Overview

Package config provides configuration shared by microservices.

Default values can be obtained from various sources (constants, environment variables, etc.) and then overridden by flags.

As configuration is global you can get it only once for safety: you can call only one of Get… functions and call it just once.

Constants

const (
	MonoPort = 17000 + iota
	ExamplePort
	ExampleMetricsPort
	AuthPort
	AuthPortInt
	AuthMetricsPort
	AuthGRPCGWPort
)

Default ports.

const EnvPrefix = "MONO_"

EnvPrefix defines common prefix for environment variables.

Shared contains configurable values shared by microservices.

func Get

func Get() (*Shared, error)

Get updates config defaults (from env) and returns shared config.
