Functions

func AddConfigPath 

func AddConfigPath(in string)

AddConfigPath adds a path for Viper to search for the config file in. Can be called multiple times to define multiple search paths.

func AddRemoteProvider 

func AddRemoteProvider(provider, endpoint, path string) error

AddRemoteProvider adds a remote configuration source. Remote Providers are searched in the order they are added. provider is a string value: "etcd", "etcd3", "consul", "firestore" or "nats" are currently supported. endpoint is the url. etcd requires http://ip:port, consul requires ip:port, nats requires nats://ip:port path is the path in the k/v store to retrieve configuration To retrieve a config file called myapp.json from /configs/myapp.json you should set path to /configs and set config name (SetConfigName()) to "myapp".

func AddSecureRemoteProvider 

func AddSecureRemoteProvider(provider, endpoint, path, secretkeyring string) error

AddSecureRemoteProvider adds a remote configuration source. Secure Remote Providers are searched in the order they are added. provider is a string value: "etcd", "etcd3", "consul", "firestore" or "nats" are currently supported. endpoint is the url. etcd requires http://ip:port consul requires ip:port secretkeyring is the filepath to your openpgp secret keyring. e.g. /etc/secrets/myring.gpg path is the path in the k/v store to retrieve configuration To retrieve a config file called myapp.json from /configs/myapp.json you should set path to /configs and set config name (SetConfigName()) to "myapp". Secure Remote Providers are implemented with github.com/sagikazarmark/crypt.

SetTypeByDefaultValue enables or disables the inference of a key value's type when the Get function is used based upon a key's default value as opposed to the value returned based on the normal fetch logic.

For example, if a key has a default value of []string{} and the same key is set via an environment variable to "a b c", a call to the Get function would return a string slice for the key if the key's type is inferred by the default value and the Get function would return: 

[]string {"a", "b", "c"}

Otherwise the Get function would return: 

"a b c"

type Viper 

type Viper struct {

Viper is a prioritized configuration registry. It maintains a set of configuration sources, fetches values to populate those, and provides them according to the source's priority. The priority of the sources is the following: 1. overrides 2. flags 3. env. variables 4. config file 5. key/value store 6. defaults

For example, if values from the following sources were loaded: 

Defaults : {
	"secret": "",
	"user": "default",
	"endpoint": "https://localhost"
}
Config : {
	"user": "root"
	"secret": "defaultsecret"
}
Env : {
	"secret": "somesecretkey"
}

The resulting config will have the following values: 

{
	"secret": "somesecretkey",
	"user": "root",
	"endpoint": "https://localhost"
