Docker Nginx代理:如何使用路径而不是主机名将流量路由到其他容器 [英] Docker Nginx Proxy: how to route traffic to different container using path and not hostname

问题描述

让我们说，现在我有不同的应用程序在同一服务器上的不同路径上运行:

lets say that now I have different app running on the same server on different path:

• 10.200.200.210/ app1
• 10.200.200.210/ app2
• 10.200.200.210/ app3

我想使用nginx作为代理在不同的Docker容器上运行每个应用程序.

I want to run each app on a different Docker container using nginx as a proxy.

我尝试了 jwilder/nginx-proxy ，如果我使用其他域名(app1.domain.com，app2.domain.com等)，但是我无法使用域，我需要使用相同的IP.

I tried jwilder/nginx-proxy and works great if I use different domain names (app1.domain.com, app2.domain.com, etc), but I'm not able to use domains, I need to use the same IP.

我也不能使用其他端口，例如:

also I can't use different ports like:

• 10.200.200.210:81/ app1
• 10.200.200.210:82/ app2
• 10.200.200.210:83/ app3

所有端口都必须在端口80上工作.

all must work on port 80.

1. 是否可以通过配置 jwilder/nginx-proxy 来做到这一点?
2. 是否有另一个像 jwilder/nginx-proxy 这样的Docker镜像.
3. 或者您能给我一些提示，让我自己构建一个nginx docker容器吗?

1. Is there a way to configure jwilder/nginx-proxy to do this?
2. Is there another Docker image like jwilder/nginx-proxy that make it.
3. or pls could you give me some hint to build an nginx docker container by myself?

推荐答案

如果有人仍在寻找答案.通过jwilder/nginx-proxy，您可以基于代理范围或按VIRTUAL_HOST使用自定义Nginx配置.

In case if somebody is still looking for the answer. jwilder/nginx-proxy allows you to use custom Nginx configuration either a proxy-wide or per-VIRTUAL_HOST basis.

在这里，如何使用Per-VIRTUAL_HOST位置配置来做到这一点.

Here's how can you do it with Per-VIRTUAL_HOST location configuration.

1. 在您的poject文件夹内创建另一个文件夹-"vhost.d".
2. 使用"vhost.d"文件夹中的自定义nginx配置创建文件"whoami.local".此文件的名称必须与VIRTUAL_HOST相同！

./vhost.d/whoami.local

./vhost.d/whoami.local

location /app1 {
  proxy_pass http://app1:8000;
}

location /app2 {
  proxy_pass http://app2:8000;
}

1. 创建docker-compose.yml文件.

./docker-compose.yml

./docker-compose.yml

version: '3'

services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    ports:
    - "8080:80"
    volumes:
    - /var/run/docker.sock:/tmp/docker.sock:ro
    - /path/to/vhost.d:/etc/nginx/vhost.d:ro

  gateway:
    image: jwilder/whoami
    environment:
    - VIRTUAL_HOST=whoami.local

  app1:
    image: jwilder/whoami

  app2:
    image: jwilder/whoami

1. 运行docker-compose up
2. 检查配置

在bash中运行:

$ curl -H "Host: whoami.local" localhost:8080
I'm 1ae273bce7a4
$ curl -H "Host: whoami.local" localhost:8080/app1
I'm 52b1a7b1992a
$ curl -H "Host: whoami.local" localhost:8080/app2
I'm 4adbd3f9e7a0
$ docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                  NAMES

52b1a7b1992a        jwilder/whoami        "/app/http"              54 seconds ago      Up 53 seconds       8000/tcp               nginxreverseproxy_app1_1
1ae273bce7a4        jwilder/whoami        "/app/http"              54 seconds ago      Up 53 seconds       8000/tcp               nginxreverseproxy_gateway_1

您还可以在/etc/hosts文件中添加"whoami.local"域，然后直接调用该域.

You can also add "whoami.local" domain to /etc/hosts file and make calls to this domain directly.

/etc/hosts

/etc/hosts

...
127.0.0.1   whoami.local
...

结果:

$ curl whoami.local:8080
I'm 52ed6da1e86c
$ curl whoami.local:8080/app1
I'm 4116f51020da
$ curl whoami.local:8080/app2
I'm c4db24012582
