This should be done to force the scheduler to stop creating allocations as part of the deployment or to cause a rollback to a previous job version. | Method | Path | Produces | | ------- | ------------------------------------ | -------------------------- | | `POST` | `/v1/deployment/fail/:deployment_id` | `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` | `none` | ### Parameters - `:deployment_id` `(string: )`- Specifies the UUID of the deployment.

This is done to pause a rolling upgrade or resume it. | Method | Path | Produces | | ------- | ------------------------------------- | -------------------------- | | `POST` | `/v1/deployment/pause/:deployment_id` | `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` | `none` | ### Parameters - `:deployment_id` `(string: )`- Specifies the UUID of the deployment. This must be the full UUID, not the short 8-character one. This is specified as part of the path. - `Pause` `(bool: false)` - Specifies whether to pause or resume the deployment. ### Sample Payload ```javascript { "Pause": true } ``` ### Sample Request ```text $ curl \ --request POST \ https://nomad.rocks/v1/deployment/pause/5456bd7a-9fc0-c0dd-6131-cbee77f57577 ``` ### Sample Response ```json { "EvalID": "0d834913-58a0-81ac-6e33-e452d83a0c66", "EvalCreateIndex": 20, "DeploymentModifyIndex": 20, "Index": 20 } ``` ## Promote Deployment This endpoint is used to promote task groups that have canaries for a deployment. This should be done when the placed canaries are healthy and the rolling upgrade of the remaining allocations should begin. | Method | Path | Produces | | ------- | ------------------------------------- | -------------------------- | | `POST` | `/v1/deployment/promote/:deployment_id` | `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` | `none` | ### Parameters - `:deployment_id` `(string: )`- Specifies the UUID of the deployment. This must be the full UUID, not the short 8-character one. This is specified as part of the path. - `All` `(bool: false)` - Specifies whether all task groups should be promoted. - `Groups` `(array: nil)` - Specifies a particular set of task groups that should be promoted. ### Sample Payload ```javascript { "All": true } ``` ```javascript { "Groups": ["web", "api-server"] } ``` ### Sample Request ```text $ curl \ --request POST \ https://nomad.rocks/v1/deployment/promote/5456bd7a-9fc0-c0dd-6131-cbee77f57577 ``` ### Sample Response ```json { "EvalID": "0d834913-58a0-81ac-6e33-e452d83a0c66", "EvalCreateIndex": 20, "DeploymentModifyIndex": 20, "Index": 20 } ``` ## Set Allocation Health in Deployment This endpoint is used to set the health of an allocation that is in the deployment manually. In some use cases, automatic detection of allocation health may not be desired. As such those task groups can be marked with an upgrade policy that uses `health_check = "manual"`. Those allocations must have their health marked manually using this endpoint. Marking an allocation as healthy will allow the rolling upgrade to proceed. Marking it as failed will cause the deployment to fail. | Method | Path | Produces | | ------- | ------------------------------------------------- | -------------------------- | | `POST` | `/v1/deployment/allocation-health/:deployment_id` | `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` | `none` | ### Parameters - `:deployment_id` `(string: )`- Specifies the UUID of the deployment. This must be the full UUID, not the short 8-character one. This is specified as part of the path. - `HealthyAllocationIDs` `(array: nil)` - Specifies the set of allocation that should be marked as healthy. - `UnhealthyAllocationIDs` `(array: nil)` - Specifies the set of allocation that should be marked as unhealthy. ### Sample Payload ```javascript { "HealthyAllocationIDs": [ "eb13bc8a-7300-56f3-14c0-d4ad115ec3f5", "6584dad8-7ae3-360f-3069-0b4309711cc1" ] } ``` ### Sample Request ```text $ curl \ --request POST \ https://nomad.rocks/v1/deployment/allocation-health/5456bd7a-9fc0-c0dd-6131-cbee77f57577 ``` ### Sample Response ```json { "EvalID": "0d834913-58a0-81ac-6e33-e452d83a0c66", "EvalCreateIndex": 20, "DeploymentModifyIndex": 20, "RevertedJobVersion": 1, "Index": 20 } ```
