Quick Start

package main

import (
    "context"
    "encoding/hex"
    "fmt"
    "io"
    "log"
    "os"
    
    "github.com/aws/aws-sdk-go-v2/aws"
    "github.com/aws/aws-sdk-go-v2/config"
    
    ebsfile "github.com/masahiro331/go-ebs-file"
)

var _ aws.CredentialsProvider = &DummyCredentialProvider{}

type DummyCredentialProvider struct{}

func (p *DummyCredentialProvider) Retrieve(ctx context.Context) (aws.Credentials, error) {
    return aws.Credentials{
        AccessKeyID:     "YOUR_ACCESS_KEY",
        SecretAccessKey: "YOUR_SECRET_KEY",
    }, nil
}

func main() {
    var rs io.ReadSeeker
    cli, err := ebsfile.New(context.TODO(),
            config.WithRegion("YOUR_REGION"),
            config.WithCredentialsProvider(&DummyCredentialProvider{}),
        )
    if err != nil {
        log.Fatal(err)
    }
    
    rs, err = ebsfile.Open(os.Args[1], context.Background(), nil, cli)
    if err != nil {
        log.Fatal(err)
    }
    
    buf := make([]byte, 512)
    rs.Read(buf)
    fmt.Println(hex.Dump(buf))
}
