在CircleCI中设置Elasticsearch和Ruby on Rails

I am trying to setup CircleCI with Elasticsearch in my Rails application. I think have the image configured, but how do I connect to it in CI?

我试图在我的Rails应用程序中使用Elasticsearch设置CircleCI。我认为配置了图像，但如何在CI中连接它？

So far I have tried...

The official docker images from elastic come with x-pack preinstalled.

弹性的官方码头图像预装了x-pack。

https://www.elastic.co/guide/en/elasticsearch/reference/5.4/docker.html

That means that your elasticsearch instance is running with security enabled, but you do not appear to be providing any security credentials to your elasticsearch client, and so you get an unauthorised (401) error when you try to connect.

这意味着您的elasticsearch实例在启用安全性的情况下运行，但您似乎没有向elasticsearch客户端提供任何安全凭据，因此当您尝试连接时会出现未经授权的（401）错误。

You should either turn off security in your ES instance by adding xpack.security.enabled: false to your elasticsearch.yml, or provide valid credentials in your request.

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

从另一个答案提供：

development: &default
  host: 'http://localhost:9200/'
  transport_options:
    request:
      timeout: !!integer 300

test:
  <<: *default

staging:
  <<: *default

continous_integration:
  <<: *default
  xpack.security.enabled: false
