	// contains filtered or unexported fields
}

Client is the client to the Vault API. Create a client with NewClient.

func NewClient

func NewClient(c *Config) (*Client, error)

NewClient returns a new client for the given configuration.

If the configuration is nil, Vault will use configuration from DefaultConfig(), which is the recommended starting configuration.

If the environment variable `VAULT_TOKEN` is present, the token will be automatically added to the client. Otherwise, you must manually call `SetToken()`.

ClearToken deletes the token if it is set or does nothing otherwise.

func (*Client) Clone

func (c *Client) Clone() (*Client, error)

Clone creates a new client with the same configuration. Note that the same underlying http.Client is used; modifying the client from more than one goroutine at once may not be safe, so modify the client as needed and then clone.

Also, only the client's config is currently copied; this means items not in the api.Config struct, such as policy override and wrapping function behavior, must currently then be set as desired on the new client.

func (*Client) CurrentWrappingLookupFunc

func (c *Client) CurrentWrappingLookupFunc() WrappingLookupFunc

CurrentWrappingLookupFunc sets a lookup function that returns desired wrap TTLs for a given operation and path

func (*Client) Headers

func (c *Client) Headers() http.Header

Headers gets the current set of headers used for requests. This returns a copy; to modify it make modifications locally and use SetHeaders.

func (*Client) Help

func (c *Client) Help(path string) (*Help, error)

Help reads the help information for the given path.

func (*Client) Logical

func (c *Client) Logical() *Logical

Logical is used to return the client for logical-backend API calls.

func (*Client) OutputCurlString

func (c *Client) OutputCurlString() bool

func (*Client) RawRequest

func (c *Client) RawRequest(r *Request) (*Response, error)

func (*Client) RawRequestWithContext

func (c *Client) RawRequestWithContext(ctx context.Context, r *Request) (*Response, error)

RawRequestWithContext performs the raw request given. This request may be against a Vault server not configured with this client. This is an advanced operation that generally won't need to be called externally.

func (*Client) SSH

func (c *Client) SSH() *SSH

SSH returns the client for logical-backend API calls.

func (*Client) SSHHelper

func (c *Client) SSHHelper() *SSHHelper

SSHHelper creates an SSHHelper object which can talk to Vault server with SSH backend mounted at default path ("ssh").

func (*Client) SSHHelperWithMountPoint

func (c *Client) SSHHelperWithMountPoint(mountPoint string) *SSHHelper

SSHHelperWithMountPoint creates an SSHHelper object which can talk to Vault server with SSH backend mounted at a specific mount point.

func (*Client) SSHWithMountPoint

SSHWithMountPoint returns the client with specific SSH mount point.

func (*Client) SetAddress

func (c *Client) SetAddress(addr string) error

Sets the address of Vault in the client. The format of address should be "<Scheme>://<Host>:<Port>". Setting this on a client will override the value of VAULT_ADDR environment variable.

func (*Client) SetBackoff

func (c *Client) SetBackoff(backoff retryablehttp.Backoff)

SetBackoff sets the backoff function to be used for future requests.

func (*Client) SetClientTimeout

func (*Client) SetToken

func (c *Client) SetToken(v string)

SetToken sets the token directly. This won't perform any auth verification, it simply sets the token properly for future requests.

func (*Client) SetWrappingLookupFunc

func (c *Client) SetWrappingLookupFunc(lookupFunc WrappingLookupFunc)

SetWrappingLookupFunc sets a lookup function that returns desired wrap TTLs for a given operation and path

func (*Client) Sys

func (c *Client) Sys() *Sys

Sys is used to return the client for sys-related API calls.

func (*Client) Token

func (c *Client) Token() string

Token returns the access token being used by this client. It will return the empty string if there is no token set.

type Config

type Config struct {

	// Address is the address of the Vault server. This should be a complete
	// URL such as "http://vault.example.com". If you need a custom SSL
	// cert or want to enable insecure mode, you need to specify a custom
	// HttpClient.
	Address string

	// AgentAddress is the address of the local Vault agent. This should be a
	// complete URL such as "http://vault.example.com".
	AgentAddress string

	// HttpClient is the HTTP client to use. Vault sets sane defaults for the
	// http.Client and its associated http.Transport created in DefaultConfig.
	// If you must modify Vault's defaults, it is suggested that you start with
	// that client and modify as needed rather than start with an empty client
	// (or http.DefaultClient).
	HttpClient *http.Client

	// MaxRetries controls the maximum number of times to retry when a 5xx
	// error occurs. Set to 0 to disable retrying. Defaults to 2 (for a total
	// of three tries).
	MaxRetries int

	// Timeout is for setting custom timeout parameter in the HttpClient
	Timeout time.Duration

	// If there is an error when creating the configuration, this will be the
	// error
	Error error

	// The Backoff function to use; a default is used if not provided
	Backoff retryablehttp.Backoff

	// Limiter is the rate limiter used by the client.
	// If this pointer is nil, then there will be no limit set.
	// In contrast, if this pointer is set, even to an empty struct,
	// then that limiter will be used. Note that an empty Limiter
	// is equivalent blocking all events.
	Limiter *rate.Limiter

	// OutputCurlString causes the actual request to return an error of type
	// *OutputStringError. Type asserting the error message will allow
	// fetching a cURL-compatible string for the operation.
	//
	// Note: It is not thread-safe to set this and make concurrent requests
	// with the same client. Cloning a client will not clone this value.
	OutputCurlString bool
	// contains filtered or unexported fields
}

Config is used to configure the creation of the client.

func DefaultConfig

func DefaultConfig() *Config

DefaultConfig returns a default configuration for the client. It is safe to modify the return value of this function.

The default Address is https://127.0.0.1:8200, but this can be overridden by setting the `VAULT_ADDR` environment variable.

If an error is encountered, this will return nil.

func (*Config) ConfigureTLS

func (c *Config) ConfigureTLS(t *TLSConfig) error

			log.Fatal(err)
		}

		// Renewal is now over
	case renewal := <-renewer.RenewCh():
		log.Printf("Successfully renewed: %#v", renewal)
	}
}

The `DoneCh` will return if renewal fails or if the remaining lease duration after a renewal is less than or equal to the grace (in number of seconds). In both cases, the caller should attempt a re-read of the secret. Clients should check the return value of the channel to see if renewal was successful.

	Rand *rand.Rand

	// RenewBuffer is the size of the buffered channel where renew messages are
	// dispatched.
	RenewBuffer int

	// The new TTL, in seconds, that should be set on the lease. The TTL set
