»Deployments HTTP API

The /deployment endpoints are used to query for and interact with deployments.

List Deployments

This endpoint lists all deployments.

Method	Path	Produces
`GET`	`/v1/deployments`	`application/json`

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

Blocking Queries	ACL Required
`YES`	`namespace:read-job`

Parameters

prefix (string: "")- Specifies a string to filter deployments based on an ID prefix. Because the value is decoded to bytes, the prefix must have an even number of hexadecimal characters (0-9a-f) .This is specified as a query string parameter and is used before any filter expression is applied.
namespace (string: "default") - Specifies the target namespace. Specifying * will return all evaluations across all authorized namespaces. This parameter is used before any filter expression is applied.
next_token (string: "") - This endpoint supports paging. The next_token parameter accepts a string which is the ID field of the next expected deployment. This value can be obtained from the X-Nomad-NextToken header from the previous response.
per_page (int: 0) - Specifies a maximum number of deployments to return for this request. If omitted, the response is not paginated. The ID of the last deployment in the response can be used as the last_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.
reverse (bool: false) - Specifies the list of returned deployments should be sorted in the reverse order. By default deployments are returned sorted in chronological order (older deployments first), or in lexicographical order by their ID if the prefix query parameter is used.

Fail Deployment

This endpoint is used to mark a deployment as failed.

Sample Payload

{
  "DeploymentID": "5456bd7a-9fc0-c0dd-6131-cbee77f57577",

}

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
`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 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.

Sample Payload

{
  "DeploymentID": "5456bd7a-9fc0-c0dd-6131-cbee77f57577",
  "HealthyAllocationIDs": [
    "eb13bc8a-7300-56f3-14c0-d4ad115ec3f5",

Unblock Deployment

This endpoint is used to manually mark a blocked multiregion deployment as successful. A blocked deployment is a multiregion deployment within a region that has completed within a region but is waiting on the other federated regions. The endpoint can be used in cases where a failed peer region is unable to communicate its failed deployment status to other regions to force a deployment to complete.

Method	Path	Produces
`POST`	`/v1/deployment/unblock/:deployment_id`	`application/json`

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

Blocking Queries	ACL Required
