func ExecScript added in v0.1.2

func ExecScript(script string) (*exec.Cmd, error)

ExecScript returns a command to execute a script

func ExternalTokenHelperPath added in v0.5.0

func ExternalTokenHelperPath(path string) (string, error)

ExternalTokenHelperPath takes the configured path to a helper and expands it to a full absolute path that can be executed. As of 0.5, the default token helper is internal, to avoid problems running in dev mode (see GH-850 and GH-783), so special assumptions of prepending "vault token-" no longer apply.

As an additional result, only absolute paths are now allowed. Looking in the path or a current directory for an arbitrary executable could allow someone to switch the expected binary for one further up the path (or in the current directory), potentially opening up execution of an arbitrary binary.

func Test

func Test(t *testing.T, h TokenHelper)

Test is a public function that can be used in other tests to test that a helper is functioning properly.

func TestExternalTokenHelperProcessCLI added in v0.5.0

func TestExternalTokenHelperProcessCLI(t *testing.T, cmd cli.Command)

TestExternalTokenHelperProcessCLI can be called to implement TestExternalTokenHelperProcess for TestProcess that just executes a CLI command.

func TestProcess

func TestProcess(t *testing.T, s ...string)

TestProcess is used to re-execute this test in order to use it as the helper process. For this to work, the TestExternalTokenHelperProcess function must exist.

func TestProcessPath

func TestProcessPath(t *testing.T, s ...string) string

TestProcessPath returns the path to the test process.


type ExternalTokenHelper added in v0.5.0

type ExternalTokenHelper struct {
	BinaryPath string
	Env        []string

ExternalTokenHelper is the struct that has all the logic for storing and retrieving tokens from the token helper. The API for the helpers is simple: the BinaryPath is executed within a shell with environment Env. The last argument appended will be the operation, which is:

* "get" - Read the value of the token and write it to stdout.
* "store" - Store the value of the token which is on stdin. Output
* "erase" - Erase the contents stored. Output nothing.

Any errors can be written on stdout. If the helper exits with a non-zero exit code then the stderr will be made part of the error value.

func (*ExternalTokenHelper) Erase added in v0.5.0

func (h *ExternalTokenHelper) Erase() error

Erase deletes the contents from the helper.

func (*ExternalTokenHelper) Get added in v0.5.0

func (h *ExternalTokenHelper) Get() (string, error)

Get gets the token value from the helper.

func (*ExternalTokenHelper) Path added in v0.5.0

func (h *ExternalTokenHelper) Path() string

func (*ExternalTokenHelper) Store added in v0.5.0

func (h *ExternalTokenHelper) Store(v string) error

Store stores the token value into the helper.

type InternalTokenHelper added in v0.5.0

type InternalTokenHelper struct {
	// contains filtered or unexported fields

InternalTokenHelper fulfills the TokenHelper interface when no external token-helper is configured, and avoids shelling out

func (*InternalTokenHelper) Erase added in v0.5.0

func (i *InternalTokenHelper) Erase() error

Erase erases the value of the token

func (*InternalTokenHelper) Get added in v0.5.0

func (i *InternalTokenHelper) Get() (string, error)

Get gets the value of the stored token, if any

func (*InternalTokenHelper) Path added in v0.5.0

func (i *InternalTokenHelper) Path() string

func (*InternalTokenHelper) Store added in v0.5.0

func (i *InternalTokenHelper) Store(input string) error

Store stores the value of the token to the file

type TokenHelper added in v0.5.0

type TokenHelper interface {
	// Path displays a backend-specific path; for the internal helper this
	// is the location of the token stored on disk; for the external helper
	// this is the location of the binary being invoked
	Path() string

	Erase() error
	Get() (string, error)
	Store(string) error

TokenHelper is an interface that contains basic operations that must be implemented by a token helper
