ResolveComponentCandidates

Source: src/AWS/GreengrassV2/ResolveComponentCandidates.ts

Runtime binding for greengrass:ResolveComponentCandidates.

Resolves a set of component candidates against a target platform, returning the exact component versions (and their recipes) that satisfy the version requirements — the same dependency-resolution API the Greengrass nucleus calls during a deployment. Provide the implementation with Effect.provide(AWS.GreengrassV2.ResolveComponentCandidatesHttp).

NOTE: per the AWS API reference, this operation must be called through the Greengrass data plane endpoint authenticated with an AWS IoT device certificate. Calls signed with plain IAM credentials (e.g. from a Lambda role) are rejected with a typed AccessDeniedException even when the greengrass:ResolveComponentCandidates permission is granted — use this binding only from device-credentialed contexts.

Reading Components

// init — account-level binding, no resource argument
const resolveComponentCandidates =
  yield* AWS.GreengrassV2.ResolveComponentCandidates();

// runtime
const { resolvedComponentVersions } = yield* resolveComponentCandidates({
  platform: { attributes: { os: "linux", architecture: "amd64" } },
  componentCandidates: [
    { componentName: "com.example.Hello", versionRequirements: { req: ">=1.0.0" } },
  ],
