Golang client with TLS

The following code works for me:

func setupTLSConnection() (*grpc.ClientConn, error) {
	b, err := ioutil.ReadFile("tls/ca.crt")
	if err != nil {
		return nil, err
	}

	cp := x509.NewCertPool()
	if !cp.AppendCertsFromPEM(b) {
		return nil, errors.New("credentials: failed to append certificates")
	}

	cert, err := tls.LoadX509KeyPair("tls/client.acl.crt", "tls/client.acl.key")
	if err != nil {
		return nil, err
	}

	config := &tls.Config{
		InsecureSkipVerify: false,
		RootCAs:            cp,
		Certificates:       []tls.Certificate{cert},
	}
	conn, err := grpc.Dial("localhost:9180", grpc.WithTransportCredentials(credentials.NewTLS(config)))
	if err != nil {
		return nil, err
	}

	return conn, nil
}

Let me know if you have any more questions.
