        use Test::Docker::MySQL;
        my $dm_guard = Test::Docker::MySQL->new;

        my $port_1 = $guard->get_port; # get a mysql container port
        my $port_2 = $guard->get_port; # get another mysql container port

        my $dsn_1 = "dbi:mysql:database=mysql;host=127.0.0.1;port=$port_1";
        my $dbh_1 = DBI->connect($dsn , 'root', '', { RaiseError => 1 });
