uninitialized constant Faraday::Error::ConnectionFailed in elastic-search

Question

我正在按照本教程

在 rails 中实施弹性搜索

https://iridakos.com/programming/2017/12/03/elasticsearch-and-rails-tutorial

并将这些行添加到我的 User.rb include Elasticsearch::Model include Elasticsearch::Model::Callbacks & 还安装了这两个 gem gem 'elasticsearch-model' gem 'elasticsearch-rails' 但是当我尝试执行这个命令时 Post.import(force: true) 它给了我一个错误

uninitialized constant Faraday::Error::ConnectionFailed

Answer 1

是的最后我找到了我的案例的解决方案由于我的项目是一个 docker 化的项目并且我在本地运行ning 弹性搜索，这就是为什么我的应用程序没有与 elasticsearch 连接。

当我在我的 docker-compose.yml 中添加所有凭据后从中提取 docker 图像和运行 elasticsearch 时，我成功实现了它。

注意：您的 kibana 和 elasticsearch 版本应该相同。

我的docker-compose.yml
