使用Nginx和Docker的Webpack开发服务器:在错误的地址上轮询信息 [英] Webpack devserver with Nginx and Docker: polling info on the wrong address
问题描述
我在 Docker 中有2个容器:
- Node.js + Nginx 侦听端口80(通过 docker-compose 文件)
- Node.js + Webpack devserver which listen on port 3000
- Nginx which listen on port 80 (mapped on host port 8080 through docker-compose file)
Nginx正确地代理了对节点容器的请求,我可以通过 http://localhost:8080 访问节点应用,但由于某些原因,还有其他类型为 http://localhost:3000的轮询请求/sockjs-node/info?t = 1570780621084 失败(net :: ERR_CONNECTION_REFUSED),因为在主机上仅可见端口8080上的Nginx.我认为这些轮询请求应定向到Nginx( http://localhost:8080/sockjs-node/info?t = 1570780621084 ),但我不知道我必须在Webpack devserver配置上进行哪些更改以解决此问题.
Nginx correctly proxy requests to the node container and I can access the node app at http://localhost:8080, but for some reasons there are other polling requests of the type http://localhost:3000/sockjs-node/info?t=1570780621084 that fail (net::ERR_CONNECTION_REFUSED) because on the host only Nginx on port 8080 is visible. I think that these polling requests should be directed to Nginx (http://localhost:8080/sockjs-node/info?t=1570780621084) but I don't know what I have to change on the Webpack devserver configuration to fix that.
这是Web pack devserver的配置:
This is the web pack devserver configuration:
const path = require("path");
const webpack = require("webpack");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const { CleanWebpackPlugin } = require("clean-webpack-plugin");
const {
BUILD_DIR,
} = require("./config/config");
module.exports = {
entry: {
bundle: [
"@babel/polyfill",
"./src/app.js",
]
},
output: {
path: BUILD_DIR,
filename: "[name].[hash].js"
},
devtool: "inline-source-map",
devServer: {
host: "localhost",
port: 3000,
contentBase: BUILD_DIR,
historyApiFallback: false,
hot: true,
inline: true,
watchOptions: {
poll: true
},
disableHostCheck: true,
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
{
test: /\.css$/,
use: ["style-loader", "css-loader"],
},
{
test: /\.scss$/,
use: ["style-loader", "css-loader", "sass-loader"]
}
],
},
plugins: [
new CleanWebpackPlugin(),
new HtmlWebpackPlugin({
template: "src/index.html",
filename: "index.html",
inject: true
}),
]
};
这是Nginx的配置:
This is the Nginx configuration:
upstream reactclient {
server react-client:3000 fail_timeout=20s max_fails=10;
}
server {
listen 80;
location / {
proxy_pass http://reactclient;
}
location /sockjs-node/ {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://reactclient;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
到目前为止,我一直尝试在devserver配置的条目中添加以下内容,但是id无效.
What I've tried so far was to add the following in the entry of the devserver config, but id didn't work.
entry: {
bundle: [
`webpack-dev-server/client?http://localhost:8080`,
"webpack/hot/dev-server",
"@babel/polyfill",
"./src/app.js",
]
},
如何使Webpack devserver在Docker中与Nginx一起正常工作?
How can I make Webpack devserver working correctly with Nginx in Docker?
推荐答案
假设 dev-server
在端口3000上运行,而nginx在端口8080上运行,这对我有用(请参阅
Assuming dev-server
is running on port 3000 and nginx on port 8080, this is what has worked for me (see web-devserver public option):
Nginx default.conf
Nginx default.conf
upstream reactclient {
server react_client:3000 fail_timeout=20s max_fails=100;
}
server {
listen 80;
location / {
proxy_pass http://reactclient;
}
location /sockjs-node/ {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://reactclient;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
