近日，使用 Serverless 开发了一个应用。其中 CI/CD，是需要考虑的一个问题。这里用到了 Jenkins 和 Docker。并且 Jenkins Pipeline 运行在容器中。

\n

本文将介绍如何使用 Jenkins、Docker 和 Serverless Framework 构建并部署 Serverless 应用。

\n

环境安装

\n

需要安装的软件

\n\n

笔者用的 MacBook，已经事先安装好了 Docker，并且由于从 DockerHub 下载镜像比较慢，为了加快镜像下载速度，设置了使用国内的 Docker 镜像源。

\n

Jenkins 有多种运行方式：

\n\n

笔者这里使用 Docker 运行 Jenkins，因为构建步骤也会运行在 Docker 中，需要将 docker.sock 和 docker 命令挂载到容器中，启动 jenkins 命令如下：

\n
docker run -d -p 8080:8080 --name jenkins -e TZ="Asia/Shanghai" -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock  -v $(which docker):$(which docker)  jenkins/jenkins:lts
\n

注意：由于容器内 Jenkins 服务是由 jenkins 用户启动的，它无法访问 /var/run/docker.sock，因此我们需要更改这个文件的权限。

\n

\n

在 Jenkins 启动后安装需要用到的插件：

\n\n

建议启动后只先安装 Localization: Chinese (Simplified) 插件（该插件由 Jenkins 中文社区维护）。

\n

等安装好 Localization: Chinese (Simplified) 插件，并设置好管理员账号后，再安装其他所需的插件。

\n

为什么要这样做呢？

\n

由于 Jenkins 插件服务器在国外，通常情况下因为网络问题，下载插件会比较慢，也经常会遇到插件下载失败的问题。

\n

为了解决这个痛点，Localization: Chinese (Simplified) 插件提供了使用国内 Jenkins 插件源的功能。

\n

因此，在安装好 Localization: Chinese (Simplified) 插件后，请立即设置使用国内的 Jenkins 插件源，这样之后其他插件的下载将变得快如闪电。

\n

\n

定制构建环境的 docker 镜像

\n

本文使用 Serverless Framework 部署应用到腾讯云。在命令行中运行如下命令进行安装：

\n
npm install -g serverless
\n

serverless 命令行是使用 nodejs 开发的，所以会需要 nodejs 环境。此外，计划部署的应用是用 python 开发的，也会需要到 python 环境。

\n

应用构建部署是在 docker 容器中运行的，所以需要一个同时安装有 nodejs 和 python 的 docker 镜像。

\n

在 GitHub 上找到了 docker-python-nodejs 仓库：https://github.com/nikolaik/docker-python-nodejs。

\n

基于 nikolaik/python-nodejs 镜像构建了新镜像 python-nodejs-serverless，Dockerfile 如下：

\n
FROM nikolaik/python-nodejs:python3.6-nodejs12\nRUN npm config set registry http://registry.npm.taobao.org&&npm install -g serverless
\n

使用 docker build 命令构建镜像：

\n
docker build -t python-nodejs-serverless .
\n

创建 Jenkins Job 构建部署应用

\n

创建一个 Pipeline 类型的 job，名称为：serverless-python-demo-pipeline，并开启参数化构建，增加两个密码参数：TENCENTSECRETID 和 TENCENTSECRETKEY，用于自动登陆腾讯云。

\n

\n

经过不断实践、不断完善，Jenkinsfile 最终内容如下：

\n
pipeline {\n    agent {\n        docker { \n            image 'python-nodejs-serverless' \n            args '-e TZ="Asia/Shanghai"'\n        }\n    }\n    stages {\n        stage('Checkout') {\n            steps {\n                git branch: 'main', url: 'https://github.com/donhui/serverless-python-demo.git'\n            }\n        }\n        stage('EnvSetUp') {\n            steps{\n                wrap([$class: 'MaskPasswordsBuildWrapper']) {\n                    sh 'touch .env'\n                    sh 'echo TENCENT_SECRET_ID=${TENCENT_SECRET_ID} >> .env'\n                    sh 'echo TENCENT_SECRET_KEY=${TENCENT_SECRET_KEY} >> .env'\n                } \n            }\n        }\n        stage('Build') {\n            steps {\n                sh 'pip install -i https://pypi.douban.com/simple/ -r requirments.txt -t ./'\n            }\n        }\n        stage('Deploy') {\n            steps {\n                sh 'serverless deploy'\n            }\n        }\n    }\n    post{\n        always {\n                deleteDir()\n        }\n    }\n}
\n

对于 Jenkinsfile 做如下说明：

\n\n

点击 Build With Parameters—>开始构建，运行 Job：

\n

\n

运行状态截图如下，从下图中可以看到每次构建各个 stage 的耗时：

\n

\n

查看 EnvSetUp stage 的日志，可以看到敏感信息已经被隐藏，保证了信息安全，这要归功于 Mask Passwords 插件：

\n

\n

关于 Mask Passwords 插件的设置，在系统管理—>系统配置中，可以对 Mask Passwords 插件做一些全局设置，如下图所示：

\n

\n

查看 Deploy 日志，可以看到部署成功的信息提示：

\n

\n

打开应用控制台，serverless-python-demo 应用详细信息如下：

\n

\n

总结

\n

本文介绍了如何使用安装 Jenkins 及插件，如何定制构建环境的 Docker 镜像，并展开分析了 Jenkins Pipeline 的核心配置文件：Jenkinsfile。此外，还用到了 Mask Passwords 插件来隐藏敏感信息，保证了信息安全。

\n

本次实践使用 Jenkins + Docker 成功部署了 Serverless 应用，希望对看到这篇文章的读者带来一定的借鉴参考意义。
