RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php'); if (hash_file('sha384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { include 'composer-setup.php'; } else { echo 'Installer corrupt'; }; unlink('composer-setup.php');";

This always downloads the latest version of composer, but checks against the hash of older version. Maybe this should specify the version to be downloaded?

Actually you can't specify the version of composer-setup.php which should be downloaded, you can only specify the version of composer itself. Maybe this should download composer.phar by hand?

I don't really know anything about Docker, maybe we could use this https://hub.docker.com/_/composer

Damn the checksum thing is quite maddening... I'll try to look for a way to fix the composer version (as the dockerfile is meant for dev env anyway)
