Create Node Evaluation

This endpoint creates a new evaluation for the given node. This can be used to force a run of the scheduling logic.

Method	Path	Produces
`POST`	`/v1/node/:node_id/evaluate`	`application/json`

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

Blocking Queries	ACL Required
`NO`	`node:write`

Parameters

:node_id (string: <required>)- Specifies the UUID of the node. This must be the full UUID, not the short 8-character one. This is specified as part of the path.

Sample Request

$ curl \
    http://localhost:4646/v1/node/fb2170a8-257d-3c64-b14d-bc06cc94e34c/evaluate

Sample Response

      "RPCMajorVersion": 1,
      "RPCMinorVersion": 1
    }
  ]
}

Drain Node

This endpoint toggles the drain mode of the node. When draining is enabled, no further allocations will be assigned to this node, and existing allocations will be migrated to new nodes. See the Workload Migration Guide for suggested usage.

Method	Path	Produces
`POST`	`/v1/node/:node_id/drain`	`application/json`

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

Blocking Queries	ACL Required
`NO`	`node:write`

Parameters

:node_id (string: <required>)- Specifies the UUID of the node. This must be the full UUID, not the short 8-character one. This is specified as part of the path.
DrainSpec (object: <optional>) - Specifies if drain mode should be enabled. A missing or null value disables an existing drain.
- Deadline (int: <required>) - Specifies how long to wait in nanoseconds for allocations to finish migrating before they are force stopped. This is also how long batch jobs are given to complete before being migrated.
- IgnoreSystemJobs (bool: false) - Specifies whether or not to stop system jobs as part of a drain. By default system jobs will be stopped after all other allocations have migrated or the deadline is reached. Setting this to true means system jobs are always left running.
MarkEligible (bool: false) - Specifies whether to mark a node as eligible for scheduling again when disabling a drain.

Sample Payload

{
    "DrainSpec": {
         "Deadline": "3600000000000",
         "IgnoreSystemJobs": true
    }
}

Sample Request

$ curl \
    -XPOST \
    --data @drain.json \
    http://localhost:4646/v1/node/fb2170a8-257d-3c64-b14d-bc06cc94e34c/drain

Sample Response

{
  "EvalCreateIndex": 0,
  "EvalIDs": null,
  "Index": 3742,
  "NodeModifyIndex": 3742
}

Purge Node

This endpoint purges a node from the system. Nodes can still join the cluster if they are alive.

Method	Path	Produces
`POST`	`/v1/node/:node_id/purge`	`application/json`

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

Blocking Queries	ACL Required
`NO`	`node:write`

Parameters

:node_id (string: <required>)- Specifies the UUID of the node. This must be the full UUID, not the short 8-character one. This is specified as part of the path.

Sample Request

$ curl \
    -XPOST http://localhost:4646/v1/node/f7476465-4d6e-c0de-26d0-e383c49be941/purge

Toggle Node Eligibility

This endpoint toggles the scheduling eligibility of the node.

Method	Path	Produces
`POST`	`/v1/node/:node_id/eligibility`	`application/json`

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

Blocking Queries	ACL Required
`NO`	`node:write`

Parameters

:node_id (string: <required>)- Specifies the UUID of the node. This must be the full UUID, not the short 8-character one. This is specified as part of the path.

Field Reference

Events - A list of the last 10 node events for this node. A node event is a high level concept of noteworthy events for a node.

Each node event has the following fields:
- Message - The specific message for the event, detailing what occurred.
- Subsystem - The subsystem where the node event took place. Subsysystems include:
  - Drain - The Nomad server draining subsystem.
  - Driver - The Nomad client driver subsystem.
  - Heartbeat - Either Nomad client or server heartbeating subsystem.
  - Cluster - Nomad server cluster management subsystem.
- Details - Any further details about the event, formatted as a key/value pair.
- Timestamp - Each node event has an ISO 8601 timestamp.
- CreateIndex - The Raft index at which the event was committed.
