How to run AWS SDK with credentials from variables?

I used environment variables before and it worked fine.

Now I am migrating my config variables into a single file and I have AWS_SECRET_ACCESS_KEY and AWS_ACCESS_KEY_ID variables containing respective values that are loaded from this file.

I tried this code but receiving an error:

creds := credentials.NewStaticCredentials("123", conf.AWS_SECRET_ACCESS_KEY, conf.AWS_ACCESS_KEY_ID)
sess, err := session.NewSession(&aws.Config{Credentials: creds})

Here is the error
> InvalidClientTokenId: The security token included in the request is invalid.

How do I properly inject my keys into the aws sdk calls?

Try re-ordering your args so that ACCESS_KEY is the 1st param and SECRET_KEY is the second:

creds := credentials.NewStaticCredentials(conf.AWS_ACCESS_KEY_ID, conf.AWS_SECRET_ACCESS_KEY, "")

Try adding the region as well:

sess, err := session.NewSession(&aws.Config{
    Region:      aws.String("us-west-2"),
    Credentials: credentials.NewStaticCredentials(conf.AWS_ACCESS_KEY_ID, conf.AWS_SECRET_ACCESS_KEY, ""),
})

Or you can just temporaly set Environment variables.

package main
import (
	"fmt"
	"os"
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/s3/s3manager"
)

const (
    AccessKeyId     = "XXXXXXXXXXXXXXXXXX"
    SecretAccessKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    Region          = "eu-west-1"
    Bucket          = "XXXXX-XXXX-XXX"
)

func main() {
    os.Setenv("AWS_ACCESS_KEY_ID",     AccessKeyId)
    os.Setenv("AWS_SECRET_ACCESS_KEY", SecretAccessKey)

	filename := os.Args[1]

	file, err := os.Open(filename)
	if err != nil {
		fmt.Println("Failed to open file", filename, err)
		os.Exit(1)
	}
	defer file.Close()

	conf := aws.Config{Region: aws.String(Region)}
	sess := session.New(&conf)
   
	svc := s3manager.NewUploader(sess)

	fmt.Println("Uploading file to S3...")
	result, err := svc.Upload(&s3manager.UploadInput{
		Bucket: aws.String(Bucket),
		Key:    aws.String(filepath.Base(filename)),
		Body:   file,
	})
	if err != nil {
		fmt.Println("error", err)
		os.Exit(1)
	}
}

Additionally, if you hadn't known, the SDK allows for the use of the shared config under .aws/config. You can put your values in there and then set the environment variable AWS_SDK_LOAD_CONFIG to a truthy value to load the shared config. An example shared config would look like this:

[default]
aws_access_key_id = AKID
aws_secret_access_key = SECRET

Then running:

AWS_SDK_LOAD_CONFIG=true go run main.go

You can pass the creds variable to the aws.Config struct to set the AWS credentials for the S3 session.

> You need to import the github.com/aws/aws-sdk-go/aws/credentials package.

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/aws/session"
	"github.com/aws/aws-sdk-go/service/s3"
)

func main() {
	accessKey := "ACCESS"
	secretKey := "SECRET"
	creds := credentials.NewStaticCredentials(accessKey, secretKey, "")

	sess, err := session.NewSession(&aws.Config{
		Credentials: creds,
		Endpoint:    aws.String("ENDPOINT"),
		Region:      aws.String("REGION"),
	})
	if err != nil {
		panic(err)
	}

	svc := s3.New(sess)

	bucketName := "ramingotestsdk"

	_, err = svc.CreateBucket(&s3.CreateBucketInput{
		Bucket: aws.String(bucketName),
	})
	if err != nil {
		panic(err)
	}

	fmt.Printf("Bucket %s created\n", bucketName)
}

OUTPUT:

Bucket ramingotestsdk created

Hi you have the option to utilize your configurations within an aws.Credentials struct, as demonstrated in the code snippet below.

package services
import (
"context"
"fmt"
"ldapmng/config"
"time"
"github.com/aws/aws-sdk-go-v2/aws"
"github.com/aws/aws-sdk-go-v2/credentials"
"github.com/aws/aws-sdk-go-v2/service/directoryservice"
)
type AwsService struct {
Ds *directoryservice.Client
}
func NewAwsService(ctx context.Context) (*AwsService, error) {
awsService := &AwsService{}
settings, _ := config.LoadSettings()
awsSessionExpiration, err := time.Parse("2006-01-02T15:04:05-07:00", settings.AwsSessionExpiration)
creds := aws.Credentials{
AccessKeyID:     settings.AwsAccessKeyId,
SecretAccessKey: settings.AwsSecretAccessKey,
SessionToken:    settings.AwsSessionToken,
// Source:          ,
// CanExpire:       false,
Expires: awsSessionExpiration,
}
credsProvider := credentials.StaticCredentialsProvider{
Value: creds,
}
cfg := aws.Config{
Region:      settings.AwsRegion,
Credentials: credsProvider,
}
if err != nil {
fmt.Println("Error loading AWS configuration:", err)
return nil, err
}
awsService.Ds = directoryservice.NewFromConfig(cfg)
return awsService, nil
}

Connect your sdk client using this generic service

var awsSession *session.Session
func init() {
initializeAwsSession()
}
func initializeAwsSession() {
awsSession = session.Must(session.NewSession(&aws.Config{
Region:      aws.String("ap-southeast-1"),
Credentials: credentials.NewStaticCredentials("YOUR_ACCESS_KEY","YOUR SECRET_KEY", ""),
}))
}
