在流浪者条款上从私有 git 克隆？

Question

我想在配置基于 Linux 的 Vagrant 框时从 bitbucket 中的私有项目中检索项目，但我正在运行此操作失败。

操作的形式为：

cd /tmp

git clone ssh://git@bitbucket.org/myuser/myproject.git

在我的 Vagrant 文件中，我指定了：

 config.ssh.forward_agent = true

操作的输出是：

==> default: Cloning into 'myproject'...
==> default: Host key verification failed.
==> default: fatal: Could not read from remote repository.
==> default: 
==> default: Please make sure you have the correct access rights
==> default: and the repository exists.

如果我vagrant ssh进入盒子然后尝试相同的 git clone 我在克隆存储库时没有问题。

我尝试添加以下内容（其中“ubuntu”是框“ubuntu/xenial64”的默认用户）：

sudo -H -u ubuntu ssh-keygen -R bitbucket.org
sudo -H -u ubuntu git clone ssh://git@bitbucket.org/myuser/myproject.git

这只会导致：

==> default: Host bitbucket.org not found in /home/ubuntu/.ssh/known_hosts
==> default: Cloning into 'myproject'...
==> default: Host key verification failed.
==> default: fatal: Could not read from remote repository.
==> default: 
==> default: Please make sure you have the correct access rights
==> default: and the repository exists.

我还尝试将以下内容添加到脚本中，但没有任何变化：

ssh-keyscan -H bitbucket.com >> ~/.ssh/known_hosts
sudo -H -u ubuntu ssh-keyscan -H bitbucket.com >> ~/.ssh/known_hosts

流浪者配置：

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box = "ubuntu/xenial64"

  config.vm.synced_folder './', '/vagrant', disabled: false, create: true

  config.ssh.forward_agent = true

  config.vm.provider :virtualbox do |vb, override|
    vb.name = 'myproject-dev-standalone'    

    # Web server HTTP front end
    override.vm.network :forwarded_port, guest: 80, host: 10080
    # Web server HTTPS front end    
    override.vm.network :forwarded_port, guest: 443, host: 10443

    override.vm.provision :shell do |s|
      s.path = "provision/install.sh"
      s.privileged = false
    end
  end

end

任何人都可以建议git clone在配置期间无需将密码硬编码到安装脚本中的方法吗？
