Docker WordPress container with custom php.ini file settings – Phpmyadmin

I’m running WordPress (and PHPMyAdmin and MySQL) in a Docker container, and I need to make a change to increase the maximum uploadable file size for PHPMyAdmin

I researched a number of solutions and found a suggestion to create a custom uploads.ini file and then include this file in the docker-compose file.

So I have this:

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:

I have included the uploads.ini file in the volumes for wordpress

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

But sadly after running the docker-compose and opening localhost:8080 to go to PHPMyAdmin I still only have a maximum file upload size of 2m, not the 64m in my custom file

    You can try to rebuild your image, but like this.
    Add this somewhere in your your Dockerfile.
    This way you would be sure its not some kind of permission trouble(which I think it is)

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

    You can pass the upload limit to the phpmyadmin docker container with an ENV variable

    Example

    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"

    According to this answer you need to set absolute path to mount single file. So add a ${PWD} before files to be mounted.

    Your volume part would be like:

    volumes:
  - ${PWD}/uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
