Overview

Package config defines the full configuration structure used by the Benthos service, including methods of normalising and linting user configuration.

Functions

func AddExamples

func AddExamples(conf *Type, examples ...string)

AddExamples takes a configuration struct and a variant list of type names to add to it and injects those types appropriately.

For example, your variant arguments could be "kafka" and "amqp", which case this function will create a configuration that reads from Kafka and writes over AMQP.

func Lint

func Lint(rawBytes []byte, config Type) ([]string, error)

Lint attempts to report errors within a user config. Returns a slice of lint results.

func Read

func Read(path string, replaceEnvs bool, config *Type) ([]string, error)

Read will attempt to read a configuration file path into a structure. Returns an array of lint messages or an error.

Types

type SanitisedConfig

type SanitisedConfig struct {
	HTTP               interface{} `json:"http" yaml:"http"`
	Input              interface{} `json:"input" yaml:"input"`
	Buffer             interface{} `json:"buffer" yaml:"buffer"`
	Pipeline           interface{} `json:"pipeline" yaml:"pipeline"`
	Output             interface{} `json:"output" yaml:"output"`
	Manager            interface{} `json:"resources" yaml:"resources"`
	Logger             interface{} `json:"logger" yaml:"logger"`
	Metrics            interface{} `json:"metrics" yaml:"metrics"`
	Tracer             interface{} `json:"tracer" yaml:"tracer"`
	SystemCloseTimeout interface{} `json:"shutdown_timeout" yaml:"shutdown_timeout"`
}

SanitisedConfig is a config struct of generic types, this is returned by Sanitised() and is a generic structure containing only fields of relevance.

type Type

type Type struct {
	HTTP               api.Config `json:"http" yaml:"http"`
	stream.Config      `json:",inline" yaml:",inline"`
	Manager            manager.Config `json:"resources" yaml:"resources"`
	Logger             log.Config     `json:"logger" yaml:"logger"`
	Metrics            metrics.Config `json:"metrics" yaml:"metrics"`
	Tracer             tracer.Config  `json:"tracer" yaml:"tracer"`
	SystemCloseTimeout string         `json:"shutdown_timeout" yaml:"shutdown_timeout"`
}

Type is the Benthos service configuration struct.

func New

func New() Type

New returns a new configuration with default values.

func (Type) Sanitised

func (c Type) Sanitised() (*SanitisedConfig, error)

Sanitised returns a sanitised copy of the Benthos configuration, meaning fields of no consequence (unused inputs, outputs, processors etc) are excluded.
