aws-sdk-go-v2 - Upload Manager - Upload a Folder to Amazon S3

Comment

package main

import (
	"context"
	"log"
	"os"
	"path/filepath"

	"github.com/aws/aws-sdk-go-v2/aws"
	"github.com/aws/aws-sdk-go-v2/config"
	"github.com/aws/aws-sdk-go-v2/feature/s3/manager"
	"github.com/aws/aws-sdk-go-v2/service/s3"
)

var (
	localPath string
	bucket    string
	prefix    string
)

func init() {
	if len(os.Args) != 4 {
		log.Fatalln("Usage:", os.Args[0], "<local path> <bucket> <prefix>")
	}
	localPath = os.Args[1]
	bucket = os.Args[2]
	prefix = os.Args[3]
}

func main() {
	walker := make(fileWalk)
	go func() {
		// Gather the files to upload by walking the path recursively 
		if err := filepath.Walk(localPath, walker.Walk); err != nil {
			log.Fatalln("Walk failed:", err)
		}
		close(walker)
	}()

	cfg, err := config.LoadDefaultConfig(context.TODO())
	if err != nil {
		log.Fatalln("error:", err)
	}
	
	// For each file found walking, upload it to Amazon S3
	uploader := manager.NewUploader(s3.NewFromConfig(cfg))
	for path := range walker {
		rel, err := filepath.Rel(localPath, path)
		if err != nil {
			log.Fatalln("Unable to get relative path:", path, err)
		}
		file, err := os.Open(path)
		if err != nil {
			log.Println("Failed opening file", path, err)
			continue
		}
		defer file.Close()
		result, err := uploader.Upload(context.TODO(), &s3.PutObjectInput{
			Bucket: &bucket,
			Key:    aws.String(filepath.Join(prefix, rel)),
			Body:   file,
		})
		if err != nil {
			log.Fatalln("Failed to upload", path, err)
		}
		log.Println("Uploaded", path, result.Location)
	}
}

type fileWalk chan string

func (f fileWalk) Walk(path string, info os.FileInfo, err error) error {
	if err != nil {
		return err
	}
	if !info.IsDir() {
		f <- path
	}
	return nil
}

The following example uses the `path/filepath` package to recursively gather a list of files and upload them to the specified Amazon S3 bucket. The keys of the Amazon S3 objects are prefixed with the file’s relative path.
