Imports or migrates one or more Elastic Compute Service (ECS) instances to a cluster.


When you call this operation to import an ECS instance, the operating system of the ECS instance will be reinstalled. After the operating system is reinstalled, all data on the ECS instance will be deleted and you must set a logon password for the ECS instance again. Make sure that no important data exists or data has been backed up on the ECS instance that you want to import.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
