Golang Config Parser for Kubernetes Configmap with Toml

Usage

Defines a config struct

type Config struct {
    EnvConfig EnvConfig `mapstructure:"env"`
}
type EnvConfig struct {
    Env         string `validate:"required"`
    ServiceName string `mapstructure:"service_name" validate:"required"`
    ProjectID   string `mapstructure:"project_id" validate:"required"`
    LogLevel    string `mapstructure:"log_level" validate:"required"`
}

Create a configmap file manifests/configmap.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: test-configmap
  labels:
    app: test
data:
  config.toml: |-
    [env]
        env = "1"
        service_name = "2"
        project_id = "3"
        log_level = "4"

Initialize config from struct main.go

c, err := configmapper.Initialize(Config{})
if err != nil {
    panic(err) // error handling
}
config := c.(Config)
// use config
...

if run local, run golang with LOCAL=1

LOCAL=1 go run main.go
