DescribeTemplates - Container Service for Kubernetes - Alibaba Cloud Documentation Center

An orchestration template defines and describes a group of Kubernetes resources. It declaratively describes the configuration of an application or how an application runs. You can call the DescribeTemplates API operation to query orchestration templates and their detailed information, including access permissions, YAML content, and labels.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
