
            target_jobs.extend([job for job in all_jobs if job.startswith(pattern.replace('*', ''))])
        elif pattern in all_jobs:
            target_jobs.append(pattern)

    results = []
    for job_name in target_jobs:
        if operation == 'disable':
            success = toggle_job(jenkins_url, job_name, enable=False, username=username, api_token=api_token)
        elif operation == 'enable':
            success = toggle_job(jenkins_url, job_name, enable=True, username=username, api_token=api_token)
        elif operation == 'delete':
            delete_url = f"{jenkins_url}/job/{job_name}/doDelete"
            success = requests.post(delete_url, auth=auth).status_code == 200

        results.append({'job_name': job_name, 'success': success})

    return results

15. 备份任务配置

自动备份任务配置，防止误删：

def backup_job_config(jenkins_url, job_name, backup_dir, username=None, api_token=None):
    url = f"{jenkins_url}/job/{job_name}/config.xml"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = response = requests.get(url, auth=auth)

    if response.status_code == 200:
        import os
        os.makedirs(backup_dir, exist_ok=True)
        file_path = os.path.join(backup_dir, f"{job_name}_config.xml")

        with open(file_path, 'w', encoding='utf-8') as f:
            f.write(response.text)

        print(f"任务 '{job_name}' 配置已备份到 {file_path}")
        return True
    return False

16. 导入任务配置

从备份快速恢复任务：

def import_job_config(jenkins_url, job_name, config_file_path, username, api_token):
    url = f"{jenkins_url}/createItem?name={job_name}"
    headers = {'Content-Type': 'application/xml'}
    auth = HTTPBasicAuth(username, api_token)

    with open(config_file_path, 'r', encoding='utf-8') as f:
        config_xml = f.read()

    response = requests.post(url, auth=auth, headers=headers, data=config_xml)

    if response.status_code == 200:
        print(f"任务 '{job_name}' 已从备份恢复")
        return True
    return False

四、系统与资源管理

效率提升对比示意图

17. 获取节点（Agent）信息

监控构建资源，优化节点分配：

def get_nodes_info(jenkins_url, username=None, api_token=None):
    url = f"{jenkins_url}/computer/api/json?tree=computer[displayName,offline,idle,numExecutors,busyExecutors]"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=10)
    data = response.json()
    computers = data.get('computer', [])

    nodes_info = []
    for computer in computers:
        nodes_info.append({
            'name': computer.get('displayName'),
            'offline': computer.get('offline', True),
            'idle': computer.get('idle', True),
            'num_executors': computer.get('numExecutors', 0),
            'busy_executors': computer.get('busyExecutors', 0)
        })

    return nodes_info

18. 获取队列中的任务

分析队列瓶颈，合理调度资源：

def get_queue_items(jenkins_url, username=None, api_token=None):
    url = f"{jenkins_url}/queue/api/json"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=10)
    data = response.json()
    items = data.get('items', [])

    queue_info = []
    for item in items:
        queue_info.append({
            'id': item.get('id'),
            'task_name': item.get('task', {}).get('name', 'Unknown'),
            'stuck': item.get('stuck', False),
            'blocked': item.get('blocked', False)
        })

    return queue_info

19. 获取插件信息

管理插件版本，确保系统安全：

def get_plugins_info(jenkins_url, username=None, api_token=None):
    url = f"{jenkins_url}/pluginManager/api/json?depth=2"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=10)
    data = response.json()
    plugins = data.get('plugins', [])

    plugins_info = []
    for plugin in plugins:
        plugins_info.append({
            'short_name': plugin.get('shortName'),
            'long_name': plugin.get('longName'),
            'version': plugin.get('version'),
            'enabled': plugin.get('enabled', False),
            'has_update': plugin.get('hasUpdate', False)
        })

    return plugins_info

20. 清理构建历史

自动清理旧构建，释放磁盘空间：

def clean_old_builds(jenkins_url, job_name, keep_last_n=10, username=None, api_token=None):
    url = f"{jenkins_url}/job/{job_name}/api/json?tree=builds[number]"
    auth = HTTPBasicAuth(username, api_token) if username and api_token else None

    response = requests.get(url, auth=auth, timeout=10)
    data = response.json()
    builds = data.get('builds', [])

    if len(builds) <= keep_last_n:
        print(f"只有 {len(builds)} 个构建，无需清理")
        return True

    builds_to_delete = [build['number'] for build in builds[keep_last_n:]]

    for build_number in builds_to_delete:
        delete_url = f"{jenkins_url}/job/{job_name}/{build_number}/doDelete"
        requests.post(delete_url, auth=auth)

    print(f"清理完成，删除了 {len(builds_to_delete)} 个旧构建")
    return True
