无法使用自定义配置挂载 Nginx 容器

Question

我正在尝试通过与卷共享的配置文件来安装 Nginx 容器docker-compose.yml。

这里有docker-compose.yml

version: '3.7'

services:
  db:
    image: mariadb
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: lamp

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    depends_on:
      - db
    restart: always
    ports:
      - 8080:80

  nginx:
    image: nginx
    depends_on:
      - db
    ports:
      - 8000:80
    volumes:
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf
      # - ./log:/var/log/nginx
      # - ./code:/usr/share/nginx/html

  php:
    image: phpdockerio/php73-fpm
    depends_on:
      - db

这nginx.conf

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

还有default.conf

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # 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;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

问题是，当我运行时docker-compose up，我收到这些错误

我已经看到类似问题的一些答案，说我应该更改- ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf为- ./docker/nginx/nginx.conf:/etc/nginx/这对我来说没有意义（而且也不起作用）。

有人知道出了什么问题吗？

Answer 1

从链接的错误来看，路径之一似乎./docker/nginx/nginx.conf, ./docker/nginx/default.conf是目录而不是文件。

我建议您不要将配置文件添加为卷。使用 Nginx 的自定义 docker 映像以及其中的配置。您需要更改 docker-compose 文件并为 Nginx 提供 docker 文件，如下所示

Dockerfile

From nginx:latest

COPY ./docker/nginx/default.conf /etc/nginx/conf.d/default.conf
COPY ./docker/nginx/nginx.conf /etc/nginx/nginx.conf

  nginx:

      - db
    ports:
