Docker Compose无法从Ubuntu WSL访问Nginx主机问题排查

问题描述

平台信息 

- 操作系统：Windows 11 Pro
- 系统版本：22H2（22621.674）
- WSL发行版：Ubuntu 22.04.2 LTS
- Docker Desktop版本：4.22.1（118664）
- Docker Engine版本：v24.0.5

通过docker compose -f docker-compose.yml up启动多组服务后，在Ubuntu和Windows主机上通过localhost:EXPOSED_PORT可正常连接，但无法通过Nginx及/etc/hosts配置的独立主机名访问各服务，会触发ERR_CONNECTION_CLOSED错误。

Ubuntu环境下用curl访问Nginx容器内网IP时，返回curl: (52) Empty reply from server，但Docker容器内部可正常访问。已尝试将网络驱动改为host、在ports属性中指定IP，均未解决问题。

问题排查与解决方案

1. WSL与Docker容器内网IP的路由问题

WSL 2的虚拟化网络默认无法直接访问Docker bridge子网的容器IP，导致curl访问Nginx容器IP返回空响应。

  • 解决方法：在WSL的Ubuntu中添加路由规则，将Docker子网流量导向Windows主机网关：
sudo ip route add 10.10.0.0/25 via $(cat /etc/resolv.conf | grep nameserver | awk '{print $2}')

2. Nginx前端服务端口配置错误

docker-compose中前端服务映射的是3000:3000，但Nginx upstream配置写的是10.10.0.7:3001，端口不匹配导致转发失败。

  • 解决方法：修改Nginx配置中的前端upstream：
upstream moonshine2.frontend.local {
    server 10.10.0.7:3000;
}

3. Nginx启动命令的配置文件生成问题

当前Nginx启动命令依赖/etc/nginx/conf.d/moonshine2.local文件生成default.conf，若该文件不存在或envsubst替换失败，会导致Nginx加载空配置。

  • 解决方法：
    1. 检查${VOLUMES_FOLDER}/local_nginx目录下是否存在moonshine2.local文件，确保配置正确挂载。
    2. 进入容器验证default.conf内容：
      docker exec -it moonshine2.nginx.local cat /etc/nginx/conf.d/default.conf
    3. 若无需环境变量替换，直接修改docker-compose中Nginx的command：
      command: nginx -g 'daemon off;'

4. HTTPS服务端口未映射

Nginx中前端服务配置了443端口，但容器未将443端口映射到主机，导致外部无法访问HTTPS服务。

  • 解决方法：在docker-compose的Nginx服务中添加端口映射：
ports:
  - "8081:80"
  - "443:443"
