Golang : List available AWS regions

Problem :

You need to get ALL the available AWS regions accessible by you. How to do that in Golang ?

Solution :

Use the EC2.DescribeRegions() function to get the list of available AWS regions. You can see a full list of ALL the AWS regions at http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region

Here you go. Happy Coding!

 package main

 import (

 func main() {

 aws_access_key_id := "<replace with yours>"
 aws_secret_access_key := "<replace with yours>"

 // If you're working with temporary security credentials,
 // you can also keep the session token in AWS_SESSION_TOKEN.

 token := ""

 creds := credentials.NewStaticCredentials(aws_access_key_id, aws_secret_access_key, token)

 ec2client := ec2.New(&aws.Config{
 Region: "eu-west-1", // get from your AWS console, click "Properties"
 Credentials: creds,
 LogLevel: 0,

 regions, err := ec2client.DescribeRegions(&ec2.DescribeRegionsInput{})

 if err != nil {

 // see https://godoc.org/github.com/aws/aws-sdk-go/service/ec2#Region
 for _, region := range regions.Regions {
 fmt.Println("Region Name : ", *region.RegionName)
 fmt.Println("Region Endpoint : ", *region.Endpoint)


Sample output :

Region Name : eu-central-1

Region Endpoint : ec2.eu-central-1.amazonaws.com

Region Name : sa-east-1

Region Endpoint : ec2.sa-east-1.amazonaws.com

Region Name : ap-northeast-1

Region Endpoint : ec2.ap-northeast-1.amazonaws.com

Region Name : eu-west-1

Region Endpoint : ec2.eu-west-1.amazonaws.com

Region Name : us-east-1

Region Endpoint : ec2.us-east-1.amazonaws.com

Region Name : us-west-1

Region Endpoint : ec2.us-west-1.amazonaws.com

Region Name : us-west-2

Region Endpoint : ec2.us-west-2.amazonaws.com

Region Name : ap-southeast-2

Region Endpoint : ec2.ap-southeast-2.amazonaws.com

Region Name : ap-southeast-1

Region Endpoint : ec2.ap-southeast-1.amazonaws.com
