[Bug] 无法通过docker内网连接Miniflux || [Bug] Cannot connect to Miniflux through docker intranet

[Jastmaskerrr]

Describe the Bug

在公网可以正常使用，但reactflux和Miniflux 加入同一个Docker 网络，使用Docker 的内部 DNS 解析，无法连接

Steps to Reproduce

reactflux配置

services:
  reactflux:
    image: electh/reactflux:latest
    container_name: reactflux
    restart: unless-stopped
    networks:
      - backend
      - frontend
    #ports:
    #  - 2000:2000
networks:
  backend:
    external: true
  frontend:
    external: true

miniflux配置

services:
  miniflux:
    image: ${MINIFLUX_IMAGE:-miniflux/miniflux:latest}
    container_name: miniflux
    restart: unless-stopped
    networks:
      - backend
      - frontend
    environment:
      BASE_URL: ${BASE_URL}
      DATABASE_URL: postgres://miniflux:${DB_PASSWORD}@postgres-main:5432/miniflux?sslmode=disable
      RUN_MIGRATIONS: "1"
      CREATE_ADMIN: "1"
networks:
  backend:
    external: true
  frontend:
    external: true

Expected Behavior

希望可以通过内网连接

###Describe the Bug

It can be used normally on the public network, but reactflux and Miniflux are added to the same Docker network, and use Docker's internal DNS resolution, and cannot connect.

Steps to Reproduce

reactflux configuration

services:
  reactflux:
    image: electth/reactflux:latest
    container_name: reactflux
    restart: unless-stopped
    networks:
      - backend
      - frontend
    #ports:
    # - 2000:2000
networks:
  backend:
    external: true
  frontend:
    external: true

Miniflux configuration

services:
  miniflux:
    image: ${MINIFLUX_IMAGE:-miniflux/miniflux:latest}
    container_name: miniflux
    restart: unless-stopped
    networks:
      - backend
      - frontend
    environment:
      BASE_URL: ${BASE_URL}
      DATABASE_URL: postgres://miniflux:${DB_PASSWORD}@postgres-main:5432/miniflux?sslmode=disable
      RUN_MIGRATIONS: "1"
      CREATE_ADMIN: "1"
networks:
  backend:
    external: true
  frontend:
    external: true

Expected Behavior

Hopefully connect via the intranet

问题的根本原因是 ReactFlux 是一个纯前端项目，在浏览器中运行，而浏览器无法访问 Docker 内网地址。
具体问题包括 DNS 解析失败、浏览器无法直接访问 Docker 内网、以及前端代码在浏览器中执行而非在 Docker 容器内执行，导致无法正常访问容器内的服务。

---

The root cause of the problem is that ReactFlux is a pure front-end project that runs in the browser and the browser cannot access the Docker intranet address.
Specific problems include DNS resolution failure, browsers cannot directly access Docker intranet, and front-end code is executed in the browser rather than in the Docker container, resulting in the inability to access services in the container normally.
