You have done the right thing to extend the memory_limit (as from docs).

You should be able to see the changed configuration in phpinfo(); in a php file.

However:

  1. Your computer doesn't have enough memory to provide the amount of memory you're trying to use. It seems that you have 2GB total available in your Docker environment?
  2. Most likely your PHP code is doing something wrong and using an infinite amount of memory. Note that your PHP app won't have 2GB available typically on any server, so you're going to have to fix what's actually wrong here.
