Question

我有一个在我的localhost中运行app.dev域的应用程序。但是，我想要使用不同的端口运行其他应用程序。而不是端口80，它将是app2的域app.dev:2000 2000 /我可能知道我应该对我的docker-compose和nginx做出什么改变？感谢

这是我的docker-compose

version: "2"

volumes: 
  mongostorage:

services:
  app:
    build: ./app
    ports:
      - "3000"
    links:
      - mongo
      - redis
    command: node ./bin/www
  app2:
    build: ./app2
    ports:
      - "2000"
    links:
      - mongo
      - redis
    command: node app.js
  nginx:
    build: ./nginx
    ports:
      - "80:80"
    links:
      - app:app
  mongo:
    image: mongo:latest
    environment:
      - MONGO_DATA_DIR=/data/db
    volumes:
      - mongostorage:/data/db
    ports:
      - "27017:27017"
  redis:
    image: redis
    volumes:
      - ./data/redis/db:/data/db
    ports:
      - "6379:6379"

这是我的ngnix.conf

events {
  worker_connections  1024;
}

http{
    upstream app.dev{
        least_conn;
        server app:3000 weight=10 max_fails=3 fail_timeout=30s;
    }

    server {
        listen 80;
        server_name app.dev;

        location / {
            proxy_pass http://app.dev;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
        }
    }
}

Answer 1

我认为只需按以下方式更改app2的端口即可，因为nginx只能侦听端口80.

app2:
  build: ./app2
  ports:
    - "2000:2000"
  links:
    - mongo
    - redis
  command: node app.js

Answer 2

最简单的方法是在端口2000上公开app2

dbconn.ConnectionString = "Driver={Oracle in OraClient11g_home1};Uid=" & <username> & ";Pwd=" & <password> & ";DBQ=XE_DSN"

dbconn.ConnectionString = "Driver={Microsoft ODBC for Oracle};Uid=" & <username> & ";Pwd=" & <password> & ";Server=XE_DSN"

另一种是通过nginx路由连接，以与第一个应用程序保持一致。

撰写

  app2:
    build: ./app2
    ports:
      - '2000:2000'

Nginx的

  nginx:
    build: ./nginx
    ports:
      - '80:80'
      - '2000:2000'

顺便说一下，在版本2+撰写文件中不需要任何http{ upstream app.dev{ least_conn; server app:3000 weight=10 max_fails=3 fail_timeout=30s; } upstream app2.dev{ least_conn; server app2:2000 weight=10 max_fails=3 fail_timeout=30s; } server { listen 80; server_name app.dev; location / { proxy_pass http://app.dev; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } server { listen 2000; server_name app.dev; location / { proxy_pass http://app2.dev/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } }。您已经可以通过服务名称访问所有服务。
