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 ¶

	MetricsPort = 16000 + iota // XXX Used in ms/metrics/service.go.
	ExampleMetricsPort
)
