type Config struct { Port int `env:"PORT"` Secret string `env:"SECRET"` }
config := Config{} err := engine.EnvDecode(&config) if err != nil { // Handle error }
type AppConfig struct { AppName string `env:"APP_NAME"` AppEnv string `env:"APP_ENV"` } func main() { config := AppConfig{} if err := engine.EnvDecode(&config); err != nil { fmt.Fprintln(os.Stderr, err) os.Exit(1) } }In this example, the `EnvDecode` function is used to decode environment variables into the `AppConfig` struct. It will look for the `APP_NAME` and `APP_ENV` environment variables and populate the corresponding fields in the struct. Overall, the `github.com/docker/docker/engine` package library provides useful functions for working with Docker containers, images, and networks in Go.
