| Name | Type | Default | Required |
|---|---|---|---|
| name | string | null | No |
| label_selector | string | null | No |
| delete_pods_with_local_storage | boolean | false | No |
| timeout | integer | 120 | No |

This action does a similar job to kubectl drain --ignore-daemonsets or kubectl drain --delete-local-data --ignore-daemonsets if delete_pods_with_local_storage is set to True. There is no equivalent to the kubectl drain --force flag.
You probably want to call uncordon from in your experiment’s rollbacks.
