弹性运行时安装失败（未定义方法“地址”用于 nil:NilClass）

Question

我正在尝试在 GCP（谷歌云平台）上安装 PCF（Pivotal Cloud Foundry）作为 POC 的一部分。

我一直按照docs 上的说明进行操作。不幸的是，我遇到了一个障碍，我的 Elastic Runtime 安装失败并出现以下错误。

Director task 224  Started preparing deployment > Preparing deployment. Done (00:00:02)

Task 224 error

For a more detailed error report, run: bosh task 224 --debug

弹性运行时版本：1.11.6-build.4

我尝试在调试模式下运行此任务，据我所知，syslog_forwarder 似乎是罪魁祸首。这是堆栈跟踪：

cloud_controller_api.yml.erb、cloud_controller_clock.yml.erb 和 cloud_controller_worker.yml.erb 重复相同的堆栈

我在互联网上搜索过，但找不到任何有用的信息，而且我们还没有与 Pivotal 签订任何支持合同，他们的工程师将无法提供帮助。

如果有人能指出我正确的方向，我将不胜感激。

我在发布此内容时正在下载1.11.7-build.5，并会在尝试后提供更新。

更新：与1.11.7-build.5 的结果完全相同。

Answer 1

显然，旧版本（准确地说是1.10.21）提供了更好的错误消息。

原来是在Pivotal Elastic Runtime -> Settings -> Databases中选择Internal Databases - MySQL and Postgres选项时出现这个错误。

我将我的选择更改为Internal Databases - MySQL，它修复了错误。
