Functions

func Configure

func Configure()

Configure called at the very top of main() the order of config follows the Viper conventions...

The priority of the sources is the following: 1. comand line flags 2. env. variables 3. config file 4. defaults

so we process these in backwards order (defaults then config file)

func Get

func Get(key string) string

Get string value for key

func InitForTestPurposes

func InitForTestPurposes()

InitForTestPurposes is called by most *_testing.go files in Vouch Proxy

func InitForTestPurposesWithProvider

func InitForTestPurposesWithProvider(provider string)

InitForTestPurposesWithProvider just for testing

func UnmarshalKey

func UnmarshalKey(key string, rawVal interface{}) error

UnmarshalKey populate struct from contents of cfg tree at key

func ValidateConfiguration

func ValidateConfiguration() error

ValidateConfiguration confirm the Configuration is valid

Types

type Config

type Config struct {
	LogLevel      string   `mapstructure:"logLevel"`
	Listen        string   `mapstructure:"listen"`

	AllowAllUsers bool     `mapstructure:"allowAllUsers"`
	PublicAccess  bool     `mapstructure:"publicAccess"`
	JWT           struct {
		MaxAge   int    `mapstructure:"maxAge"` // in minutes
		Issuer   string `mapstructure:"issuer"`
		Secret   string `mapstructure:"secret"`
		Compress bool   `mapstructure:"compress"`
	}

		AccessToken   string            `mapstructure:"accesstoken"`
		IDToken       string            `mapstructure:"idtoken"`
		ClaimsCleaned map[string]string // the rawClaim is mapped to the actual claims header
	}
	Session struct {
		Name string `mapstructure:"name"`
		Key  string `mapstructure:"key"`
	}
	TestURL            string   `mapstructure:"test_url"`
	TestURLs           []string `mapstructure:"test_urls"`
	Testing            bool     `mapstructure:"testing"`
	LogoutRedirectURLs []string `mapstructure:"post_logout_redirect_uris" envconfig:"post_logout_redirect_uris"`
}

Config vouch jwt cookie configuration Note to developers! Any new config elements should use `snake_case` such as `post_logout_redirect_uris` in certain situations you'll need to add both a `mapstructure` tag used by viper as well as a `envconfig` tag used by https://github.com/kelseyhightower/envconfig though most of the time envconfig will use the struct key's name: VOUCH_PORT VOUCH_JWT_MAXAGE

type OAuthProviders

type OAuthProviders struct {
	Google        string
	GitHub        string
	IndieAuth     string
	ADFS          string
	Azure         string
	OIDC          string
	HomeAssistant string
	OpenStax      string
	Nextcloud     string
}

OAuthProviders holds the stings for
