Functions

func Flatten

func Flatten(i interface{}) []string

Flatten performs a depth-first serialization of a struct to a slice of strings. Each string will be formatted at 'path.to.leaf = value'.

}

FileLedger contains configuration for the file-based ledger.

type General

type General struct {
	ListenAddress     string

	BootstrapMethod   string
	BootstrapFile     string
	Profile           Profile
	LocalMSPDir       string
	LocalMSPID        string
	BCCSP             *bccsp.FactoryOpts
	Authentication    Authentication
}

General contains config which should be common among all orderer types.

type Kafka

type Kafka struct {
	Retry     Retry
	Verbose   bool
	Version   sarama.KafkaVersion // TODO Move this to global config
	TLS       TLS
	SASLPlain SASLPlain
	Topic     Topic
}

Kafka contains configuration for the Kafka-based orderer.

type Keepalive

type Keepalive struct {
	ServerMinInterval time.Duration
	ServerInterval    time.Duration
	ServerTimeout     time.Duration
}

Keepalive contains configuration for gRPC servers.

type Metadata

	RetryMax     int
	RetryBackoff time.Duration
}

Metadata contains configuration for the metadata requests to the Kafka cluster.

type Metrics struct {
	Provider string
	Statsd   Statsd
}

Operations confiures the metrics provider for the orderer.

type NetworkTimeouts

type NetworkTimeouts struct {
	DialTimeout  time.Duration
	ReadTimeout  time.Duration
	WriteTimeout time.Duration
}

NetworkTimeouts contains the socket timeouts for network requests to the Kafka cluster.

type Operations added in v1.4.0

type Operations struct {
	ListenAddress string
	TLS           TLS
}

Operations configures the operations endpont for the orderer.

type Producer

type Producer struct {
	RetryMax     int
	RetryBackoff time.Duration
}

Producer contains configuration for the producer's retries when failing to post a message to a Kafka partition.

type Profile

type Profile struct {

}

TopLevel directly corresponds to the orderer config YAML. Note, for non 1-1 mappings, you may append something like `mapstructure:"weirdFoRMat"` to modify the default mapping, see the "Unmarshal" section of https://github.com/spf13/viper for more info.

func Load

func Load() (*TopLevel, error)

Load parses the orderer YAML file and environment, producing a struct suitable for config use, returning error on failure.

type Topic added in v1.3.0

type Topic struct {
