AWS SDK for Go

API Reference Join the chat at Build Status Apache V2 License

aws-sdk-go is the official AWS SDK for the Go programming language.

Checkout our release notes for information about the latest bug fixes, updates, and features added to the SDK.

Release v0.9.0rc1 introduced a breaking change to the SDK. See the release notes for details of the change and instructions to migrate to the latest SDK version.


The SDK is currently in the process of being developed, and not everything may be working fully yet. Please be patient and report any bugs or problems you experience. The APIs may change radically without much warning, so please vendor your dependencies with Godep or similar.

Please do not confuse this for a stable, feature-complete library.

Note that while most AWS protocols are currently supported, not all services available in this package are implemented fully, as some require extra customizations to work with the SDK. If you've encountered such a scenario, please open a GitHub issue so we can track work for the service.


Install your specific service package with the following go get command. For example, EC2 support might be installed with:

$ go get

You can also install the entire SDK by installing the root package, including all of the SDK's dependencies:

$ go get -u

Configuring Credentials

Before using the SDK, ensure that you've configured credentials. The best way to configure credentials on a development machine is to use the ~/.aws/credentials file, which might look like:

aws_access_key_id = AKID1234567890
aws_secret_access_key = MY-SECRET-KEY

You can learn more about the credentials file from this blog post.

Alternatively, you can set the following environment variables:



To use a service in the SDK, create a service variable by calling the New() function. Once you have a service, you can call API operations which each return response data and a possible error.

To list a set of instance IDs from EC2, you could run:

package main

import (


func main() {
	// Create an EC2 service object in the "us-west-2" region
	// Note that you can also configure your region globally by
	// exporting the AWS_REGION environment variable
	svc := ec2.New(&aws.Config{Region: aws.String("us-west-2")})

	// Call the DescribeInstances Operation
	resp, err := svc.DescribeInstances(nil)
	if err != nil {

	// resp has all of the response data, pull out instance IDs:
	fmt.Println("> Number of reservation sets: ", len(resp.Reservations))
	for idx, res := range resp.Reservations {
		fmt.Println("  > Number of instances: ", len(res.Instances))
		for _, inst := range resp.Reservations[idx].Instances {
			fmt.Println("    - Instance ID: ", *inst.InstanceID)

You can find more information and operations in our API documentation.
