使用Jenkins构建node项目

环境变量

• 系统管理 -> 系统配置 -> 全局属性 -> 环境变量 -> 新增键值对
• DOCKER_JENKINS_WORKSPACE : /var/lib/docker/volumes/soft_jenkins_home/_data/workspace

NodeJS配置

# 下载NodeJS插件
# 调整[系统管理 -> 全局工具配置 -> nodeJS 配置]
# nodejs 14.15.0

Jenkins配置

• 创建一个自由风格的项目
• 使用gitee作为代码源
• 在 [构建环境] 步骤 添加 [Provide Node & npm bin/ folder to PATH]
• 在[构建]步骤中添加[执行 shell]步骤

pwd

# 删除 dist 的所有内容
rm -rf dist

# 安装依赖(非必须)
npm install --registry https://registry.npm.taobao.org
# 构建项目
npm run build:prod

# 删除除 node_modules和dist 以外的所有内容
ls | grep -v 'node_modules\|dist' | xargs  rm -rf

• 在构建步骤中添加[Send files or execute commands over SSH(通过ssh远程执行shell)]步骤

export app_version='1.0'

• Nginx添加代理配置

• 在conf.d目录中添加mall-admin-web-demo.conf文件

server {
    listen      80;
    server_name mall-admin-web-demo.iuin.xyz iuin.xyz;

    access_log /var/log/mall-admin-web-demo_access.log;
    error_log /var/log/mall-admin-web-demo_error.log;

    location / {
        include cors.conf;
        proxy_set_header Host $host;
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://mall-admin-web-demo;
    }

}

# 镜像下载问题，可试这添加--with-registry-auth看看
docker stack up -c $JOB_NAME.yml --with-registry-auth app
