Increase File Upload Size in Local WordPress Docker

If you are trying to import settings from existing WordPress site once you start your local WordPress docker container, you will realise the default max upload size is 2mb.

To increase the upload file size, we can specify custom php.ini file (in our case upload.ini) and setup the Docker compose file to copy it within container.

Create file upload.ini in the same folder as docker-compose.yml

$ touch upload.iniCode language: Bash (bash)

Add following in upload.ini to change the upload_max_filesize.

upload.ini

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

Update the docker-compose.yml file and mount the local upload.ini file.

  wordpress:
    depends_on:
      - db
    image: wordpress
    restart: always
    volumes:
      - ./:/var/www/html/wp-content
      - ./upload.ini:/usr/local/etc/php/conf.d/uploads.ini
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
    ports:
      - 80:80
      - 443:443
    networks:
      - wpCode language: YAML (yaml)

Restart the docker container by running docker-compose up -d

Check the max image size under Media > Add New
