Jobs API reference

Detailed documentation on the jobs API

With the jobs API, you can schedule jobs and tasks in the future.

The HTTP APIs are intended for development and testing only. For production scenarios, the use of the SDKs is strongly recommended as they implement the gRPC APIs providing higher performance and capability than the HTTP APIs.

Schedule a job

Schedule a job with a name.

POST http://localhost:3500/v1.0-alpha1/jobs/<name>

URL parameters

Parameter Description
name Name of the job you’re scheduling
data A JSON serialized value or object.
schedule An optional schedule at which the job is to be run. Details of the format are below.
dueTime An optional time at which the job should be active, or the “one shot” time, if other scheduling type fields are not provided. Accepts a “point in time” string in the format of RFC3339, Go duration string (calculated from creation time), or non-repeating ISO8601.
repeats An optional number of times in which the job should be triggered. If not set, the job runs indefinitely or until expiration.
ttl An optional time to live or expiration of the job. Accepts a “point in time” string in the format of RFC3339, Go duration string (calculated from job creation time), or non-repeating ISO8601.

schedule

schedule accepts both systemd timer-style cron expressions, as well as human readable ‘@’ prefixed period strings, as defined below.

Systemd timer style cron accepts 6 fields:

Example 1

“0 30 * * * *” - every hour on the half hour

Period string expressions:
