无法将 nginx.conf 卷映射到容器中的目录

Question

首先，我只在我的 Linux VPS 上遇到这个问题。我的 Windows 开发机器上不存在此问题。

我的 VPS 运行的是 Ubuntu 23.04

问题

当我尝试从 docker-compose 脚本启动 docker 容器时，Nginx 容器出现错误并吐出以下内容：

root@srv502529:/docker_projects/personal-site-2024# docker-compose up
Creating network "personal-site-2024_default" with the default driver

我认为造成这种情况的常见原因是 nginx.conf 不在指定的位置，但就我而言，它绝对是：

docker-compose 的片段

services:
  nginx:
    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - /nginx.conf:/etc/nginx/nginx.conf
    depends_on:
      - webserver
      - api_proxy_server
      - cms_server

我尝试过的事情

我尝试过使用此体积映射

./nginx:/etc/

。它显然已加载，并且我在控制台中收到一条

done

消息，但随后我收到此错误：

Answer 1

您提供

/nginx.conf

作为要安装的文件的路径，但您的结构建议它应该是

./nginx.conf

或

/docker_projects/personal-site-2024/nginx.conf

（如果首选绝对路径）。
