Call the ModifyInstance operation to modify the specifications of a bastion host - Bastionhost

Bastionhost does not provide an API operation to modify the specifications of a bastion host. To modify the specifications of a bastion host, you can call the ModifyInstance operation of the Transactions and Bills Management (BSS) API.

Background information

The BSS API is a set of common operations used to manage Alibaba Cloud resources. For example, you can call the operations to query service prices, manage instances, or obtain bills. For more information about the operations of the BSS API, see API Overview.

You can call the ModifyInstance operation to modify the specifications of a bastion host. For more information about how to call the operation, see Request Structure.

This topic describes how to call the ModifyInstance operation to modify the specifications of a bastion host and provides examples.

Debugging

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.
