You can call the DescribeClusterAddonsVersion operation to query the components that are installed in a specified Container Service for Kubernetes (ACK) cluster.

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.
