package main import ( "context" "fmt" "github.com/aws/aws-sdk-go-v2/aws" "github.com/aws/aws-sdk-go-v2/config" "github.com/aws/aws-sdk-go-v2/service/redshift" ) // main uses the AWS SDK for Go V2 to create a Redshift client // and list up to 10 clusters in your account. // This example uses the default settings specified in your shared credentials // and config files. func main() { ctx := context.Background() sdkConfig, err := config.LoadDefaultConfig(ctx) if err != nil { fmt.Println("Couldn't load default configuration. Have you set up your AWS account?") fmt.Println(err) return } redshiftClient := redshift.NewFromConfig(sdkConfig) count := 20 fmt.Printf("Let's list up to %v clusters for your account.\n", count) result, err := redshiftClient.DescribeClusters(ctx, &redshift.DescribeClustersInput{ MaxRecords: aws.Int32(int32(count)), }) if err != nil { fmt.Printf("Couldn't list clusters for your account.
