sudo docker-compose up -d

sudo docker-compose down

Put uploads.ini in ~/wordpress/
The first time you create this container and any time you wipe the volumes, you may need to comment out this line:

# - ~/wordpress/uploads.ini:/usr/local/etc/php/conf.d/uploads.ini

Because the directory won't exist yet.
Then delete the container, move the file to the directory and restart the container.
