具有自定义php.ini文件设置的Docker Wordpress容器

Question

我在Docker容器中运行Wordpress（以及PHPMyAdmin和MySQL），我需要进行更改以增加PHPMyAdmin的最大可上传文件大小

我研究了许多解决方案，发现了一个建议，创建一个定制的uploads.ini文件，然后将该文件包含在docker compose文件中。

所以我有这个：

uploads.ini

file_uploads = On
memory_limit = 64M
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 600

docker-compose.yml

version: '3'

services:
  # Database
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress
    networks:
      - wpsite
  # phpmyadmin
  phpmyadmin:
    depends_on:
      - db
    image: phpmyadmin/phpmyadmin
    restart: always
    ports:
      - '8080:80'
    environment:
      PMA_HOST: db
      MYSQL_ROOT_PASSWORD: password 
    networks:
      - wpsite
  # Wordpress
  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - '8000:80'
    restart: always
    volumes:
      - './:/var/www/html'
      - ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
    networks:
      - wpsite
networks:
  wpsite:
volumes:
  db_data:

我已将uploads.ini文件包含在卷中，用于wordpress

volumes:
      - './:/var/www/html'
      - ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini

但是可悲的是，在运行docker-comment并打开localhost:8080转到PHPMyAdmin后，我仍然只有2m的最大文件上传大小，而不是我自定义文件中的64m

Answer 1

您可以通过ENV变量将上传限制传递给phpmyadmin docker容器

实例

phpmyadmin:
image: phpmyadmin/phpmyadmin
container_name: phpmyadmin
depends_on:
  - mysql
environment:
  - UPLOAD_LIMIT=512M
  - PMA_HOST=mysql
  - PMA_PORT=3306
  - PMA_ARBITRARY=1
ports:
  - "8888:80"

Answer 2

你可以试着重建你的形象，但是像这样。将此添加到Dockerfile中的某个地方。这样你就可以确定这不是某种许可问题（我认为是）

  COPY ./uploads.ini /usr/local/etc/php/conf.d

Answer 3

你想增加最大可上传文件大小的PHPMyAdmin，但uploads.ini你添加你的wordpress容器）

为phpmyadmin容器添加卷，您会很高兴=）

# phpmyadmin
phpmyadmin:
depends_on:
  - db
image: phpmyadmin/phpmyadmin
volumes:
 - ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
restart: always
ports:
  - '8080:80'
environment:
  PMA_HOST: db
  MYSQL_ROOT_PASSWORD: password 
networks:
  - wpsite
