我正在尝试设置 deepstream.io。我的目标是拥有一个 4 docker 容器:

• 深入研究
• 深度搜索
• redis
• 反射(reflection)

Redis 和 Rethink 正在运行并正在接受连接。现在启动 deepstream 表明缓存和存储还没有准备好。我不明白为什么以及“提供的依赖项描述”应该告诉我什么。

为什么 deepstream 不接受连接？

最佳答案

消息 no dependency description provided 只是意味着在引擎盖下，连接器没有 description 属性。

我建议尝试通过 deepstream 客户端设置一些数据，看看它是否被写入数据库。

关于redis - deepstream.io redis 和 rethink 还没有准备好，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47367224/
