如何使用多個節點應用程序設置 nginx 反向代理

Question

我有兩個 Vue.js 應用程序想要在同一個域上運行（例如， https://localhost:8080/app1和https://localhost:8080/app2 ）。 這兩個應用程序都在單獨的 docker 容器中運行，並且我已經設置了第三個 docker 容器，該容器運行帶有反向代理的 nginx 以便擁有 ssl。

我可以在所需位置訪問應用程序，但缺少一些資源（圖像、字體等）。 我意識到我的 nginx 服務器在https://localhost:8080/my_resource 尋找它們，但我不知道如何將它們轉發到正確的位置（即https://localhost:8080/app1/my_resource ，和 app2 類似）。

我嘗試在 nginx 中使用“try_files”指令，如下所示：

location / {
   try_files $uri $uri/ http://app1:8080 http://app2:8080
}

但它不起作用。

這是我的 nginx 配置文件

server {
  listen 80;
  listen [::]:80;
  server_name localhost;
  return 301 https://$server_name$request_uri;
}

# Change the default configuration to enable ssl
server {
    listen 443 ssl;
    listen [::443] ssl;

    ssl_certificate /etc/nginx/certs/my_app.crt;
    ssl_certificate_key /etc/nginx/certs/my_app.key;

    server_name localhost;
    server_tokens off;

    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;

    location / {
        if ($http_referer = "https://localhost:8080/app1/") {
            proxy_pass http://app1:8080;
            break;
        }
        if ($http_referer = "https://localhost:8080/app2/") {
            proxy_pass http://app2:8080;
            break;
        }
    }


    location /app1/ {
        proxy_pass http://app1:8080/;
    }

    location /app2/ {
        proxy_pass http://app2:8080/;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

這是我的 docker-compose

version: "3.6"
services:
  app1:
    image: "app1"
    expose:
      - "8080"
    command: ["serve", "-s", "/app/app1/dist", "-l", "8080"]

  app2:
    image: "app2"
    expose:
      - "8080"
    command: ["serve", "-s", "/app/app2/dist", "-l", "8080"]

  nginx:
    image: "nginx"
    ports:
      - "8080:443"
    depends_on:
      - "app1"
      - "app2"

感謝您的任何輸入:)

經過大量的反復試驗，我找到了解決方案。 我不認為這是最佳解決方案，但它正在起作用。 這是我的nginx配置：

# Pass any http request to the https service
server {
    listen 80;
    listen [::]:80;
    server_name localhost;
    return 301 https://$server_name$request_uri;
}

# Configure the ssl service
server {
    listen 443 ssl;
    listen [::443] ssl;

    ssl_certificate /etc/nginx/certs/my_app.crt;
    ssl_certificate_key /etc/nginx/certs/my_app.key;

    server_name localhost;
    server_tokens off;

    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;

    location / {
        proxy_intercept_errors on;
        error_page 404 = @second;
        proxy_pass http://app1:80;
    }

    location @second {
        proxy_pass http://app2:80;
    }


    location /app1/ {
        rewrite ^/app1(.*) /$1 break;
        proxy_pass http://app1:80;
    }

    location /app2/ {
        rewrite ^/app2(.*) /$1 break;
        proxy_pass http://app2:80;
    }

    # redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}
