s3fs

Package s3fs provides a S3 implementation for Go1.16 filesystem interface.

Since S3 is a flat structure, s3fs simulates directories by using prefixes and "/" delim. ModTime on directories is always zero value.

The implementation wraps aws sdk go s3 client.

const bucket = "my-bucket"

s, err := session.NewSession()
if err != nil {
    log.Fatal(err)
}

s3fs := s3fs.New(s3.New(s), bucket)

// print out all files in s3 bucket.
_ = fs.WalkDir(s3fs, ".", func(path string, d fs.DirEntry, err error) error {
    if err != nil {
        return err
    }

    if d.IsDir() {
        fmt.Println("dir:", path)
        return nil
    }
    fmt.Println("file:", path)
    return nil
})

  • func (f *S3FS) Open(name string) (fs.File, error)

Types

type S3FS

type S3FS struct {
	// contains filtered or unexported fields
}

S3FS is a S3 filesystem implementation.

S3 has a flat structure instead of a hierarchy. S3FS simulates directories by using prefixes and delims ("/"). Because directories are simulated, ModTime is always a default Time value (IsZero returns true).

func New

func New(cl s3iface.S3API, bucket string) *S3FS

New returns a new filesystem that works on the specified bucket.

func (*S3FS) Open

func (f *S3FS) Open(name string) (fs.File, error)

Open implements fs.FS.

func (*S3FS) ReadDir

func (f *S3FS) ReadDir(name string) ([]fs.DirEntry, error)

ReadDir implements fs.ReadDirFS.

func (*S3FS) Stat

func (f *S3FS) Stat(name string) (fs.FileInfo, error)

Stat implements fs.StatFS.
