Vanadium

This repository contains a reference implementation of the Vanadium APIs.

Unlike the APIs in https://github.com/vanadium/go.v23, which promises to provide backward compatibility this repository makes no such promises.

Overview

Package ref defines constants used through the Vanadium reference implementation, which is implemented in its subdirectories.

Constants

const (
	// EnvCredentials is the name of the environment variable pointing to a
	// directory containing all the credentials of a principal (the blessing
	// store, the blessing roots, possibly the private key etc.).

	// indicating whether an agent should be started to serve credentials to
	// be loaded from a directory.  If set to anything but empty string, no
	// attempt is made to load an agent.
	//
	// Typically used in tests or on platforms where launching agents is not
	// desirable.

	EnvCredentialsNoAgent = "V23_CREDENTIALS_NO_AGENT"

	// socket of the agent process containing all the credentials for a
	// principal (the blessing store, the blessing roots, possibly the
	// private key etc.).

	// pointing to a comma-separated list of i18n catalogue files to be
	// loaded at startup.
	EnvI18nCatalogueFiles = "V23_I18N_CATALOGUE"

	// EnvOAuthIdentityProvider is the name of the environment variable
	// pointing to the url of the OAuth identity provider used by the
	// principal seekblessings command.
	EnvOAuthIdentityProvider = "V23_OAUTH_IDENTITY_PROVIDER"

	// When EnvExpectGoogleComputeEngine is set and non-empty, the runtime
	// initialization will fail if the GCE metadata is inaccessible.

Functions

func EnvClearCredentials

func EnvClearCredentials() error

EnvClearCredentials unsets all environment variables that are used by the Runtime to intialize the principal.

func EnvNamespaceRoots

func EnvNamespaceRoots() (map[string]string, []string)

EnvNamespaceRoots returns the set of namespace roots to be used by the process, as specified by environment variables.

It returns both a map of environment variable name to value and the list of values.
