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 (
"fmt"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/credentials"
"github.com/aws/aws-sdk-go/service/ec2"
)
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 {
panic(err)
}
// 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
