jenkins+docker+git+etcd实现应用配置文件管理

两台机器:

一台机器安装gitlab: http://www.cnblogs.com/cjsblogs/p/8716932.html

另一台机器安装etcd+docker+jenkins

jenkins-docker: https://www.cnblogs.com/cjsblogs/p/8717602.html

防火墙端口启动;

firewall-cmd --zone=public --add-port=2379/tcp --permanent
firewall-cmd --zone=public --add-port=2380/tcp --permanent
firewall-cmd --reload

　　

安装etcd:

yum install etcd -y
systemctl start etcd

安装setuptools

wget --no-check-certificate https://pypi.python.org/packages/69/56/f0f52281b5175e3d9ca8623dadbc3b684e66350ea9e0006736194b265e99/setuptools-38.2.4.zip#md5=e8e05d4f8162c9341e1089c80f742f64
unzip setuptools-38.2.4.zip
cd setuptools-38.2.4
python setup.py install
cd ..

　　

安装pip

wget --no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz
tar -xvf 1.5.5.tar.gz #解压文件
cd pip-1.5.5/
python setup.py install

　　

安装python  etcd模块:

pip install python-etcd

　　

在git创建dev组,以及dev_etcd项目, 并且制作好的etcd脚本:

git目录如下:

etcdGet.py

#!/usr/bin/env python2.7
# -*- coding:utf-8 -*-
from __future__ import print_function

import etcd
import sys
import os
import re
etcdCli=etcd.Client(host=sys.argv[1],port=2379)
f = open(sys.argv[3],'wb')
f.write(etcdCli.get('%s' % sys.argv[2]).value.encode('utf-8'))
f.close()

　　

etcdPush.py

#!/usr/bin/env python2.7
# -*- coding:utf-8 -*-
from __future__ import print_function
import etcd
import sys
import time
import os
import re
reload (sys)
etcdCli=etcd.Client(host=sys.argv[1],port=2379)
def push(local_dir, top_path='/', with_local_path=False):
    try:
        for root, dirs, files in os.walk(local_dir):
            if '.' not in dirs and '.' not in root:
                for name in files:
                    file = os.path.join(root, name)
                    f = open(file)
                    content = f.read()
                    f.close()
                    if not with_local_path:
                        etcd_path = '/' + top_path.strip('/') + '/' + file[re.match(local_dir, file).end():].strip(
                            '/')
                    else:
                        etcd_path = '/' + top_path.strip('/') + '/' + file.strip('/')
                    print(etcd_path)
                    etcdCli.write(etcd_path, content)
    except Exception as e:
        etcd.EtcdException(e)
push(sys.argv[2],top_path=sys.argv[3])

　　

etcdRead.py

#!/usr/bin/env python
import etcd
import sys
import time
import os
import re
reload (sys)
def getValue(host,port,location):
    etcdCli=etcd.Client(host=host,port=port)
    context=etcdCli.read(location).value
    return context

envValue=getValue(host=sys.argv[1],port=int(sys.argv[2]),location=sys.argv[3])
print(envValue)

　

getRegistryTagList.py

#!/usr/bin/env python2.7
import requests
import json
import sys

def getRegistryTagList():
    registry="http://harbor.xxx.com"
    res=requests.get(registry+"/v2/")
    assert res.status_code == 200

    res=requests.get(registry+"/v2/_catalog?n=1000")
    assert res.status_code == 200

    repositories = res.json().get("repositories",[])

    for repository in repositories:
        res = requests.get(registry + "/v2/{}/tags/list".format(repository))
        tags = res.json().get("tags",None)
        if tags:
            for tag in tags:
                image = format(repository)
                tag = format(tag)
                if len(sys.argv) <2:
                    print (image+":"+tag)
                else:
                    AppTargetName=sys.argv[1]
                    if image.endswith(AppTargetName):
                        print (image+":"+tag)
if __name__ == "__main__":
    getRegistryTagList()　

此处需要修改对应的私有docker仓库地址

healthyCheck.py

#!/usr/bin/env python
import requests,sys,os

def healthyCheck():
  if len(sys.argv) < 2: sys.exit("need 1 argument")
  url = sys.argv[1]
  try:
    code = requests.get(url,timeout=1).status_code
    if code >= 200 and code < 400:
      print "healthy check ok , status_code:%s" % code
    else:
      print "healthy check not ok, status_code:%s" % code
      sys.exit("healthy check not ok")
  except Exception,e:
    print "e"
if __name__ == "__main__":
  healthyCheck()

　　

import.sh

/opt/dev_etcd/etcdPush.py 172.16.5.113 appCfgs /xxx.com/instances

此处建立etcd推送的配置文件服务器以及路径

以上所有的脚本全部完毕

接下来需要在jenkins上创建job结合git的webhooks推送应用配置文件

jenkins创建job:

截图处创建git的webhooks能用到

以上git clone直接提交用户名和密码拉取git代码, 其中我的密码带有@符号, git clone无法识别@符号, 需要将@转义为%40故账号需要特殊处理:

最后在git上创建webhooks

综上全部创建完毕, 在jenkins上点击job立即构建测试吧
