Describe Job

Endpoint: GET /api/v1/orchestrator/jobs/:jobID

Retrieve the specification and current status of a particular job.

Parameters:

  • :jobID: Identifier of the job to describe. This can be full ID of the job (e.g. j-28c08f7f-6fb0-48ed-912d-a2cb6c3a4f3a) or just the short format (e.g. j-28c08f7f) if it's unique.

Response:

  • Job: Specification for the requested job.
