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 query string parameter.
namespace (string: "default") - Specifies the target namespace. Specifying * would return all jobs across all the authorized namespaces.

Sample Request

$ curl https://localhost:4646/v1/jobs

$ curl https://localhost:4646/v1/jobs?prefix=team

$ curl https://localhost:4646/v1/jobs?namespace=*&prefix=team

Sample Response

[
  {
    "ID": "example",
    "ParentID": "",
    "Name": "example",
    "Type": "service",
    "Priority": 50,
    "Status": "pending",
    "StatusDescription": "",
    "JobSummary": {
      "JobID": "example",
      "Namespace": "default",
      "Summary": {
        "cache": {
          "Queued": 1,

          "Failed": 0,
          "Running": 0,
          "Starting": 0,

    },
    "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.
PreserveCounts (bool: false) - If set, existing task group counts are preserved, over those specified in the new job spec.

Create Job Evaluation

This endpoint creates a new evaluation for the given job. This can be used to force run the scheduling logic if necessary. Since Nomad 0.8.4, this endpoint supports a JSON payload with additional options. Support for calling this end point without a JSON payload will be removed in Nomad 0.9.

Method	Path	Produces
`POST`	`/v1/job/:job_id/evaluate`	`application/json`

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

Blocking Queries	ACL Required
`NO`	`namespace:read-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.
JobID (string: <required>) - Specify the ID of the job in the JSON payload
EvalOptions (<optional>) - Specify additional options to be used during the forced evaluation.
- ForceReschedule (bool: false) - If set, failed allocations of the job are rescheduled immediately. This is useful for operators to force immediate placement even if the failed allocations are past their reschedule limit, or are delayed by several hours because the allocation's reschedule policy has exponential delay.

Sample Payload

{
  "JobID": "my-job",
  "EvalOptions": {
    "ForceReschedule": true
  }
}

Sample Request

$ curl \

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`	`namespace:dispatch-job` or `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.

Sample Request

$ curl \
    --request POST \
    https://localhost:4646/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://localhost:4646/v1/job/my-job?purge=true

Sample Response

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

Read Job Scale Status

This endpoint reads scale information about a job.

Method	Path	Produces
`GET`	`/v1/job/:job_id/scale`	`application/json`

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

Blocking Queries	ACL Required
`YES`	`namespace:read-job-scaling` or `namespace:read-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.

Sample Request

$ curl \
    https://localhost:4646/v1/job/my-job/scale

Sample Response

{
  "JobCreateIndex": 10,
  "JobID": "example",
  "Namespace": "default",
  "JobModifyIndex": 18,
  "JobStopped": false,
  "TaskGroups": {
    "cache": {
      "Desired": 1,
      "Events": null,
      "Healthy": 1,
      "Placed": 1,
      "Running": 0,
      "Unhealthy": 0
    }
  }
}

Scale Task Group

This endpoint performs a scaling action against a job. Currently, this endpoint supports scaling the count for a task group. This will return a 400 error if the job has an active deployment.

Method	Path	Produces
`POST`	`/v1/job/:job_id/scale`	`application/json`

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

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

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.
Count (int: <optional>) - Specifies the new task group count.
Target (json: required) - JSON map containing the target of the scaling operation. Must contain a field Group with the name of the task group that is the target of this scaling action.
Message (string: <optional>) - Description of the scale action, persisted as part of the scaling event. Indicates information or reason for scaling; one of Message or Error must be provided.
Error (string: <optional>) - Description of the scale action, persisted as part of the scaling event. Indicates an error state preventing scaling; one of Message or Error must be provided.
Meta (json: <optional>) - JSON block that is persisted as part of the scaling event.
PolicyOverride (bool: false) - If set, any soft mandatory Sentinel policies will be overridden. This allows a job to be scaled when it would be denied by policy.

Sample Payload

{
    "Count": 5,
    "Meta": {
        "metrics": [
            "cpu",
            "memory"
        ]
    },
    "Message": "metric did not satisfy SLA",
    "Target": {
        "Group": "cache"
    }
}

Sample Request

$ curl \
    --request POST \
    --data @payload.json \
    https://localhost:4646/v1/job/example/scale

Sample Response

This is the same payload as returned by job update. EvalCreateIndex and EvalID will only be present if the scaling operation resulted in the creation of an evaluation.
