如何让 Vanity 连接到 Elasticache 实例

Question

我正在使用 Vanity gem 进行 A/B 测试，它在本地运行良好。

在我们的 EC2 实例上 rails 拒绝在启用 Vanity 时启动。

通过为我的本地 Redis 安装提供不正确的详细信息，我已经能够在本地重现该问题。

我已经尝试了几种设置排列，我希望可以工作的两个是；

staging:
  adapter: redis
  connection: redis://my-name.id.0001.use1.cache.amazonaws.com:6379/0

和

staging:
  adapter: redis
  connection: redis://my-name.id.0001.use1.cache.amazonaws.com:6379

当我登录到服务器时，我可以运行 redis-cli -h my-name.id.0001.use1.cache.amazonaws.com 并立即连接。

我很确定这应该有效，因为 this person 能够使用 Heroku 设置（它只使用我上面使用的外部 URL）

错误信息

这是我在部署服务器时收到的错误消息。 job_options.rb 是我的测试实验，它在开发中运行良好。

看起来这是 Vanity 2.0 中的回归，在发布修复程序之前，您可以将 Vanity 配置中的 connection 键替换为 url 键，例如：

staging:
  adapter: redis
  url: redis://my-name.id.0001.use1.cache.amazonaws.com:6379/0

这些密钥被传递到各个适配器并且 ruby Redis client 接受 url。
