Docker Compose Elastic Stack 与 xpack 安全 Kibana 不连接

Question

我正在使用 Docker Compose、Serilog、Elasticsearch、Kibana 和 Postgresql 编写 Asp.Net Core 6 Web API 项目。 我的 Github Repo我成功运行了所有依赖项，例如 Elastic、Kibana 等。但 Kibana 没有连接到弹性搜索。 Kibana 说：

{"type":"log","@timestamp":"2022-07-02T08:27:16Z","tags":["warning","elasticsearch","admin"],"pid":7,"message":"Unable to revive connection: http://elasticsearch:9200/"}

{"type":"log","@timestamp":"2022-07-02T08:27:16Z","tags":["warning","elasticsearch","admin"],"pid":7,"message":"No living connections"}

Kibana 没有连接到弹性搜索。 那个代码有什么问题？

Answer 1

我的错误是错误地写入 kibana 环境，例如

• ELASTICSEARCH_HOST=http://elastic_image:9200

正确的一个是

• ELASTICSEARCH_HOSTS=http://elastic_image:9200

我缺少“S”字符并且 Kibana 没有连接。
