AWS CLI：无法在 Opsworks 上注册 EC2 EBS 支持的实例

Question

通过使用 AWS CLI，我尝试在指定的日期时间创建我的 OpsWorks 堆栈的克隆。

为了做到这一点，我确保我有以下内容：

• 我的 运行ning EBS 支持 OpsWorks 实例的每小时快照。
• 我的数据库的时间点 RDS 快照

与 RDS 相关的一切工作正常，但我似乎无法在 OpsWorks 中正确附加 EC2 实例。

起初，我尝试从我的快照创建一个 AMI，运行 它作为一个 EC2 实例，然后将它注册到我的堆栈中，这产生了以下错误：

[Thu, 12 Mar 2015 11:48:14 +0000] opsworks-init: Starting the installer Building native extensions. This could take a while... /tmp/opsworks-agent-installer.APUKk5gzWGKpIB4l/opsworks-agent-installer/opsworks-agent/lib/bootstrap/installer.rb:74:in install_instance_agent': /opt/aws/opsworks/releases/20150210181912_33600020150210181912 already exists and is current - aborting.

[Thu, 12 Mar 2015 11:50:08 +0000] opsworks-init: Please verify the log files found under /var/log/aws/opsworks and submit findings to AWS Support.

我的第二次尝试是用我的快照创建一个卷，然后用它替换我的 EC2 实例的根设备。结果是：

A client error (IncorrectState) occurred when calling the DetachVolume operation: Unable to detach root volume [...]

然后，我想我会使用 Amazon 的 Ubuntu LTS 14.04 AMI 测试附加一个新创建的 EC2 实例，但也没有成功:

似乎我 运行 在尝试在计算机上安装 OpsWorks 代理时遇到了一些问题。

使用 AWS CLI 在全新堆栈中注册 运行ning EBS 支持 Opsworks 堆栈的克隆的最佳方法是什么？

谢谢！

出于好奇，你在制作你的作品时是否遵循了the documentation on creating AMIs from OpsWorks instances？

在创建实例之前，您需要在实例上执行某些操作。我想它可能会干扰 opsworks init/bootstrap 进程。您遇到的错误似乎暗示了这一点。
