AWS SDK for Go
Developer Guide

Displaying Information about All Lambda Functions

First import the packages we use in this example.

import ( "github.com/aws/aws-sdk-go/aws" "github.com/aws/aws-sdk-go/aws/session" "github.com/aws/aws-sdk-go/service/lambda" "fmt" "os" )

Next, create the session and Lambda client.

sess := session.Must(session.NewSessionWithOptions(session.Options{ SharedConfigState: session.SharedConfigEnable, })) svc := lambda.New(sess, &aws.Config{Region: aws.String("us-west-2")})

Next, call ListFunctions and exit if there is an error.

result, err := svc.ListFunctions(nil) if err != nil { fmt.Println("Cannot list functions") os.Exit(0) }

Finally, display the names and descriptions of the Lambda functions.

fmt.Println("Functions:") for _, f := range result.Functions { fmt.Println("Name: " + aws.StringValue(f.FunctionName)) fmt.Println("Description: " + aws.StringValue(f.Description)) fmt.Println("") }
