Types

type Credentials

type Credentials interface {
	// NewTokenProvider returns a new TokenProvider for the given key
	NewTokenProvider(key string, opts ...TokenOption) TokenProvider
}

func New

func New(thelmaConfig config.Config, thelmaRoot root.Root) (Credentials, error)

New returns a new Credentials instance using a directory store rooted at credentialsDir

func NewWithStore

func NewWithStore(store stores.Store) Credentials

NewWithStore returns a new Credentials instance backed by the given store

type TokenOption

type TokenOption func(*TokenOptions)

TokenOption function for configuring a token's Options

type TokenOptions

type TokenOptions struct {
	// EnvVar (optional) environment variable to use for this token. Defaults to key (upper-cased with s/-/_/, eg. "vault-token" -> "VAULT_TOKEN")
	EnvVar string
	// PromptEnabled (optional) if true, user will be prompted to manually enter a token value if one does not exist in credential store.
	PromptEnabled bool
	// PromptMessage (optional) Override default prompt message ("Please enter VAULT_TOKEN: ")
	PromptMessage string
	// ValidateFn (optional) Optional function for validating a token. If supplied, stored credentials will be validated before being returned to caller
	ValidateFn func([]byte) error
	// RefreshFn (optional) Optional function for refreshing a token. Called if a stored credential turns out to be invalid. If an error is returned, IssueFn will be called to issue a new credential.
	RefreshFn func([]byte) ([]byte, error)
	// IssueFn (optional) Optional function for issuing a new token. If supplied, prompt options are ignored.
	IssueFn func() ([]byte, error)
	// CredentialStore (optional) Use a custom credential store instead of the default store (~/.thelma/credentials/$key)
	CredentialStore stores.Store
}

TokenOptions configuration options for a TokenProvider

type TokenProvider

type TokenProvider interface {
	// Get returns the value of the token. Based on the token's options, it will attempt to resolve a value for
	// the token by:
	// (1) Looking it up in environment variables
	// (2) Looking it up in local credential store (~/.thelma/credentials)
	// (3) Issue a new token (if issuer function configured)
	// (4) Prompting user for value (if enabled)
	// If none of the token resolution options succeed an error is returned.
	Get() ([]byte, error)
	// Reissue forces re-issue of the token, without checking environment variables or for a valid existing
	// credential in the store
	Reissue() ([]byte, error)
}

TokenProvider manages a token used for authentication, possibly stored on the local filesystem
