Golang : Create S3 bucket with official aws-sdk-go package
This is just one of the updates/supplementary tutorials to the previous tutorial on how to upload to AWS S3. This tutorial will use the official AWS-SDK-GO package to create a bucket in AWS S3.
NOTE : As of the time of writing this, the AWS-SDK-GO package is still undergoing radical changes and if the code below somehow refused to work properly. Chances are AWS-SDK-GO packages lose internal organs here and there during the metamorphosis period.
Here you go :
package main
import (
"fmt"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/awserr"
"github.com/aws/aws-sdk-go/aws/credentials"
"github.com/aws/aws-sdk-go/service/s3"
"os"
)
func main() {
// DO NOT PUT credentials in code for production usage!
// see https://www.socketloop.com/tutorials/golang-setting-up-configure-aws-credentials-with-official-aws-sdk-go
// on setting credentials from environment or loading from file
// this is just for demo/tutorial purpose
aws_access_key_id := "<replace with yours>"
aws_secret_access_key := "<replace with yours>"
token := ""
creds := credentials.NewStaticCredentials(aws_access_key_id, aws_secret_access_key, token)
_, err := creds.Get()
if err != nil {
fmt.Println(err)
os.Exit(1)
}
aws.DefaultConfig.Region = "us-west-2"
s3client := s3.New(&aws.Config{
Region: "us-west-2", // S3 suppose to be global and regionless.. no harm putting this here
Credentials: creds,
LogLevel: 0,
})
// see http://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html
// for bucket naming rules if you get the error message
// InvalidBucketName The specified bucket is not valid. <nil>
//bucketName := "mynewBucket" <--- will NOT work
bucketName := "ttestmynewbucket"
params := &s3.CreateBucketInput{
Bucket: aws.String(bucketName),
// commented out these as they will cause error. Bug ?
//GrantFullControl: aws.String("GrantFullControl"),
//GrantRead: aws.String("GrantRead"),
//GrantReadACP: aws.String("GrantReadACP"),
//GrantWrite: aws.String("GrantWrite"),
//GrantWriteACP: aws.String("GrantWriteACP"),
}
result, err := s3client.CreateBucket(params)
//if err != nil {
// fmt.Println(err)
// return
// }
if err != nil {
if awsErr, ok := err.(awserr.Error); ok {
// Generic AWS Error with Code, Message, and original error (if any)
fmt.Println(awsErr.Code(), awsErr.Message(), awsErr.OrigErr())
if reqErr, ok := err.(awserr.RequestFailure); ok {
// A service error occurred
fmt.Println(reqErr.Code(), reqErr.Message(), reqErr.StatusCode(), reqErr.RequestID())
}
} else {
// This case should never be hit, The SDK should alwsy return an
// error which satisfies the awserr.Error interface.
fmt.Println(err.Error())
}
}
fmt.Println("Bucket created in ", *result.Location)
}
Output :
Bucket created in http://ttestmynewbucket.s3.amazonaws.com/
