» Fail Deployment

This endpoint is used to mark a deployment as failed. 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. This endpoint only triggers a rollback if the most recent stable version of the job has a different specification than the job being reverted.

Method Path Produces
POST /v1/deployment/fail/:deployment_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

  • :deployment_id (string: <required>)- 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 Deployment

This endpoint is used to pause or unpause a 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 and required ACLs.

Blocking Queries ACL Required
NO namespace:submit-job

» Parameters

» 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 and required ACLs.

Blocking Queries ACL Required
NO namespace:submit-job

» Parameters

  • :deployment_id (string: <required>)- 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 and JSON payload.

  • All (bool: false) - Specifies whether all task groups should be promoted.

  • Groups (array<string>: nil) - Specifies a particular set of task groups that should be promoted.

» 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. This endpoint only triggers a rollback if the most recent stable version of the job has a different specification than the job being reverted.

Method Path Produces
POST /v1/deployment/allocation-health/:deployment_id application/json

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

Blocking Queries ACL Required

» Parameters

  • :deployment_id (string: <required>)- 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 and the JSON payload.

  • HealthyAllocationIDs (array<string>: nil) - Specifies the set of allocation that should be marked as healthy.

  • UnhealthyAllocationIDs (array<string>: nil) - Specifies the set of allocation that should be marked as unhealthy.
