Automated Scheduling Feature (API)

Mist.io allows you to store and run scheduled tasks (cronjobs) that can run your scripts and schedule actions on your servers.

There are three types of tasks: interval (running periodically), crontab (with a format that resembles the unix crontab file) and one_off (runs only once).

A scheduled task can also have an activation time, an expiration time and can be disabled and kept for future use. Mist.io provides a REST API for task management. All scheduled task results can be accessed through the Mist.io logs.

Adding a task

Adding a task requires a POST call to /api/v1/schedules. For example, the following task will try to start the machine every 2 minutes:

user@user:/tmp$ curl -H "Authorization: 51fb1fc5554d0861d80843dd2612234365feb8211e9d191a70fde56a340bf742" -X POST -d '{'name':'test','action':'start', 'machines_per_cloud':[["b48a696e84554275a52fbe6278f6df56","i-781daaf3"]],'enabled':true,'expires':'2016-11-10 20:20:00','cronjob_type':'interval','cronjob_entry':JSON.stringify({"every" : 2,"period" : "minutes"})}' https://mist.io/api/v1/schedules

while this example, will run a script every 2 hours:

user@user:/tmp$ curl -H "Authorization: 51fb1fc5554d0861d80843dd2612234365feb8211e9d191a70fde56a340bf742" -X POST -d '{'name':'test','script_id':'875cabc81fa1438b98ef25f099bbdf09', 'machines_per_cloud':[["b48a696e84554275a52fbe6278f6df56","i-781daaf3"]],'enabled':true,'expires':'2016-11-10 20:20:00','cronjob_type':'interval','cronjob_entry':JSON.stringify({"every" : 2,"period" : "hours"})}' https://mist.io/api/v1/schedules

example of crontabs
{"minute" : "30", "hour" : "2", "day_of_week" : "*", "day_of_month" : "*", "month_of_year" : "*"}
other crontab examples: http://docs.celeryproject.org/en/latest/userguide/periodic-tasks.html#crontab-schedules
* one_off: (ex. 'cronjob_entry':'2016-2-28 16:20:00' )

Getting all your tasks

To get a list of all your tasks, you need to send a GET call to / api /v1/schedules. E.g.:

user@user:/tmp$ curl -X GET -H "Authorization: 51fb1fc5554d0861d80843dd2612234365feb8211e9d191a70fde56a340bf742" https://mist.io/api/v1/schedules

Getting a specific task

To get a specific task, you need to send a GET call to / api /v1/schedules/taskId. E.g.:

user@user:/tmp$ curl -X GET -H "Authorization: 51fb1fc5554d0861d80843dd2612234365feb8211e9d191a70fde56a340bf742" https://mist.io/api/v1/schedules/3bb46efc882c4b44b21826e5e98f7c28

Editing a task

To edit the configuration of a task, you need to send a PUT call to / api /v1/schedules/taskId. E.g.:

user@user:/tmp$ curl -H "Authorization: 51fb1fc5554d0861d80843dd2612234365feb8211e9d191a70fde56a340bf742" -X POST -d '{'name':'test','script_id':'875cabc81fa1438b98ef25f099bbdf09', 'machines_per_cloud':[["b48a696e84554275a52fbe6278f6df56","i-781daaf3"]],'enabled':true,'expires':'2016-11-10 20:20:00','cronjob_type':'interval','cronjob_entry':JSON.stringify({"every" : 5,"period" : "hours"})}' https://mist.io/api/v1/schedules/3bb46efc882c4b44b21826e5e98f7c28

Deleting a task

To delete one of your tasks, you need to send a DELETE call to / api /v1/schedules/taskId. E.g.:

user@user:/tmp$ curl -X DELETE -H "Authorization: 51fb1fc5554d0861d80843dd2612234365feb8211e9d191a70fde56a340bf742" https://mist.io/api/v1/schedules/3bb46efc882c4b44b21826e5e98f7c28
