This is a Play web application that allows jobs to be scheduled through a web interface. A job is simply a command.

Queues must be preconfigured in the the application.conf file. Each queue has a cofigurable number of executors, and a maximum duration for jobs.

Jobs that are queued are files in the queue directory.

When they are running they are are directory the spool directory. If the job failed to start, ended with a non-zero exit code or didn't end within the maximum execution time, it's moved into the failed directory with a file reason that indicates the failure reason.

If a job completed succesfully it is moved into the completed directory.

While a job is in the spool, completed or failed directory, it also has files job, stdout and stderr which contain the job description, standard output and standard error, respectively.

Define queues in application.conf. Create the data directory and make sure it's readable for the app. Run the app and browse to /queues.
