⁠Roundcube for dokku

Simple dokku configuration wrapper for the upstream official roundcubemail⁠ image.

This just ensures that the dokku linked container variables are converted to the expected upstream environment variables.

⁠Configuration

All ROUNDCUBEMAIL_<var> env vars are set to $config[strtolower('<var>')].

i.e.

ROUNDCUBEMAIL_TEST=1

will be

$config['test'] => '1';

If the value can be json decoded to an (assoc) array then this will used as the value.

i.e.

ROUNDCUBEMAIL_ARRAY_VAR="[1,2,3]"
ROUNDCUBEMAIL_ASSOC_VAR="{\"key\":\"value\"}"

will be

$config['array_var'] = [1,2,3];
$config['assoc_var'] = ['key' => 'value'];
