The freezer scheduler is to be executed
as daemon process on the client machines
It has the following responsibilities:
* when using the api:
- register -if necessary- as a client in the api
- download the list of jobs from the api
- schedule the jobs for execution
- launch the freezer client at the scheduled time
- collect metadata and exit codes and upload them to the api
- periodically poll the api for new/updated jobs
- if a job is part of a session (a coordinated group of jobs)
it updates the session status when job starts/stops
* when not using the api
- load jobs configurations from files
- schedule the jobs for execution
- launch the freezer client at the scheduled time
The freezer scheduler can also be used to manage jobs
and sessions using the following positional parameters:
job-list
job-get
job-create
job-delete
job-start
job-stop
session-list
session-get
session-create
session-delete
session-list-job
session-add-job
session-remove-job
or to register the client in the api using the positional parameter:
register
