Functions

func OptionallyEnableMlock

func OptionallyEnableMlock() error

OptionallyEnableMlock determines if mlock should be called, and if so enables mlock.

func VaultPluginTLSProvider

func VaultPluginTLSProvider(apiTLSConfig *api.TLSConfig) func() (*tls.Config, error)

VaultPluginTLSProvider is run inside a plugin and retrives the response wrapped TLS certificate from vault. It returns a configured TLS Config.

Types

type APIClientMeta

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

func (*APIClientMeta) FlagSet

func (f *APIClientMeta) FlagSet() *flag.FlagSet

func (*APIClientMeta) GetTLSConfig

func (f *APIClientMeta) GetTLSConfig() *api.TLSConfig

type LookRunnerUtil

type LookRunnerUtil interface {
	Looker
	RunnerUtil
}

LookWrapper defines the functions for both Looker and Wrapper

type Looker

type Looker interface {
	LookupPlugin(string) (*PluginRunner, error)
}

Looker defines the plugin Lookup function that looks into the plugin catalog for availible plugins and returns a PluginRunner

type PluginRunner

type PluginRunner struct {
	Name           string                      `json:"name" structs:"name"`
	Command        string                      `json:"command" structs:"command"`
	Args           []string                    `json:"args" structs:"args"`
	Sha256         []byte                      `json:"sha256" structs:"sha256"`
	Builtin        bool                        `json:"builtin" structs:"builtin"`
	BuiltinFactory func() (interface{}, error) `json:"-" structs:"-"`
}

PluginRunner defines the metadata needed to run a plugin securely with go-plugin.

func (*PluginRunner) Run

func (r *PluginRunner) Run(wrapper RunnerUtil, pluginMap map[string]plugin.Plugin, hs plugin.HandshakeConfig, env []string) (*plugin.Client, error)

Run takes a wrapper instance, and the go-plugin paramaters and executes a plugin.

type RunnerUtil

type RunnerUtil interface {
	ResponseWrapData(data map[string]interface{}, ttl time.Duration, jwt bool) (*wrapping.ResponseWrapInfo, error)
	MlockEnabled() bool
}

Wrapper interface defines the functions needed by the runner to wrap the metadata needed to run a plugin process. This includes looking up Mlock configuration and wrapping data in a respose wrapped token.
