same time, defaults to 21600 (6 hours)Kevin::Command::kevin::worker starts a Minion worker. You can have as many workers as you like.
This is a clone of Minion::Command::minion::worker. The differences are:
-
During immediate stops, the worker stops sending heartbeats, processing remote commands and doing repairs.
-
During graceful stops, the worker stops doing repairs.
-
During a stop, when all jobs have finished, the worker will quit promptly (without sleeping).
-
Allow to disable repairs with
-R 0.
The Kevin::Command::kevin::worker process can be controlled at runtime with the following signals.
Stop gracefully after finishing the current jobs.
Stop immediately without finishing the current jobs.
The Kevin::Command::kevin::worker process can be controlled at runtime through Minion::Command::minion::job, from anywhere in the network, by broadcasting the following remote control commands.
$ ./myapp.pl minion job -b jobs -a '[10]'
$ ./myapp.pl minion job -b jobs -a '[10]' 23Instruct one or more workers to change the number of jobs to perform concurrently. Setting this value to 0 will effectively pause the worker. That means all current jobs will be finished, but no new ones accepted, until the number is increased again.
$ ./myapp.pl minion job -b stop -a '[10025]'
$ ./myapp.pl minion job -b stop -a '[10025]' 23Instruct one or more workers to stop a job that is currently being performed immediately. This command will be ignored by workers that do not have a job matching the id. That means it is safe to broadcast this command to all workers.
Kevin::Command::kevin::worker inherits all attributes from Mojolicious::Command and implements the following new ones.
my $description = $worker->description;
$worker = $worker->description('Foo');Short description of this command, used for the command list.
my $usage = $worker->usage;
$worker = $worker->usage('Foo');Usage information for this command, used for the help screen.
Kevin::Command::kevin::worker inherits all methods from Mojolicious::Command and implements the following new ones.
$worker->run(@ARGV);Run this command.
You can set the KEVIN_WORKER_TRACE environment variable to have some extra diagnostics information printed to $app->log.
