Question

几乎每次我运行厨房与ec2驱动程序融合时，它都能够创建服务器并建立一个ssh连接但是在检测到厨师综合安装之后它会尝试传输文件但是失败并且没有任何帮助。我尝试过使用不同版本的net-ssh并重新安装chefdk。我已经得到它成功收敛一次可能30次，并无法弄清楚有什么区别。

还有其他人遇到过这个问题吗？

我有类似的问题。经过大量挖掘后，我在 / var / log / secure 中找到了一条有趣的消息 -

“localhost sshd [1081]：错误：没有更多会话”。

默认情况下，SSHD允许10个会话;这些不会记录在会话中。如果由于某种原因导致会话未正确关闭或打开，您将收到此错误。

然后我进入了我的。 kitchen.yml 并添加了：

max_ssh_sessions: 1

到运输部门。所以它现在看起来像：

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

当我跑测试厨房时，它明显变慢了。但是，它100％的工作时间。我认为正在发生的是，厨房正在打开多个SSH会话，以加快所需工具的安装。例如yum为ansible / git / whatever和/tmp/install.sh为chef。

希望这有助于某人。我花了一点时间才发现。

测试厨房几乎每次都在传输文件时失败
