Finally, when using the Apply operation you cannot define managedFields in the body of the request that you submit.\n\nAn example object with multiple managers could look like this\n\nBounded code example (external data; do not execute automatically):\n```yaml\n---\napiVersion: v1\nkind: ConfigMap\nmetadata:\n  name: test-cm\n  namespace: default\n  labels:\n    test-label: test\n  managedFields:\n  - manager: kubectl\n    operation: Apply\n    time: '2019-03-30T15:00:00.000Z'\n    apiVersion: v1\n    fieldsType: FieldsV1\n    fieldsV1:\n      f:metadata:\n        f:labels:\n          f:test-label: {}\n  - manager: kube-controller-manager\n    operation: Update\n    apiVersion: v1\n    time: '2019-03-30T16:00:00.000Z'\n    fieldsType: FieldsV1\n    fieldsV1:\n      f:data:\n        f:key: {}\ndata:\n  key: new value\n```\n\nIn this example, a second operation was run as an update by the manager called kube-controller-manager. The update request succeeded and changed a value in the data field, which caused that field's management to change to the kube-controller-manager.\n\nIf this update has instead been attempted using Server-Side Apply, the request would have failed due to conflicting ownership.\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
