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](/api/index.html#blocking-queries) and [required ACLs](/api/index.html#acls). | Blocking Queries | ACL Required | | ---------------- | -------------------------- | | `NO` | `namespace:read-job` | ### Parameters - `:job_id` `(string: )` - Specifies the ID of the job (as specified in the job file during submission). This is specified as part of the path. - `JobID` `(string: )` - Specify the ID of the job in the JSON payload - `EvalOptions` `()` - 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 ```text $ curl \ --request POST \ -d @sample.json \ https://localhost:4646/v1/job/my-job/evaluate ``` ### Sample Response ```json { "EvalID": "d092fdc0-e1fd-2536-67d8-43af8ca798ac", "EvalCreateIndex": 35, "JobModifyIndex": 34, } ``` ## Create Job Plan This endpoint invokes a dry-run of the scheduler for the job. | Method | Path | Produces | | ------- | -------------------------- | -------------------------- | | `POST` | `/v1/job/:job_id/plan` | `application/json` | The table below shows this endpoint's support for [blocking queries](/api/index.html#blocking-queries) and [required ACLs](/api/index.html#acls). | Blocking Queries | ACL Required | | ---------------- | ------------ | | `NO` | `namespace:submit-job`
`namespace:sentinel-override` if `PolicyOverride` set | ### Parameters - `:job_id` `(string: )` - Specifies the ID of the job (as specified in - the job file during submission). This is specified as part of the path. - `Job` `(string: )` - Specifies the JSON definition of the job. - `Diff` `(bool: false)` - Specifies whether the diff structure between the submitted and server side version of the job should be included in the response. - `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 ```json { "Job": "...", "Diff": true, "PolicyOverride": false } ``` ### Sample Request ```text $ curl \ --request POST \ --payload @payload.json \ https://localhost:4646/v1/job/my-job/plan ``` ### Sample Response ```json { "Index": 0, "NextPeriodicLaunch": "0001-01-01T00:00:00Z", "Warnings": "", "Diff": { "Type": "Added", "TaskGroups": [ { "Updates": { "create": 1 }, "Type": "Added", "Tasks": [ { "Type": "Added", "Objects": [ "..." ], "Name": "redis", "Fields": [ { "Type": "Added", "Old": "", "New": "docker", "Name": "Driver", "Annotations": null }, { "Type": "Added", "Old": "", "New": "5000000000", "Name": "KillTimeout", "Annotations": null } ], "Annotations": [ "forces create" ] } ], "Objects": [ "..." ], "Name": "cache", "Fields": [ "..." ] } ], "Objects": [ { "Type": "Added", "Objects": null, "Name": "Datacenters", "Fields": [ "..." ] }, { "Type": "Added", "Objects": null, "Name": "Constraint", "Fields": [ "..." ] }, { "Type": "Added", "Objects": null, "Name": "Update", "Fields": [ "..." ] } ], "ID": "example", "Fields": [ "..." ] }, "CreatedEvals": [ { "ModifyIndex": 0, "CreateIndex": 0, "SnapshotIndex": 0, "AnnotatePlan": false, "EscapedComputedClass": false, "NodeModifyIndex": 0, "NodeID": "", "JobModifyIndex": 0, "JobID": "example", "TriggeredBy": "job-register", "Type": "batch", "Priority": 50, "ID": "312e6a6d-8d01-0daf-9105-14919a66dba3", "Status": "blocked", "StatusDescription": "created to place remaining allocations", "Wait": 0, "NextEval": "", "PreviousEval": "80318ae4-7eda-e570-e59d-bc11df134817", "BlockedEval": "", "FailedTGAllocs": null, "ClassEligibility": { "v1:7968290453076422024": true } } ], "JobModifyIndex": 0, "FailedTGAllocs": { "cache": { "CoalescedFailures": 3, "AllocationTime": 46415, "Scores": null, "NodesEvaluated": 1, "NodesFiltered": 0, "NodesAvailable": { "dc1": 1 }, "ClassFiltered": null, "ConstraintFiltered": null, "NodesExhausted": 1, "ClassExhausted": null, "DimensionExhausted": { "cpu": 1 } } }, "Annotations": { "DesiredTGUpdates": { "cache": { "DestructiveUpdate": 0, "InPlaceUpdate": 0, "Stop": 0, "Migrate": 0, "Place": 11, "Ignore": 0 } } } } ``` #### 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.html#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](/api/index.html#blocking-queries) and [required ACLs](/api/index.html#acls). | Blocking Queries | ACL Required | | ---------------- | ---------------------- | | `NO` | `namespace:submit-job` | ### Parameters - `:job_id` `(string: )` - Specifies the ID of the job (as specified in the job file during submission).
