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.

---|---|
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.next_token
(string: "")
- This endpoint supports paging. Thenext_token
parameter accepts a string which identifies the next expected job. This value can be obtained from theX-Nomad-NextToken
header from the previous response.per_page
(int: 0)
- Specifies a maximum number of jobs to return for this request. If omitted, the response is not paginated. The value of theX-Nomad-NextToken
header of the last response can be used as thenext_token
of the next request to fetch additional pages.filter
(string: "")
- Specifies the expression used to filter the results. Consider using pagination or a query parameter to reduce resource used to serve the request.namespace
(string: "default")
- Specifies the target namespace. Specifying*
would return all jobs across all the authorized namespaces.meta
(bool: false)

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

- Specifies the original HCL/HCL2/JSON definition of the job. This data is useful for reference only, it is not considered for the actual scheduling ofJob
.EnforceIndex
(bool: false)
- If set, the job will only be registered if the passedJobModifyIndex
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.EvalPriority

(int: 0)
- Specifies theJobModifyIndex

(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.
