Jobs HTTP API

The /jobs endpoints are used to query for and interact with jobs.

List Jobs

This endpoint lists all known jobs in the system registered with Nomad.

Method Path Produces
GET /v1/jobs application/json

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries ACL Required
YES namespace:list-jobs

Parameters

  • prefix (string: "") - Specifies a string to filter jobs on based on an index prefix. This is specified as a querystring parameter.

Sample Request

$ curl \
    https://nomad.rocks/v1/jobs

$ curl \
    https://nomad.rocks/v1/jobs?prefix=team

Sample Response

[
  {
    "ID": "example",
    "ParentID": "",
    "Name": "example",
    "Type": "service",
    "Priority": 50,
    "Status": "pending",
    "StatusDescription": "",
    "JobSummary": {
      "JobID": "example",
      "Summary": {
        "cache": {
          "Queued": 1,
          "Complete": 1,
          "Failed": 0,
          "Running": 0,
          "Starting": 0,
          "Lost": 0
        }
      },
      "Children": {
        "Pending": 0,
        "Running": 0,
        "Dead": 0
      },
      "CreateIndex": 52,
      "ModifyIndex": 96
    },
    "CreateIndex": 52,
    "ModifyIndex": 93,
    "JobModifyIndex": 52
  }
]

Create Job

This endpoint creates (aka "registers") a new job in the system.

Method Path Produces
POST /v1/jobs application/json

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries ACL Required
NO namespace:submit-job
namespace:sentinel-override if PolicyOverride set

Parameters

  • Job (Job: <required>) - Specifies the JSON definition of the job.

  • EnforceIndex (bool: false) - If set, the job will only be registered if the passed JobModifyIndex matches the current job's index. If the index is zero, the register only occurs if the job is new. This paradigm allows check-and-set style job updating.

  • JobModifyIndex (int: 0) - Specifies the JobModifyIndex to enforce the current job is at.

  • PolicyOverride (bool: false) - If set, any soft mandatory Sentinel policies will be overridden. This allows a job to be registered when it would be denied by policy.

  • Job (Job: <required>) - Specifies the JSON definition of the job.

  • EnforceIndex (bool: false) - If set, the job will only be registered if the passed JobModifyIndex matches the current job's index. If the index is zero, the register only occurs if the job is new. This paradigm allows check-and-set style job updating.

Field Reference

  • Diff - A diff structure between the submitted job and the server side version. The top-level object is a Job Diff which contains Task Group Diffs, which in turn contain Task Diffs. Each of these objects then has Object and Field Diff structures embedded.

  • NextPeriodicLaunch - If the job being planned is periodic, this field will include the next launch time for the job.

  • CreatedEvals - A set of evaluations that were created as a result of the dry-run. These evaluations can signify a follow-up rolling update evaluation or a blocked evaluation.

  • JobModifyIndex - The JobModifyIndex of the server side version of this job.

  • FailedTGAllocs - A set of metrics to understand any allocation failures that occurred for the Task Group.

  • Annotations - Annotations include the DesiredTGUpdates, which tracks what

  • the scheduler would do given enough resources for each Task Group.

Force New Periodic Instance

This endpoint forces a new instance of the periodic job. A new instance will be created even if it violates the job's prohibit_overlap settings. As such, this should be only used to immediately run a periodic job.

Method Path Produces
POST /v1/job/:job_id/periodic/force application/json

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries ACL Required
NO none

Parameters

  • :job_id (string: <required>) - Specifies the ID of the job (as specified in the job file during submission). This is specified as part of the path.

Sample Request

$ curl \
    --request POST \
    https://nomad.rocks/v1/job/my-job/periodic/force

Sample Response

{
  "EvalCreateIndex": 7,
  "EvalID": "57983ddd-7fcf-3e3a-fd24-f699ccfb36f4"
}

Stop a Job

This endpoint deregisters a job, and stops all allocations part of it.

Method Path Produces
DELETE /v1/job/:job_id application/json

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries ACL Required
NO namespace:submit-job

Parameters

  • :job_id (string: <required>) - Specifies the ID of the job (as specified in the job file during submission). This is specified as part of the path.

  • Purge (bool: false) - Specifies that the job should stopped and purged immediately. This means the job will not be queryable after being stopped. If not set, the job will be purged by the garbage collector.

Sample Request

$ curl \
    --request DELETE \
    https://nomad.rocks/v1/job/my-job?purge=true

Sample Response

{
  "EvalID": "d092fdc0-e1fd-2536-67d8-43af8ca798ac",
  "EvalCreateIndex": 35,
  "JobModifyIndex": 34,
