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("")
}
