如果Jenkins使用的Master-Slave多节点架构，删除Jenkins JOB后，相应JOB的slave节点的workspace不会被删除

google groups上有相关的讨论：https://groups.google.com/forum/#!topic/jenkinsci-users/SiZ3DL-UJ-8

所以需要自行处理，于是用脚本实现该功能

具体思路是：

遍历jenkins节点的workspace，根据路径解析获得jenkins job name
如果该job不存在（通过python jenkinsapi实现），则删除相应的workspace
- 暂不考虑自定义的workspace
需要在jenkins每个节点上进行处理（可以在jenkins上创建job，将job绑定到相应slave上；也可以在相应slave上直接运行脚本）

相关的Python脚本如下：

# -*- coding: utf-8 -*-
import os
import shutil
import logging

from jenkinsapi.jenkins import Jenkins

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__file__)


def get_jenkins_instance():
    jenkins_url = "http://jenkins.example.com"
    jenkins_username = "username"
    jenkins_password = "password"
    return Jenkins(jenkins_url, username=jenkins_username, password=jenkins_password)


def clean_workspace():
    jenkins_instance = get_jenkins_instance()

    jenkins_workspace_path = "/opt/JENKINS_HOME/workspace/"

    for dirpath, dirnames, filenames in os.walk(jenkins_workspace_path):
        if dirpath == jenkins_workspace_path:
            for dirname in dirnames:
                jenkins_job_name = dirname
                # 如果job被删除，则清理相应的workspace
                if not jenkins_instance.has_job(jenkins_job_name):
                    logger.info("removing workspace dir of job:%s" % dirname)
                    shutil.rmtree(os.path.join(dirpath, dirname))


if __name__ == "__main__":
    clean_workspace()
