我正在尝试在我的Rackspace服务器上创建一个Bosh Microinstance，并收到以下错误：

"microbosh-openstack/bosh_micro_deploy.log" 215L, 28192C
我有一个.yml文件设置，出于安全原因我无法发布，但我已经通过我的IAAS支持验证我有正确的凭据。
有人在Openstack上看到过这样的错误吗？此外，我得到一个堆栈跟踪，一半试图尝试调试。问题是我不太熟悉调试这些大型开放项目。有没有人知道一个很好的资源解释如何开始调试它们？
答案 0 :(得分：2)
您看到的错误是由OpenStack拒绝您提供的凭据引起的。一个可能的缺陷：您使用Rackspace帐户密码代替“密码”而不是API密钥吗？您可以logging in to your account找到您的API密钥，点击右上角的用户名，然后从下拉列表中选择“帐户设置”。 （我假设你因为问题标签而使用Rackspace。）
您提到您已经与提供商进行了验证 - 也许他们没有正确传递？根据{{3}}，您应该将它们放在micro_bosh.yml文件中，格式如下：
# ...
cloud:
plugin: openstack
properties:
openstack:
auth_url: http://<identity_server>:5000/v2.0
username: <username>
api_key: <password>
tenant: <tenant>
region: <region> # Optional
default_security_groups: ["ssh", "bosh"]
default_key_name: <microbosh_keypair>
private_key: <path_to_microbosh_keypar_private_key>
# ...
请记住，YAML对空格敏感。
至于调试开源项目，我能给出的最佳指导是不要害怕来源并且要有耐心。 bosh的源代码可以在documentation上找到，因此您可以轻松地GitHub browse around对您的堆栈跟踪进行源代码编写，以尝试找出正在发生的事情。从您看到的实际异常或错误消息向后工作;尝试确定被置于意外状态的内容，并跟踪调用者以弄清楚它是如何以这种方式结束的。阅读其他人的源代码是一项非常有用的技能，通过练习变得更容易，所以有了它！
