我如何解读 juju 包？例如，它是一个包含实例等的 wiki 包，以及带有 memcache 的 mysql 配置。charms deploy 没有建立任何关系，也没有公开任何服务。
一个人如何去读取 yaml 文件以便可以手动完成部署包并具有正确的关系等等？
在下面的这个例子中，我可以弄清楚其中的一些。问题是，amqp 从何而来？在第一部分中，我可以看到需要部署哪些 charms，并了解它们将出现在画布上的什么位置。
在关系部分，我可以看到 keystone 和 mysql 之间的关系。我没问题，直到我看到
“mysql：共享数据库”--“nova-cloud-controller：amqp”-“rabbitmq-server：amqp”
这个 amqp 是什么意思？我见过它在面向公众的 juju charms 网站上部署，但在我看来它不会在本地部署。任何有助于理解这一点的帮助都将不胜感激。

你可能会更幸运地破译一个比 openstack 更简单的魅力:)
amqp是关系名称，它使用参见此处的 metadata.yaml 文件rabbitmq中的接口进行通信：nova-cloud-controller
有关关系和接口的详细描述请参阅：
