kubernetes.deployment.patch ​
Apply a strategic-merge, JSON-merge, or JSON patch to a Deployment
Applies a strategic-merge, JSON-merge, or JSON patch to an existing Deployment. The patch_type argument selects the Content-Type header sent to the Kubernetes API, so all three Kubernetes patch strategies are supported:
strategic(default) — strategic-merge patch;patchmust be a dict.merge— RFC 7396 JSON Merge Patch;patchmust be a dict.json— RFC 6902 JSON Patch;patchmust be a list of operation objects.
The workflow temporarily overrides the Content-Type header on the api_client instance supplied by the connection plugin; the original value is always restored in a finally block.
Inputs:
- connection_uuid: Cloud connection UUID (required)
- namespace: Target namespace (required)
- name: Deployment name (required)
- patch: Patch body — dict for strategic/merge, list for json (required)
- patch_type: One of "strategic" | "merge" | "json"; default "strategic" (optional)
Outputs:
- connection_uuid, namespace, name, patch, patch_type
- generation: Deployment generation after patch (integer or null)
- observed_generation: Last observed generation from status (integer or null)
Plugin required: context.get_plugin("connection").kubernetes_runner_clients(connection_uuid, organization_uuid) must expose apps_v1 (AppsV1Api) with patch_namespaced_deployment and api_client with set_default_header.
