在CircleCI中设置Elasticsearch和Ruby on Rails

Question

我正在尝试在Rails应用程序中使用Elasticsearch设置CircleCI。我认为已配置了映像，但是如何在CI中连接到该映像？

到目前为止，我已经尝试过…

来自Elastic的官方Docker映像预装了x-pack。

https://www.elastic.co/guide/zh-
CN/elasticsearch/reference/5.4/docker.html

这意味着您的Elasticsearch实例在启用安全性的情况下运行，但是您似乎没有向Elasticsearch客户端提供任何安全凭证，因此401在尝试连接时会出现未授权（）错误。

您应该通过添加xpack.security.enabled: false来关闭ES实例中的安全性
elasticsearch.yml，或者在请求中提供有效的凭据。
