[6.11.5] Docker Settings detecting another Docker Daemon running in LXC

The DockerSettings.page looks for a running process called dockerd.

<?
// Add the Docker JSON client
require_once "$docroot/plugins/dynamix.docker.manager/include/DockerClient.php";

$DockerClient  = new DockerClient();
$DockerStopped = pgrep('dockerd')===false; 

function strposX($s, $c, $n=1) { 

Not only does it determine if Docker is running on Unraid itself, but it also finds the second Docker daemon running in LXC.

I would suggest checking if the Docker socket is available.

A possible fix would be
 

$DockerStopped =  file_exists("/var/run/docker.sock")===false;
