# 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](/api-docs#blocking-queries) and
[required ACLs](/api-docs#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.

### Sample Request

```shell-session
$ curl https://localhost:4646/v1/jobs
```

```shell-session
$ curl https://localhost:4646/v1/jobs?prefix=team
```

### Sample Response

```json
[
  {
    "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](/api-docs#blocking-queries) and
[required ACLs](/api-docs#acls).

| Blocking Queries | ACL Required                                                                      |
| ---------------- | --------------------------------------------------------------------------------- |
| `NO`             | `namespace:submit-job`<br />`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.

| `YES`            | `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.

- `all` `(bool: false)` - Specifies whether the list of allocations should
  include allocations from a previously registered job with the same ID. This is
  possible if the job is deregistered and reregistered.

## Update Existing Job

This endpoint registers a new job or updates an existing job.

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

The table below shows this endpoint's support for
[blocking queries](/api-docs#blocking-queries) and
[required ACLs](/api-docs#acls).

| Blocking Queries | ACL Required                                                                      |
| ---------------- | --------------------------------------------------------------------------------- |
| `NO`             | `namespace:submit-job`<br />`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.

- `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.

### Sample Payload

```javascript
{
  "Job": {
    // ...
  },
  "EnforceIndex": true,
  "JobModifyIndex": 4
}
```

### Sample Request

```shell-session
$ curl \
    --request POST \
    --data @payload.json \

## 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.

| ------ | -------------------------- | ------------------ |
| `POST` | `/v1/job/:job_id/evaluate` | `application/json` |

The table below shows this endpoint's support for
[blocking queries](/api-docs#blocking-queries) and

| 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

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

### Sample Request

#### 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`](/docs/job-specification/periodic#prohibit_overlap)
settings. As such, this should be only used to immediately run a periodic job.
