This rrepo is DEPRECATED! Use https://github.com/spacetab-io/configuration-go instead.
Configuration module for microservices written on Go. Preserves corporate standards for services configuration.
Using go get
:
go get github.com/imdario/mergo
Using dep
:
dep ensure -add github.com/microparts/configuration-golang
Import in your configuration file
import (
"github.com/microparts/configuration-golang"
)
Some agreements:
- Configuration must be declared as struct and reveals yaml structure
- Default config folder:
./configuration
. If you need to override, pass your path inReadConfig
function - Default stage is
development
. To override, setSTAGE
env variable
Code example:
package main
import (
"github.com/microparts/configuration-golang"
"gopkg.in/yaml.v2"
"log"
)
// Your app config structure. This must be related to yaml config file structure. Everything that is not
// in this struct will be passed and will not be processed.
// Keep in mind that inheritance must be implemented with `struct{}`
type ConfigStruct struct {
Log struct {
Level string `yaml:"level"`
Debug bool `yaml:"debug"`
Format string `yaml:"yaml"`
} `yaml:"log"`
Database struct {
Host string `yaml:"host"`
Port string `yaml:"port"`
User string `yaml:"user"`
Pass string `yaml:"password"`
Name string `yaml:"name"`
SslMode string `yaml:"sslMode"`
Logs bool `yaml:"logs"`
MigrateOnStart bool `yaml:"migrateOnStart"`
MigrationPath string `yaml:"migrationsPath"`
} `yaml:"db"`
Http struct {
Host string `yaml:"host"`
Port string `yaml:"port"`
} `yaml:"ws"`
}
func main() {
// Reader accept config path as param. Commonly it stored like STAGE in ENV.
configPath := config.GetEnv("CONFIG_PATH", "./configuration")
// Reading ALL config files in defaults configuration folder and recursively merge them with STAGE configs
configBytes, err := config.ReadConfigs(configPath)
if err != nil {
log.Fatalf("config reading error: %+v", err)
}
var Config ConfigStruct
// unmarshal config into Config structure
err = yaml.Unmarshal(configBytes, &Config)
if err != nil {
log.Fatalf("config unmarshal error: %+v", err)
}
}
