Amazon ec2 测试厨房几乎每次传输文件都会失败

几乎每次我运行kitchen converge with ec2驱动程序时，它都能够创建服务器并建立ssh连接，但在检测到chef omnibus安装后，它尝试传输文件，但失败了，出现了一个毫无帮助的错误。我尝试过使用不同版本的netssh并重新安装chefdk。我已经让它在30次中成功地收敛了一次，但我不知道有什么不同

还有其他人遇到过这个问题吗

我也有类似的问题。经过大量挖掘，我在/var/log/secure中发现了一条有趣的消息-

“localhost sshd[1081]：错误：没有更多会话”

默认情况下，SSHD允许10个会话；这些未登录会话。如果由于某种原因，存在未正确关闭或打开的会话，您将收到此错误

然后我走进我的.厨房.yml并补充道：

max_ssh_sessions: 1

去运输科。所以现在看起来像：

transport:
  ssh_key: ./kitchen.pem
  # need to get this key from vault, then place it on the kitchen ecs container
  connection_timeout: 10
  connection_retries: 5
  max_ssh_sessions: 1
  username: centos

当我运行TestKitchen时，速度明显变慢了。然而，它在100%的时间都能工作。我认为正在发生的是，kitchen正在打开多个SSH会话，以加快所需工具的安装。例如，对于ansible/git/whatever，使用yum；对于chef，使用/tmp/install.sh

希望这对别人有帮助。我花了一点时间
