Nodes API

Nodes API provides a way to query information about the nodes in the cluster.

Describe Node

Endpoint: GET /api/v1/orchestrator/nodes/:nodeID

Retrieve information about a specific node.

Parameters:

• :nodeID: Identifier of the node to describe. (e.g. QmUDAXvv31WPZ8U9CzuRTMn9iFGiopGE7rHiah1X8a6PkT)

Response:

• Node: Detailed information about the requested node.

Example:

curl 127.0.0.1:1234/api/v1/orchestrator/nodes/QmUDAXvv31WPZ8U9CzuRTMn9iFGiopGE7rHiah1X8a6PkT

List Nodes

Endpoint: GET /api/v1/orchestrator/nodes

Retrieve a list of nodes.

Parameters:

• labels: Use label-based criteria to filter nodes. See Label Filtering for usage details.

• limit: Set the maximum number of jobs to return. Default is set to 10.

• next_token: Utilize this parameter for pagination continuation.

• order_by: Determine the ordering of jobs. Choose between id, type, available_cpu, available_memory, available_disk or available_gpu. (default is id).

• reverse: Opt to reverse the default order of displayed jobs.

Response:

• Nodes: List of matching nodes.

• NextToken (string): Pagination token.

Example:

Find two linux nodes with most available Memory

curl --get  "127.0.0.1:1234/api/v1/orchestrator/nodes?limit=2&order_by=available_memory" --data-urlencode 'labels=Operating-System=linux'
