Chef infra 厨师和刀子-在ec2上启动一个实例时，刀子挂在一个上面，有三个刀子作业

随机的，刀似乎挂着。我使用下面的命令启动了三个ami

两个会完成，一个会卡住。下面是挂刀作业的输出。所有这三只靴子在大约20%的时间里都能工作。刀有问题吗？我甚至试着在执行命令之间等待60秒，但都无济于事

由于某些原因，ssh demon的启动没有完成，或者刀子实例无法ssh到box。我经历过这两种情况对我的影响。你需要做一些工作来弄清楚这里发生了什么

第一步是确定ssh是否已启动并在机箱上运行。作为第一步，我将查看您的AWS控制台，并查看它为所讨论的实例显示了什么

我也会增加刀的冗长程度。我总是使用“-VV”选项来获得尽可能多的细节。

在我的情况下，这是由于ssh端口（22）在我的网络上被阻塞。也许下次再检查一下你是否在防火墙后面
