Functions

func BindEnv added in v0.15.7 

func BindEnv(optName string)

BindEnv binds the option name with an deterministic generated environment variable which s based on the given optName. If the same optName is bind more than 1 time, this function panics.

func BindEnvWithLegacyEnvFallback added in v0.15.7 

func BindEnvWithLegacyEnvFallback(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 GetTunnelModes added in v0.15.7 

func GetTunnelModes() string

GetTunnelModes returns the list of all tunnel modes

func InitConfig added in v0.15.7 

func InitConfig(programName, configName string) func()

InitConfig reads in config file and ENV variables if set.

func LogRegisteredOptions added in v0.15.7 

func LogRegisteredOptions(entry *logrus.Entry)

LogRegisteredOptions logs all options that where bind to viper.

func MergeConfig added in v0.15.7 

func MergeConfig(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 VerifyMonitorAggregationLevel added in v0.15.7 

func VerifyMonitorAggregationLevel(key, value string) error

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

func (opts *MapOptions) Set(value string) error

Set validates, if needed, the input value and adds it to the internal map, by splitting on '='.

func (*MapOptions) String added in v0.10.0 

func (opts *MapOptions) String() string

func (*MapOptions) Type added in v0.10.0 

func (opts *MapOptions) Type() string

Type returns a string name for this Option type

type MonitorAggregationLevel added in v0.15.7 

type MonitorAggregationLevel OptionSetting

MonitorAggregationLevel represents a level of aggregation for monitor events from the datapath. Low values represent no aggregation, that is, to increase the number of events emitted from the datapath; Higher values represent more aggregation, to minimize the number of events emitted from the datapath.

The MonitorAggregationLevel does not affect the Debug option in the daemon or endpoint, so debug notifications will continue uninhibited by this setting.

type NamedMapOptions added in v0.10.0 

type NamedMapOptions struct {
	MapOptions
	// contains filtered or unexported fields
}

NamedMapOptions is a MapOptions struct with a configuration name. This struct is useful to keep reference to the assigned field name in the internal configuration struct.

func NewNamedMapOptions added in v0.10.0 

func NewNamedMapOptions(name string, values *map[string]string, validator Validator) *NamedMapOptions

NewNamedMapOptions creates a reference to a new NamedMapOpts struct.

type Option 

type Option struct {
	// Define is the name of the #define used for BPF programs
	Define string
	// Description is a short human readable description
	Description string
	// Immutable marks an option which is read-only
	Immutable bool
	// Requires is a list of required options, such options will be
	// automatically enabled as required.
	Requires []string
	// Parse is called to parse the option. If not specified, defaults to
	// NormalizeBool().
	Parse ParseFunc
	// FormatFunc is called to format the value for an option. If not
	// specified, defaults to formatting 0 as "Disabled" and other values
	// as "Enabled".
	Format FormatFunc
	// Verify is called prior to applying the option
	Verify VerifyFunc
}

Option is the structure used to specify the semantics of a configurable boolean option

func (Option) RequiresOption 

func (o Option) RequiresOption(name string) bool

RequiresOption returns true if the option requires the specified option `name`.

func GetEndpointMutableOptionLibrary added in v0.15.7 

func GetEndpointMutableOptionLibrary() OptionLibrary

func (OptionLibrary) Define 

func (l OptionLibrary) Define(name string) string

func (OptionLibrary) Lookup 

func (l OptionLibrary) Lookup(name string) (string, *Option)

func (OptionLibrary) Validate 

func (l OptionLibrary) Validate(name string, value string) error

func (*OptionLibrary) ValidateConfigurationMap added in v0.15.7 

func (l *OptionLibrary) ValidateConfigurationMap(n models.ConfigurationMap) (OptionMap, error)

ValidateConfigurationMap validates a given configuration map based on the option library

type OptionMap 

type OptionMap map[string]OptionSetting

func (OptionMap) DeepCopy 

func (om OptionMap) DeepCopy() OptionMap

type OptionSetting added in v0.15.7 

type OptionSetting int

OptionSetting specifies the different choices each Option has. 

const (
	// MonitorAggregationLevelNone represents no aggregation in the
	// datapath; all packets will be monitored.
	MonitorAggregationLevelNone OptionSetting = 0

	// MonitorAggregationLevelLow represents aggregation of monitor events
	// to emit a maximum of one trace event per packet. Trace events when
	// packets are received are disabled.
	MonitorAggregationLevelLowest OptionSetting = 1

	// MonitorAggregationLevelLow is the same as
	// MonitorAggregationLevelLowest, but may aggregate additional traffic
	// in future.
	MonitorAggregationLevelLow OptionSetting = 2

	// MonitorAggregationLevelMedium represents aggregation of monitor
	// events to only emit notifications periodically for each connection
	// unless there is new information (eg, a TCP connection is closed).
	MonitorAggregationLevelMedium OptionSetting = 3

	// MonitorAggregationLevelMax is the maximum level of aggregation
	// currently supported.
	MonitorAggregationLevelMax OptionSetting = 4
)
const (
	OptionDisabled OptionSetting = iota
	OptionEnabled
)

func NormalizeBool 

func NormalizeBool(value string) (OptionSetting, error)

func ParseDaemonOption added in v0.15.7 

func ParseDaemonOption(opt string) (string, OptionSetting, error)

ParseDaemonOption parses a string as daemon option

func ParseKeyValue added in v0.15.7 

func ParseKeyValue(lib *OptionLibrary, arg, value string) (string, OptionSetting, error)

func ParseMonitorAggregationLevel added in v0.15.7 

func ParseMonitorAggregationLevel(value string) (OptionSetting, error)

type ParseFunc added in v0.15.7 

type ParseFunc func(value string) (OptionSetting, error)

ParseFunc parses the option value and may return an error if the option cannot be parsed or applied.

type Validator added in v0.10.0 

type Validator func(val string) (string, error)

Validator returns a validated string along with a possible error.

type VerifyFunc 

type VerifyFunc func(key string, value string) error

VerifyFunc validates option key with value and may return an error if the option should not be applied
