Docker Node API

Nodes are instances of the Engine participating in a swarm. Swarm modemust be enabled for these endpoints to work.

Docker Node API is one of 15 APIs that Docker publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Node. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a getting-started guide.

This API exposes 4 operations across 3 paths, and defines 14 schemas. It is described by OpenAPI 2.0, at version 1.54.

Schemas 14

The contract defines 14 schemas that model the data the API accepts and returns. The most detailed are Node (8 properties), NodeDescription (5 properties), NodeSpec (4 properties), TLSInfo (3 properties). Each schema is shown below with its type and property counts.

ObjectVersion

1 property
NodeDescription
object
NodeDescription encapsulates the properties of the Node as reported by the agent.
5 properties
GenericResources
array
User-defined resources can be either Integer resources (e.g, SSD=3) or String resources (e.g, GPU=UUID1).
NodeState
string
NodeState represents the state of a node.
ResourceObject
object
An object describing the resources which can be advertised by a node and requested by a task.
3 properties
EngineDescription
object
EngineDescription provides information about an engine.
3 properties
NodeSpec

Where this information came from

This is an independent, third-party profile of Docker Node API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
