Why `file_get_contents` don't work in Docker? How can I solve this issue?

问题

  1. <?= file_get_contents( get_template_directory_uri() . "/images/scroll_to_explore.svg" ) ?>
  1. version: '3.3'
  3. services:
  4.   db:
  5.     image: mysql:latest
  6.     volumes:
  7.       - ./database.sql:/docker-entrypoint-initdb.d/init.sql # 预先填充数据库
  8.       - db_data:/var/lib/mysql # 在Docker存储中保留数据库数据
  9.     restart: always
  10.     env_file:
  11.       - .env
  12.     environment:
  13.       DOCKER_COMPOSE_YML_LOCATION: ${PWD}
  14.     container_name: wp_db
  15.   phpmyadmin:
  16.     image: phpmyadmin/phpmyadmin
  17.     restart: always
  18.     ports:

  20.     volumes:
  21.       - /sessions
  22.     environment:
  23.       PMA_HOST: db
  24.       MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
  25.       DOCKER_COMPOSE_YML_LOCATION: ${PWD}
  26.       UPLOAD_LIMIT: 300M

  33.     image: wordpress:latest
  34.     ports:
  35.       - "8000:80"
  36.     restart: always
  37.     environment:

  45.       WORDPRESS_DB_NAME: ${MYSQL_DATABASE}
  46.       DOCKER_COMPOSE_YML_LOCATION: ${PWD}
  47.     volumes:
  48.       # 主题、插件和上传
  49.       - ./wp-content:/var/www/html/wp-content
  50.       # 配置
  51.       - .htaccess:/var/www/html/.htaccess
  52.       # PHP配置
  53.       - ./php-extra.ini:/usr/local/etc/php/conf.d/php-extra.ini
  54.     container_name: wp_wordpress
  55. volumes:
  56.   db_data: {}
  1. allow_url_fopen: 1

我尝试了在 php-extra.ini 中添加自定义PHP配置，但没有帮助。

英文:

I need to embed svg from php. And for this I used

  1. <?= file_get_contents( get_template_directory_uri() . "/images/scroll_to_explore.svg" ) ?>

When I served project locally, all were fine. But now project migrated to Docker. And I got next errors everywhere I have same code:

  1. Warning: file_get_contents(http://0.0.0.0:8000/wp-content/themes/my_theme/images/scroll.svg): 
  2. Failed to open stream: Connection refused in /var/www/html/wp-content/themes/my_theme/parts/front/cover.php

This is my docker-compose.yml:

  1. version: '3.3'
  3. services:
  4.   db:
  5.     image: mysql:latest
  6.     volumes:
  7.       - ./database.sql:/docker-entrypoint-initdb.d/init.sql # prepopulate database
  8.       - db_data:/var/lib/mysql # persist database data inside docker storage
  9.     restart: always
  10.     env_file:
  11.       - .env
  12.     environment:
  13.       DOCKER_COMPOSE_YML_LOCATION: ${PWD}
  14.     container_name: wp_db
  15.   phpmyadmin:
  16.     image: phpmyadmin/phpmyadmin
  17.     restart: always
  18.     ports:
  19.       - "8080:80"
  20.     volumes:
  21.       - /sessions
  22.     environment:
  23.       PMA_HOST: db
  24.       MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
  25.       DOCKER_COMPOSE_YML_LOCATION: ${PWD}
  26.       UPLOAD_LIMIT: 300M
  27.     container_name: wp_phpmyadmin
  28.     depends_on:
  29.       - db
  30.   wordpress:
  31.     depends_on:
  32.       - db
  33.     image: wordpress:latest
  34.     ports:
  35.       - "8000:80"
  36.     restart: always
  37.     environment:
  38.       # debug mode
  39.       WORDPRESS_DEBUG: 1
  41.       # docker wp config settings
  42.       WORDPRESS_DB_HOST: db:3306
  43.       WORDPRESS_DB_USER: ${MYSQL_USER}
  44.       WORDPRESS_DB_PASSWORD: ${MYSQL_PASSWORD}
  45.       WORDPRESS_DB_NAME: ${MYSQL_DATABASE}
  46.       DOCKER_COMPOSE_YML_LOCATION: ${PWD}
  47.     volumes:
  48.       # Theme, plugins and uploads
  49.       - ./wp-content:/var/www/html/wp-content
  50.       # Configurations
  51.       - .htaccess:/var/www/html/.htaccess
  52.       # PHP Configuration
  53.       - ./php-extra.ini:/usr/local/etc/php/conf.d/php-extra.ini
  54.     container_name: wp_wordpress
  55. volumes:
  56.   db_data: {}

This is my php-extra.ini:

  1. allow_url_fopen: 1

I tried to add custom php configuration to php-extra.ini but it didn't help

检查你的配置。你真的不应该尝试通过 0.0.0.0 连接... 这是一个特殊的地址，用于配置服务器监听任何接口。

如果你需要的文件在磁盘上，无需通过 HTTP 加载。如果你确实需要通过 HTTP 加载它，请考虑使用 127.0.0.1 或 localhost。

英文:

Check your configuration. You really shouldn't try to connect via 0.0.0.0... it's a special address for configuring the server to listen on any interface.

If this file you need is on disk, there's no need to load via HTTP anyway. If you do need to load it over HTTP, consider 127.0.0.1 or localhost instead.
