Drush Configuration Files

Both of these files, should be placed within a drush folder inside the root directory of the Git repository.

See https://github.com/amazeeio/drupal-setting-files for more examples.

Drush RC File drush/drushrc.php

In order for Drush to understand the URL of he current site, Drush searches for a file with the name drushrc.php. Knowing the URL of the current site ensures that cronjobs or other commands are running with the correct URL.

if (getenv('AMAZEEIO_BASE_URL')) {
$options['uri'] = getenv('AMAZEEIO_BASE_URL');

See https://github.com/amazeeio/drupal-setting-files for more interesting things that can be put into the drushrc.php file.

Drush Aliases File drush/aliases.drushrc.php

In order for Drush to connect to remote sites and perform synchronizations and other commands, it needs a small file that connects Drush to the amazee.io API.

// Don't change anything here, it's magic!
global $aliases_stub;
if (empty($aliases_stub)) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, 'https://drush-alias.amazeeio.cloud/aliases.drushrc.php.stub');
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    $aliases_stub = curl_exec($ch);

This small script will download the current API connection script from our servers and execute it. The script itself will search for an .amazeeio.yml file, extract the sitegroup name from it and query the amazee.io API for the information about the existing sites for this sitegroup.
