dynamic drush alias files – devinzuczek.com

Alias files are useful. If you have many sites on a remote server, instead of manually adding them to your alias file every time, write some code to automatically generate them.

$domains = explode("\n", trim(shell_exec("ssh user@myserver.example.com 'ls /some/path'")));
// now $domains is a list of directories on your remote server

// set up an alias for each one
foreach ($domains as $domain) {
    $aliases[$domain] = array(
      'root' => "/path/to/$domain/public_html",
      'remote-host' => 'some-server.com',
      // if necessary, URI other than default
      'uri' => $domain,
      'remote-user' => 'user_if_necessary',
    );
}

$domains = explode("\n", trim(shell_exec("ssh user@myserver.example.com 'ls /some/path'")));

// now $domains is a list of directories on your remote server

// set up an alias for each one

foreach ($domains as $domain) {

$aliases[$domain] = array(

'root' => "/path/to/$domain/public_html",

'remote-host' => 'some-server.com',

// if necessary, URI other than default

'uri' => $domain,

'remote-user' => 'user_if_necessary',

);

}

Now whenever a site is configured on your target server, you will automatically have the alias!
