Overview

Package 'dir' implements the "directory backend". It uses a regular filesystem directories/files to store Teleport auth server state.

Limitations:

• key names cannot start with '.' (dot)

Functions

func GetName

func GetName() string

GetName

func New

func New(params backend.Params) (backend.Backend, error)

New creates a new instance of Filesystem backend, it conforms to backend.NewFunc API

Types

type Backend

type Backend struct {
	// RootDir is the root (home) directory where the backend
	// stores all the data.
	RootDir string

	// InternalClock is a test-friendly source of current time
	InternalClock clockwork.Clock

	*log.Entry
}

fs.Backend implements backend.Backend interface using a regular POSIX-style filesystem

func (*Backend) AcquireLock

func (bk *Backend) AcquireLock(token string, ttl time.Duration) (err error)

AcquireLock grabs a lock that will be released automatically in TTL

func (*Backend) Clock

func (b *Backend) Clock() clockwork.Clock

func (*Backend) Close

func (bk *Backend) Close() error

Close releases the resources taken up by a backend

func (*Backend) CreateVal

func (bk *Backend) CreateVal(bucket []string, key string, val []byte, ttl time.Duration) error

CreateVal creates value with a given TTL and key in the bucket if the value already exists, returns AlreadyExistsError

func (*Backend) DeleteBucket

func (bk *Backend) DeleteBucket(parent []string, bucket string) error

DeleteBucket deletes the bucket by a given path

func (*Backend) DeleteKey

func (bk *Backend) DeleteKey(bucket []string, key string) error

DeleteKey deletes a key in a bucket

func (*Backend) GetItems

func (bk *Backend) GetItems(bucket []string) ([]backend.Item, error)

GetItems is a function that returns keys in batch

func (*Backend) GetKeys

func (bk *Backend) GetKeys(bucket []string) ([]string, error)

GetKeys returns a list of keys for a given path

func (*Backend) GetVal

func (bk *Backend) GetVal(bucket []string, key string) ([]byte, error)

GetVal return a value for a given key in the bucket

func (*Backend) ReleaseLock

func (bk *Backend) ReleaseLock(token string) (err error)

ReleaseLock forces lock release before TTL

func (*Backend) UpsertVal

func (bk *Backend) UpsertVal(bucket []string, key string, val []byte, ttl time.Duration) error

UpsertVal updates or inserts value with a given TTL into a bucket ForeverTTL for no TTL
