func main() {
var (
host = getenv.String("HOST", "0.0.0.0")
ports = getenv.Ints("PORTS", []int{8080, 8081, 8082})
debug = getenv.Bool("DEBUG", false)
threshold = getenv.Float("THRESHOLD", 0.5)
maxBodySize = getenv.Int("MAX_BODY_SIZE", uint64(1<<20)) // 1MB
shutdownTimeout = getenv.Duration("SHUTDOWN_TIMEOUT", 5*time.Second)
whitelistHeaders = getenv.Strings("WHITELIST_HEADERS", []string{"Content-Type", "Content-Length"})
