Description

Provides cluster-level details including status, hardware and software configuration, VPC settings, and so on. For information about the cluster steps, see ListSteps .

Creating a Request

describeCluster #

Arguments

:: Text	`dcClusterId`
-> DescribeCluster

Creates a value of DescribeCluster with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

dcClusterId - The identifier of the cluster to describe.

data DescribeCluster #

This input determines which cluster to describe.

See: describeCluster smart constructor.

Request Lenses

dcClusterId :: Lens' DescribeCluster Text #

The identifier of the cluster to describe.

Destructuring the Response

describeClusterResponse #

Arguments

:: Int	`dcrsResponseStatus`
-> Cluster	`dcrsCluster`
-> DescribeClusterResponse

Creates a value of DescribeClusterResponse with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

dcrsResponseStatus - -- | The response status code.
dcrsCluster - This output contains the details for the requested cluster.

data DescribeClusterResponse #

This output contains the description of the cluster.

See: describeClusterResponse smart constructor.
