Functions

func BindEnv added in v0.15.7 

func BindEnv(vp *viper.Viper, optName string)

BindEnv binds the option name with a deterministic generated environment variable which is based on the given optName. If the same optName is bound more than once, this function panics.

func BindEnvWithLegacyEnvFallback added in v0.15.7 

func BindEnvWithLegacyEnvFallback(vp *viper.Viper, optName, legacyEnvName string)

BindEnvWithLegacyEnvFallback binds the given option name with either the same environment variable as BindEnv, if it's set, or with the given legacyEnvName.

The function is used to work around the viper.BindEnv limitation that only one environment variable can be bound for an option, and we need multiple environment variables due to backward compatibility reasons.

func EndpointStatusValues added in v0.15.7 

func EndpointStatusValues() []string

EndpointStatusValues returns all available EndpointStatus option values

func EndpointStatusValuesMap added in v0.15.7 

func EndpointStatusValuesMap() (values map[string]struct{})

EndpointStatusValuesMap returns all EndpointStatus option values as a map

func FormatMonitorAggregationLevel added in v0.15.7 

func FormatMonitorAggregationLevel(level OptionSetting) string

FormatMonitorAggregationLevel maps a MonitorAggregationLevel to a string.

func InitConfig added in v0.15.7 

func InitConfig(cmd *cobra.Command, programName, configName string, vp *viper.Viper) func()

InitConfig reads in config file and ENV variables if set.

func LogRegisteredOptions added in v0.15.7 

func LogRegisteredOptions(vp *viper.Viper, entry *logrus.Entry)

LogRegisteredOptions logs all options that where bound to viper.

func MergeConfig added in v0.15.7 

func MergeConfig(vp *viper.Viper, m map[string]interface{}) error

MergeConfig merges the given configuration map with viper's configuration.

func MightAutoDetectDevices added in v0.15.7 

func MightAutoDetectDevices() bool

MightAutoDetectDevices returns true if the device auto-detection might take place.

func ReadDirConfig added in v0.15.7 

func ReadDirConfig(dirName string) (map[string]interface{}, error)

ReadDirConfig reads the given directory and returns a map that maps the filename to the contents of that file.

func ReplaceDeprecatedFields added in v0.15.7 

func ReplaceDeprecatedFields(m map[string]interface{})

ReplaceDeprecatedFields replaces the deprecated options set with the new set of options that overwrite the deprecated ones. This function replaces the deprecated fields used by environment variables with a different name than the option they are setting. This also replaces the deprecated names used in the Kubernetes ConfigMap. Once we remove them from this function we also need to remove them from daemon_main.go and warn users about the old environment variable nor the option in the configuration map have any effect.

func StoreViperInFile added in v0.15.7 

func StoreViperInFile(dir string) error

StoreViperInFile stores viper's configuration in a the given directory under the file name 'viper-config.yaml'. If this file already exists, it is renamed to 'viper-config-1.yaml', if 'viper-config-1.yaml' also exists, 'viper-config-1.yaml' is renamed to 'viper-config-2.yaml'

func VerifyMonitorAggregationLevel added in v0.15.7 

func VerifyMonitorAggregationLevel(key, value string) error

VerifyMonitorAggregationLevel validates the specified key/value for a monitor aggregation level.
