Listing the CloudTrail Trails

This example uses the DescribeTrails operation to list the names of the CloudTrail trails and the bucket in which CloudTrail stores information in the us-west-2 region.

Choose Copy to save the code locally.

Create the file describe_trails.go. Add the following statements to import the Go and AWS SDK for Go packages used in the example.

import (
    "fmt"

    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/cloudtrail"
)

Initialize the session that the SDK uses to load credentials from the shared credentials file .aws/credentials in your home folder, and create a new service client.

sess := session.Must(session.NewSessionWithOptions(session.Options{
    SharedConfigState: session.SharedConfigEnable,
}))

// Create CloudTrail client
svc := cloudtrail.New(sess)

Call DescribeTrails. If an error occurs, print the error and exit. If no error occurs, loop through the trails, printing the name of each trail and the bucket.

resp, err := svc.DescribeTrails(&cloudtrail.DescribeTrailsInput{TrailNameList: nil})
if err != nil {
    fmt.Println("Got error calling CreateTrail:")
    fmt.Println(err.Error())
    return
}

fmt.Println("Found", len(resp.TrailList), "trail(s)")
fmt.Println("")

for _, trail := range resp.TrailList {
    fmt.Println("Trail name:  " + *trail.Name)
    fmt.Println("Bucket name: " + *trail.S3BucketName)
    fmt.Println("")
}
