kubernetes.deployment.rollback ​
Roll a Deployment back to a previous revision (kubectl rollout undo equivalent)
Rolls a Deployment back to a previous revision by selecting the matching ReplicaSet and strategic-merge-patching the Deployment's pod-template spec.
This is the modern equivalent of kubectl rollout undo — it does NOT use the deprecated /rollback sub-resource removed in Kubernetes 1.16.
Inputs:
- connection_uuid: Cloud connection UUID (required)
- namespace: Target namespace (required)
- name: Deployment name (required)
- revision: Specific revision number to roll back to (optional). When omitted the highest revision that is NOT the current one is selected (i.e., the previous revision).
Outputs:
- connection_uuid, namespace, name (echoed through)
- rolled_back_to_revision: Revision number that was restored
- previous_revision: Revision that was active before the rollback
- generation: New Deployment generation reported by the API server
Plugin required: context.get_plugin("connection").kubernetes_runner_clients(connection_uuid, organization_uuid) must expose apps_v1 (read_namespaced_deployment, list_namespaced_replica_set, patch_namespaced_deployment) and api_client (sanitize_for_serialization).
