2. Configure the `from.host` in the `source1.yaml` file as the MySQL host address that the Kubernetes cluster can access internally.
1. Edit task configuration file `task.yaml`, which can refer to [Configure the data migration task](https://docs.pingcap.com/tidb-data-migration/v2.0/migrate-data-using-dm#step-4-configure-the-data-migration-task).
