前言

本篇主要介绍如何自动化部署前端vue项目

其中，有两种方案：

1. 第一种是利用nginx进行静态资源转发；
2. 第二种方案是利用nodejs进行启动访问；

各个组件版本如下：

1. Docker 最新版本；
2. Jenkins 2.387.3
3. nginx 最新版本
4. nodejs 12.13.0

nginx转发部署

目录结构如下：

nginx.conf

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    # include /etc/nginx/conf.d/*.conf;

    server {
        listen       80;
        server_name  localhost; # 服务器地址或绑定域名

        #charset koi8-r;
        #access_log  /var/log/nginx/host.access.log  main;

        # =========================================================
        # ================== ↓↓↓↓↓↓ start ↓↓↓↓↓↓ ==================
        # =========================================================

        location / {
            root   /usr/share/nginx/html;
            #try_files $uri $uri/ @router;
            index  index.html index.htm;
            try_files $uri $uri/ /index.html; # 解决页面刷新 404 问题
            #proxy_pass http://zhengqingya.gitee.io; # 代理的ip地址和端口号
            #proxy_connect_timeout 600; #代理的连接超时时间（单位：毫秒）
            #proxy_read_timeout 600; #代理的读取资源超时时间（单位：毫秒）
        }

        # =========================================================
        # ================== ↑↑↑↑↑↑ end ↑↑↑↑↑↑ ==================
        # =========================================================

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }

    }
}

Dockerfile

FROM nginx:latest
# docker 传参数据
ARG ACTIVE

# 将dist文件中的内容复制到 `/usr/share/nginx/html/` 这个目录下面
ADD /dist  /usr/share/nginx/html
# 用本地配置文件来替换nginx镜像里的默认配置
ADD nginx/nginx-${ACTIVE}.conf /etc/nginx/nginx.conf

EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]  

如果不想在jenkinsfile中运行npm相关命令，而在dockerfile中运行，Dockerfile如下：

FROM node:12.13.0 as build-stage
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build

FROM nginx:latest AS prod-stage
COPY --from=build-stage /app/dist /usr/share/nginx/html  
EXPOSE 80  
CMD ["nginx", "-g", "daemon off;"]  

JENKINSFILE

pipeline {
    agent any
    environment {
        NAME = 'bst-web'
        PROFILE = 'dev'
        APP = 'xxxx/bst-web:dev'
        APP_PORT = 80
    }

    stages {
        stage('下载代码') {
            steps {
                echo '****************************** download code start... ******************************'
                git branch: 'dev', credentialsId: 'xxxxxxxxxxxxxxxxx', url: 'xxxxxx.git'
            }
        }

        stage('vue环境准备') {
            steps {
                echo '****************************** vue start... ******************************'
                sh "npm install && npm run build"
            }
        }

        stage('构建Docker镜像') {
            steps {
                echo '****************************** delete container and image... ******************************'
                sh 'docker ps -a|grep $NAME|awk \'{print $1}\'|xargs -i docker stop {}|xargs -i docker rm {}'
                sh 'docker images|grep $NAME|grep dev|awk \'{print $3}\'|xargs -i docker rmi {}'

                echo '****************************** build image... ******************************'
                sh 'docker build --build-arg ACTOVE=dev -t $APP .'
            }
        }

        stage('运行容器') {
            steps {
                echo '****************************** run start... ******************************'
                sh 'docker run -d -p $APP_PORT:80 --restart=always --name $NAME $APP'
            }
        }
    }
}

nodeJs部署

Dockerfile

FROM node:12.13.0
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build

EXPOSE 8080  
CMD [ "npm", "run", "serve" ]

Jenkinsfile

pipeline {
    agent any
    environment {
        NAME = 'bst-web'
        PROFILE = 'dev'
        APP = 'xxxx/bst-web:dev'
        APP_PORT = 80
    }

    stages {
        stage('下载代码') {
            steps {
                echo '****************************** download code start... ******************************'
                git branch: 'dev', credentialsId: 'xxxxxxxxxxxxxxxxx', url: 'xxxxxx.git'
            }
        }

        stage('构建Docker镜像') {
            steps {
                echo '****************************** delete container and image... ******************************'
                sh 'docker ps -a|grep $NAME|awk \'{print $1}\'|xargs -i docker stop {}|xargs -i docker rm {}'
                sh 'docker images|grep $NAME|grep dev|awk \'{print $3}\'|xargs -i docker rmi {}'

                echo '****************************** build image... ******************************'
                sh 'docker build --build-arg ACTOVE=dev -t $APP .'
            }
        }

        stage('运行容器') {
            steps {
                echo '****************************** run start... ******************************'
                sh 'docker run -d -p $APP_PORT:80 --restart=always --name $NAME $APP'
            }
        }
    }
}

vue.config.js

module.exports = {
	devServer: {
		// 跳过host检查
   	 	historyApiFallback: true,
	}
}

具体版本不一样，或者添加

module.exports = {
    // 跳过检查host
    devServer: { disableHostCheck: true }
}

如果不添加此处内容的话，访问会报错 Invalid Host header
