Documentation

Overview

Package confkeys defines all the configuration key alias that configure all the bundled features of mortar. Mortar expects that a `config.yaml` or similar will be loaded as Configuration and exposed via `interfaces/cfg/Config` interface. Mortar will access embedded keys using a `.` (dot) notation.

Example:

Config.Get("mortar.name").String()

*******************************************************************************

Everything related to mortar itself must be under the ROOT key == "mortar"

*******************************************************************************

Expected configuration structure is a map, below is a complete example in the YAML format:

# Root key of everything related to mortar configuration
mortar:
	# Application/Project name
	# Type: string
	name: "Application Name"
	# Web server related configuration
	server:
		grpc:
			# gRPC API External port
			# Type: int
			port: 5380
		rest:
			# RESTful API External port
			# Type: int
			external:
				port: 5381
			# RESTful API Internal port
			# Type: int
			internal:
				port: 5382
	# Default Logger related configuration
	logger:
		# Set the default log level for mortar logger
		# Possible values:
		#		trace, debug, info, warn, error
		# Type: string
		level: debug
		static:
			# enables/disables adding a git commit SHA in every log entry
			# Type: bool
			git: true
			# enables/disables adding a hostname in every log entry
			# Type: bool
			host: false
			# enables/disables adding an application/project name in every log entry
			# Type: bool
			name: false
	# Metrics/Monitoring related configuration
	monitor:
		# sets the namespace/prefix of every metric. Depends on the Metrics implementation
		# Type: string
		prefix: "awesome"
		# allows to include static labels/tags to every published metric
		# Type: map[string]string
		tags:
			tag1: value1
			tag2: value2
			tag3: value3
	# Bundled handlers configuration
	handlers:
		config:
			# defines a list of keywords that once contained within the configuration key will obfuscate the value
			# Type: []string
			obfuscate:
				- "pass"
				- "auth"
				- "secret"
				- "login"
				- "user"
	# Interceptors/Extractors configuration
	middleware:
		# set the default log level of all the bundled middleware that writes to log
		# Possible values:
		# 	trace, debug, info, warn, error
		# Type: string
		logLevel: "trace"
		# list of headers to be extracted from Incoming gRPC and added to every log entry
		# Type: []string
		logHeaders:
			- "x-forwarded-for"
			- "special-header"
		trace:
			http:
				client:
					# include HTTP client request to trace info ?
					# Type: bool
					request: true
					# include HTTP client response to trace info ?
					# Type: bool
					response: true
			grpc:
				client:
					# include gRPC client request to trace info ?
					# Type: bool
					request: true
					# include gRPC client response to trace info ?
					# Type: bool
					response: true
				server:
					# include incoming gRPC request to trace info ?
					# Type: bool
					request: true
					# include a gRPC response of incoming request to trace info ?
					response: true
		copy:
			# list of header prefixes to copy/forward from Incoming gRPC context to outgoing Request context/headers
			# Type: []string
			headers:
				- "authorization"
