kubernetes.manifest.validate

Server-side schema validation of a manifest with strict field checking (no mutation)

Server-side schema validation of a Kubernetes manifest with strict field checking (no mutation).

Issues a kubectl apply --dry-run=server --validate=strict equivalent via the raw REST API:

• Content-Type: application/apply-patch+json
• ?dryRun=All&fieldValidation=Strict

The call is non-mutating: the dryRun=All query parameter tells the API server to validate and admit the request through every admission webhook but not to persist any changes.

Inputs:

• connection_uuid: Cloud connection UUID (required)
• manifest: Single-resource manifest dict with at least apiVersion, kind, metadata.name and optionally metadata.namespace (required)

Outputs:

• valid: True if the manifest passed strict validation, False otherwise
• errors: List of {field, message} dicts; empty when valid=True

Plugin required: context.get_plugin("connection").kubernetes_runner_clients(connection_uuid, organization_uuid) must expose api_client (a kubernetes.client.ApiClient instance).
