[JavaScript知识库]完成vue项目容器化CICD部署

部署介绍

本文主要是围绕前端vue框架的项目，具体怎么容器化持续集成部署，其中持续集成工具采用了Jenkins

部署准备

新建Dockerfile文件

# Deliver the dist folder with Nginx
FROM nginx:stable-alpine
ENV LANG=C.UTF-8
ENV TZ=Asia/Shanghai

COPY dist /usr/share/nginx/html
COPY nginx.conf /etc/nginx/conf.d/default.conf
RUN chown -R nginx:nginx /usr/share/nginx/html

EXPOSE 80
COPY entrypoint.sh /
RUN chmod +x /entrypoint.sh
CMD ["/entrypoint.sh"]

新建执行nginx脚本文件entrypoint.sh

#!/bin/sh

# Replace env vars in JavaScript files
#echo "Replacing env vars in JS"
#for file in /usr/share/nginx/html/js/app.*.js;
#do
#  echo "Processing $file ...";
#
#  # Use the existing JS file as template
#  if [ ! -f $file.tmpl.js ]; then
#    cp $file $file.tmpl.js
#  fi
#
#  envsubst '$VUE_APP_BACKEND_HOST,$VUE_APP_MATOMO_HOST,$VUE_APP_MATOMO_ID' < $file.tmpl.js > $file
#done

echo "Starting Nginx"
nginx -g 'daemon off;'

新建nginx配置文件nginx.conf

gzip on;
gzip_disable "msie6";
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript image/svg+xml;

server {
  listen 80 default_server;
  #listen [::]:80 default_server;

  root /usr/share/nginx/html;

  index index.html;

  location ~ ^/(css|js)/ {
    # These assets include a digest in the filename, so they will never change
    expires max;
  }

  location ~* ^.+\.(html|htm)$ {
    # Very short caching time to ensure changes are immediately recognized
    expires 5m;
  }

  location / {
    try_files $uri $uri/ /index.html;
  }

  location /platform {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header   Cookie $http_cookie;
    proxy_set_header   Host    $host;
    proxy_pass https://baidu.com/;
    client_max_body_size    500m;

  }
}

### 新建制作镜像制品和运行容器的脚本文件
dockerBuild.sh

```powershell
docker images | grep test-web/latest &> /dev/null

if [ $? -ne 0 ]
then
    echo "test-web/latest is not existed,we will docker build it!!!"
    docker build -t test-web/latest .

else
    echo "test-web/latest is existed!!!"
        docker rmi -f test-web/latest
        docker build -t test-web/latest .
fi


docker ps -a| grep test-web &> /dev/null
if [ $? -ne 0 ]
then
    echo "test-web is not up,we will start up it!!!"

   docker run -d -p 80:80   --name test-web test-web/latest

else
        docker rm -f  om-web
        docker run -d -p 80:80  --name test-web test-web/latest
    echo "test-web is up!!!"
fi

Jenkins部署

nodejs插件安装

如下图所示，在插件管理中安装nodejs插件：

安装nodejs

如下图所示安装nodejs：

构建

执行Shell脚本如下：

# 进入Jenkins工作空间下hxkj项目目录
cd /var/jenkins_home/workspace/test-web

# 下面的命令只需要执行一次，后续可以删除
###
# npm切换为淘宝源
npm config set registry http://registry.npm.taobao.org/
# 安装yarn
npm i yarn -g
# yarn切换为淘宝源
yarn config set registry https://registry.npm.taobao.org
###

# 安装项目中的依赖
yarn
# 打包
npm run dev-build

# 把生成的项目打包成压缩包，方便移动到项目部署目录
# 将编译好的静态项目dist,配置文件（nginx.conf ,Dockerfile,dockerBuild.sh,entrypoint.sh） 一起打成压缩包
tar -zcvf test-web.tar.gz   dist/* nginx.conf Dockerfile dockerBuild.sh entrypoint.sh

构建后操作

执行脚本如下：

cd /home/data/test-web/
\echo ">>>当前工作路径："`pwd`
\shopt -s extglob
\echo ">>>删除：(.htaccess|.user.ini|test-web.tar.gz)之外的文件"
\rm -rf !(.htaccess|.user.ini|test-web.tar.gz)
\echo ">>>解压：test-web.tar.gz"
\tar -zxvf test-web.tar.gz -C ./
\echo ">>>移除：test-web.tar.gz"
\rm -rf test-web.tar.gz
 \chmod -R 777 dockerBuild.sh
 \./dockerBuild.sh
\echo ">>>执行成功"
