docker +node 部署vue项目的心路历程
最近自己做了个小项目，试着使用docker来进行发布，而其中用到了node做跨越代理，就是为了解决这个问题至少多花费了我一天时间，不说了直接进入主题吧
step 1 部署环境
- 1 安装 centos 这个是首要的 centos 7
- 2 安装docker docker安装配置教程
step 2 vue项目根目录添加 node所需的 server.js
目录机构如下
prod.server.js 内容如下
var express = require('express');
var config = require('./config/index');
var port = process.env.PORT || config.build.port;
var app = express();
var router = express.Router();
const axios = require('axios')
axios.interceptors.request.use((config) => {
return config;
}, (error) => {
return Promise.reject(error);
});
axios.interceptors.response.use((response) => {
return response;
}, (error) => {
return Promise.reject(error);
});
router.get('/', function (req, res, next) {
req.url = '/index.html';
next();
});
app.use(router);
var apiRoutes = express.Router();
app.use('/api', apiRoutes);
app.get('/api/getDiscList', (req, res) => {
var url = 'https://c.y.qq.com/splcloud/fcgi-bin/fcg_get_diss_by_tag.fcg'
axios.get(url, {
headers: {
referer: 'https://c.y.qq.com/',
host: 'c.y.qq.com'
},
params: req.query
}).then((response) => {
res.json(response.data)
}).catch((e) => {
console.log('错误日志')
console.log(e)
})
}),
app.get('/api/getMusic', (req, res) => {
var url = 'https://c.y.qq.com/base/fcgi-bin/fcg_music_express_mobile3.fcg'
axios.get(url, {
headers: {
referer: 'https://c.y.qq.com/',
host: 'c.y.qq.com'
},
params: req.query
}).then((response) => {
res.json(response.data)
}).catch((e) => {
console.log('错误日志')
console.log(e)
})
}),
app.get('/api/getplaysongvkey', function (req, res) { // 获取vkey
var url = 'https://u.y.qq.com/cgi-bin/musicu.fcg'
axios.get(url, {
headers: {
origin: 'https://y.qq.com',
referer: 'https://y.qq.com/portal/player.html'
},
params: req.query
}).then((response) => {
res.json(response.data)
}).catch((e)=>{
console.log(e)
})
}),
app.get('/api/lyric', (req, res) => {
var url = 'https://c.y.qq.com/lyric/fcgi-bin/fcg_query_lyric_new.fcg'
axios.get(url, {
headers: {
referer: 'https://c.y.qq.com/',
host: 'c.y.qq.com'
},
params: req.query
}).then((response) => {
res.json(response.data)
}).catch((e) => {
console.log('错误日志')
console.log(e)
})
}),
app.get('/api/getSongList', (req, res) => {
var url = 'https://c.y.qq.com/qzone/fcg-bin/fcg_ucc_getcdinfo_byids_cp.fcg'
axios.get(url, {
headers: {
referer: 'https://c.y.qq.com/',
host: 'c.y.qq.com'
},
params: req.query
}).then((response) => {
var ret = response.data
res.json(ret)
}).catch((e) => {
console.log('错误日志')
console.log(e)
})
}),
app.get('/api/suggestSearch', (req, res) => {
var url = 'https://c.y.qq.com/soso/fcgi-bin/search_for_qq_cp'
axios.get(url, {
headers: {
referer: 'https://c.y.qq.com/',
host: 'c.y.qq.com'
},
params: req.query
}).then((response) => {
var ret = response.data
res.json(ret)
}).catch((e) => {
console.log('错误日志')
console.log(e)
})
})
app.use(express.static('./dist'));
module.exports = app.listen(port, function (err) {
if (err) {
console.log(err);
return
}
console.log('Listening at http://localhost:' + port + '\n')
});
与此同时修改package.json 中 node的启动脚本，如下
"private": true,
"scripts": {
"dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
"start": "node prod.server.js",
"lint": "eslint --ext .js,.vue src",
"build": "node build/build.js"
},
将"start": "npm run dev" 改为 "start": "node prod.server.js"
因为直接使用 npm run dev 将无法完成node的代理
会出现调用api接口报错
step 3 执行npm run build 后将dist目录上传到centos
# 执行 ll 查看已上传的文件
[root@VM_0_5_centos vuedev]# ll
total 20
drwxr-xr-x 2 root root 4096 Jul 28 09:01 config
drwxr-xr-x 3 root root 4096 Jul 28 09:01 dist
-rw-r--r-- 1 root root 404 Jul 28 09:02 Dockerfile
-rw-r--r-- 1 root root 2612 Jul 28 09:01 package.json
-rw-r--r-- 1 root root 3253 Jul 28 09:01 prod.server.js
同时在该目录创建一个Dockerfile用于镜像制作，文件内容如下
FROM docker.io/node:8.0-alpine
# Create app directory
WORKDIR /usr/src/vueappdev
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm ci --only=production
# Bundle app source
COPY . .
EXPOSE 9009
CMD [ "npm", "start" ]
Dockerfile文件就很多中配置，还有待研究…
step 4 制作镜像
#cd 到项目目录下
[root@VM_0_5_centos ~]# cd /opt/web_proj/vuedev
# 执行镜像创建 （注意最后的 . 标识使用当前目录下的Dockerfile）
[root@VM_0_5_centos vuedev]# docker build -t vuedev:v1 .
# 执行完上面步骤，现在可以看见你创建的images了
[root@VM_0_5_centos vuedev]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
vuedev v1 ac171f1d6b87 21 hours ago 239 MB
step 5 容器创建
# 创建并运行容器
[root@VM_0_5_centos vuedev]# docker run -p 8191:8009 --name vuedev2 -d vuedev:v1
# 查看容器运行日志
[root@VM_0_5_centos vuedev]# docker logs -f -t --tail 200 vuedev2

Connecting to localhost (localhost)|127.0.0.1|:8190... failed: Connection refused.

【注意】在执行docker run -p 8191:8009 --name vuedev2 -d vuedev:v1
运行容器的时候，端口的指定要小心，不然会被坑；
其中的8191指的是容器向外暴露的端口，而8009这个就要注意了（我当时就没弄明白）
这个并不是Dockerfile中的 EXPOSE 9009
而是 vue中config>index.js 文件里
build:{ port:8009, }
中的 8009
如果你不需要node进行api代理（就是没有修改package.json的script） 如
"scripts": {
"dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js --host 0.0.0.0",
"start": "npm run dev",
"build": "node build/build.js"
},
那么端口就应该是
dev: { port: 18080, }
中的 18080
