This docker image contains a built version the alpha release of magento/baler. This is designed to be used within a CI environment such as circleci.
In addition to baler, the image contains PHP 7.2, and most php extensions you'll need for a typical Magento 2.3.x installation. On top of this we have installed: git, git-crypt, and rsync as us
A full list of what php extensions are installed is available on our base PHP docker image here: playsportsgroup/docker-php.
