Golang

This Go program demonstrates how to interact with an S3-compatible service using the AWS SDK for Go. The program lists all available S3 buckets. Please use aws-sdk-go V1 version as follows.

Prerequisites

To run this program, you'll need:

• Go installed on your machine (https://golang.org/doc/install).

• AWS SDK for Go installed. You can get it using:

  go get github.com/aws/aws-sdk-go

• Access credentials (Access Key ID and Secret Access Key) for the S3-compatible service you are connecting to.

Code

package main

import (
	"fmt"
	"log"

	"github.com/aws/aws-sdk-go/aws"
	"github"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() {
	// Set the S3 compatible service information
	accessKey := "YOUR_ACCESS_KEY"
	secretKey := "YOUR_SECRET_KEY"
	endpoint := "HOST_NAME" //Use the Hostname from the Details page.
	region := "US"

	// Create a session
	s3Config := &aws.Config{
		Credentials:      credentials.NewStaticCredentials(accessKey, secretKey, ""),
		Endpoint:         aws.String(endpoint),
		Region:           aws.String(region),
		S3ForcePathStyle: aws.Bool(true), // Use path-style instead of virtual host style
	}

	sess, err := session.NewSession(s3Config)
	if err != nil {
		log.Fatalf("Failed to create session: %v", err)
	}

	// Create S3 service client
	svc := s3.New(sess)

	// List all buckets
	fmt.Println("Attempting to list buckets...")
	result, err := svc.ListBuckets(nil)
	if err != nil {
		log.Fatalf("Failed to list buckets: %v", err)
	}

	fmt.Println("Successfully connected! Current buckets:")
	for _, bucket := range result.Buckets {
		fmt.Printf("  - %s
", *bucket.Name)
	}
}

Explanation

1. Setting up the S3 Configuration:

   • The program starts by setting the AWS access key, secret key, and endpoint of the S3-compatible service. The region is also set to us.

   • S3ForcePathStyle is set to true to use path-style addressing rather than virtual host style.

2. Creating a Session:

   • A new session is created using the configuration parameters. If the session creation fails, the program logs an error and exits.

3. Listing Buckets:

   • The program uses the ListBuckets API to retrieve all available buckets. If the request is successful, it prints out the names of the buckets.

Running the Program

1. Save the above code to a file, for example, main.go.

2. Run the program using the following command:

   go run main.go

3. The output will display the names of the S3 buckets.

Example Output

Attempting to list buckets...
Successfully connected! Current buckets:
  - my-bucket-name-1
  - my-bucket-name-2
  - my-bucket-name-3

Notes

• Make sure your AWS credentials (Access Key and Secret Key) are correctly set.

• The program will list the buckets available at the specified S3-compatible service endpoint.
