为了确保容器的健康检查，我需要对多个 URL 执行测试调用。

curl -f http://example.com和curl -f http://example2.com

是否可以执行多个curl 调用来进行docker 健康检查？

我对 swift 和 IOS 非常陌生，我想以编程方式将两个标签并排水平居中放置。下面是我的代码

let secondLabel : UILabel = {
    let label = UILabel()
    label.text = "1234"
    label.textAlignment = .center
    label.translatesAutoresizingMaskIntoConstraints = false
    label.backgroundColor = UIColor.blue
    return label
}()

let thirdLabel : UILabel = {
    let label = UILabel()
    label.text = "5678"
    label.textAlignment = .center
    label.translatesAutoresizingMaskIntoConstraints = false
    label.backgroundColor = UIColor.red
    return label
}()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.

    setupLayout()
}

private func setupLayout(){
    view.addSubview(secondLabel)
    //secondLabel.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    secondLabel.centerYAnchor.constraint(equalTo: …
