Question

How to access CloudControl config.free CONFIG_VARS?

Answer 1

As it is not documented well here comes the answer:

if ($credFile = getenv('CRED_FILE')) {
    $credFileContents = file_get_contents($credFile);
    if ($credFileContents !== false) {
        $credData = json_decode($credFileContents, true);
        $value = $credData['CONFIG']['CONFIG_VARS']['MY_VAR'];
    }
}

That means within CRED_FILE the config addon has its corresponding array/secction CONFIG which contains another array/section CONFIG_VARS which then contains your vars.
