我正在學習 Docker，我的目標是docker-compose使用 NGINX 為兩個相同的 Node.js 專案提供服務。我的兩個專案（A 和 B）很簡單hello world：
'use strict';
const express = require('express');
// Constants
const PORT = 8301;
const HOST = '0.0.0.0';
const PATH = '/project-a';
// App
const app = express();
app.get(PATH, (req, res) => {
res.send('<h1>Hello World</h1><p>Project A</p>');
});
app.listen(PORT, HOST);
console.log(`Running on http://${HOST}:${PORT}${PATH}`);
上面是 A，B 具有相同的代碼，但僅更改 port8302和 path /project-b。下面docker-compose：
version: '3.7'
services:
website_a:
image: project_a/node
build:
context: ./projects_a
dockerfile: Dockerfile
container_name: project_a
restart: always
command: sh -c "node server.js"
expose:
- 8301
website_b:
image: project_b/node
build:
context: ./projects_b
dockerfile: Dockerfile
container_name: project_b
restart: always
command: sh -c "node server.js"
expose:
- 8302
nginx:
image: node-project-multisite/nginx
build: nginx
container_name: multisite_project_nginx
ports:
- 80:80
depends_on:
- website_a
- website_b
和nginx的conf：
server {
listen 80;
listen [::]:80;
server_name 127.0.0.1;
# Logging
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
location /project-a {
proxy_pass http://website_a:8301/project-a;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
# max uploadable file size
client_max_body_size 4G;
}
}
server {
listen 80;
listen [::]:80;
server_name 127.0.0.1;
# Logging
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
location /project-b {
proxy_pass http://website_b:8302/project-b;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
# max uploadable file size
client_max_body_size 4G;
}
}
使用docker-compose沒有 NGINX 我可以看到兩者hello world，但使用 NGINX 我只能使用 A，在 B 中有以下訊息：
我哪里寫錯了？
uj5u.com熱心網友回復：
您應該只使用一個“服務器”，因為它們共享 server_name 和埠
server {
listen 80;
listen [::]:80;
server_name 127.0.0.1;
# Logging
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
location /project-a {
proxy_pass http://website_a:8301/project-a;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
# max uploadable file size
client_max_body_size 4G;
}
location /project-b {
proxy_pass http://website_b:8302/project-b;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
# max uploadable file size
client_max_body_size 4G;
}
}
