Deprecated Functionality: Function mcrypt_module_open() is deprecated with php:7.1-fpm-0

[iandd0824]

Try to install the version 2.1.4 and run into the deprecated exception if I use the php version magento2-php:7.1-fpm-0 in setup container.

There is no deprecated exception with magento2-php:7.0-fpm-0.

docker-compose.yml

setup:
  image: mageinferno/magento2-php:7.1-fpm-0
  command: /usr/local/bin/mage-setup
  links:
    - db
  volumes_from:
    - appdata
  env_file: env/setup.env

Command

$ docker-compose run --rm setup

Not going to monkey-patch Magento 2's shit core code. They can do that.

I merged in a fix that downgrades back to PHP 7.0. Once @magento cares enough to put out a proper fix (and not take months to do it), I'll upgrade the compose back to PHP 7.1.
