测试开发笔记

背景

因为我们的electron程序已经开发完成，期望要能开发人员每次上传代码，打了tag就自动build一份deb文件，自动上传到minio，方便运维人员去拿deb文件部署到ubuntu环境上。我们已有的技术栈包含droneCI,minio,python，于是边有了该方案。本文省略了vault,ldap,minio,harbor的安装与配置，这些程序的安装配置在本网站的其他文章里，就不一一贴出来了

架构图

解释：

1.前端开发上传electron代码到git服务端

2.git服务端通过webhook方式通知drone-server产生了。例如本文只测试的是发布tag触发webhook，还有很多种触发方式都可以设置

3.drone-server收到通知后，再在drone-runner所在的k8s集群里启动一个包含nodejs和python的任务容器

4.任务容器通过electron-forge make 命令打包一个deb文件

5.任务容器通过minio提供的python sdk上传deb文件到minio

drone插件编写

要完成上述目标，第一步就是得编写一个drone的插件

我编写该插件使用的是nodejs16版本的debian系统，然后通过提前安装好需要的如下表格里的工具。注意，因为我用的是华为源，2021年12月9日的时候，华为镜像上最新的electron只到16.0.2版本，所以注意指定版本号

介绍：该插件使用nodejs16版本的debian系统，然后通过提前安装好需要的如下工具。注意，因为我用的是华为源，2021年12月9日的时候，华为镜像上最新的electron只到16.0.2版本，所以注意指定版本号

工具名
rpm
python3-pip
python3
fakeroot
electron@v16.0.2
electron-prebuilt-compile
electron-forge
dpkg
minio的python sdk

代码有3个文件main.py Dockerfile ,requirements.txt，下面是详细介绍

main.py

代码功能是先获取环境变量，然后使用git的tag号替换掉package.json里的version字段。执行yarn install，yanr make，通过环境变量找到需要上传的文件，通过pythonde的sdk上传到minio里。详细代码如下

#main.py
import json
import os
import subprocess

from minio import Minio
from minio.error import S3Error

endpoint = "minio.sfere.local"
access_key = "bababa"
secret_key = "bababa"
bucket = "electronjs"
folder_path = "/drone/src/out/make/deb/x64"
suffix = "deb"
tag = "0.0.0"


def find_file_by_suffix(target_dir, target_suffix="deb"):
    find_res = []
    target_suffix_dot = "." + target_suffix
    walk_generator = os.walk(target_dir)
    for root_path, dirs, files in walk_generator:
        if len(files) < 1:
            continue
        for file in files:
            file_name, suffix_name = os.path.splitext(file)
            if suffix_name == target_suffix_dot:
                find_res.append(os.path.join(root_path, file))
    return find_res


def get_environment():
    global endpoint, access_key, secret_key, bucket, suffix, tag

    if "PLUGIN_ENDPOINT" in os.environ:
        endpoint = os.environ["PLUGIN_ENDPOINT"]
    if "PLUGIN_ACCESS_KEY" in os.environ:
        access_key = os.environ["PLUGIN_ACCESS_KEY"]
    if "PLUGIN_SECRET_KEY" in os.environ:
        secret_key = os.environ["PLUGIN_SECRET_KEY"]
    if "PLUGIN_BUCKET" in os.environ:
        bucket = os.environ["PLUGIN_BUCKET"]
    if "PLUGIN_SUFFIX" in os.environ:
        suffix = os.environ["PLUGIN_SUFFIX"]
    if "PLUGIN_TAG" in os.environ:
        tag = os.environ["PLUGIN_TAG"]


def yarn_make():
    with open('./package.json', 'r', encoding='utf8')as fp:
        json_data = json.load(fp)
    json_data['version'] = tag
    with open('./package.json', 'w', encoding='utf8')as fp:
        json.dump(json_data, fp, ensure_ascii=False, indent=2)
    print('package version replace to ' + tag)
    print(subprocess.run("yarn install", shell=True))
    print(subprocess.run("yarn make", shell=True))


def upload_file():
    file_list = find_file_by_suffix(folder_path, suffix)
    # 创建minio连接，这里因为我们是http的，所以secure=False
    client = Minio(
        endpoint=endpoint,
        access_key=access_key,
        secure=False,
        secret_key=secret_key,
    )

    # 检查bucket是否存在，不存在就创建bucket
    found = client.bucket_exists(bucket)
    if not found:
        client.make_bucket(bucket)
    else:
        print("Bucket 'electronjs' already exists")

    # 上传文件到bucket里
    for file in file_list:
        name = os.path.basename(file)
        client.fput_object(
            bucket, name, file,
        )
        print(
            "'" + file + "' is successfully uploaded as "
                         "object '" + name + "' to bucket '" + bucket + "'."
        )


if __name__ == "__main__":
    get_environment()
    yarn_make()
    try:
        upload_file()
    except S3Error as exc:
        print("error occurred.", exc)

Dockerfile

取一个node16版本的debian系统，使用国内源安装我们在之前列出来要用的工具，然后指定程序入口是我们的python程序。编写完后，使用docker build -t drone-electron-minio-plugin:0.1.0 . 做一个镜像上传到私仓里

electron仓库代码

我们的electron仓库里要添加一个.drone.yml文件和对package.json稍微进行一些修改

package.json

.drone.yml

droneCI的流水线文件，使用了我们在上一节里build出来的drone插件镜像
