It looks like you added ENV var to the PhpAdmin container config only. But to upload file on site, the 'web-server' container is involved instead, right?

So you need to update the php.ini file of the 'web-server' container.

This can be done by mapping custom php.ini file from host to container. Values in this file will override any existing values. Add this lines to your docker-compose.yml, under the web-server:

volumes:
  - ./path/to/the/local/custom-php.ini:/path/to/the/folder/where/php/scans/additional/ini-files/custom-php.ini

Then create ./path/to/the/local/custom-php.ini (path can be any) file and put there this line:

upload_max_filesize = 500M

After this you need to determine /path/to/the/folder/where/php/scans/additional/ini-files/ folder. This can be done by running this command:

docker exec web-server php --ini

In the output you will see all the ini files used by php, and there will should be smth like "Scan for additional .ini files in: {path to folder}". This is the folder where you should map your custom-php.ini file, i.e. you need to replace /path/to/the/folder/where/php/scans/additional/ini-files/ with this path.
