我已经在本地集群中设置了 elastic + kibana + metricbeat。但 metricbeat 无法连接到弹性：

ERROR   pipeline/output.go:100  Failed to connect to

在我的集群中，我使用 metalldb 和 ingress。我已经设置了入口规则，但它没有帮助我。

另外我注意到 elk 和 metricbeat 在文档中有不同的命名空间。我试过在任何地方都使用相同的命名空间，但没有成功。

下面我附上了我的yamls。elastic/kibana 和 metricbeat 的文件我没有附上，因为它们有很多行，我只在它们上面写了 ref：

  1. 弹性/kibana - https://download.elastic.co/downloads/eck/1.0.0-beta1/all-in-one.yaml

  2. metricbeat - https://raw.githubusercontent.com/elastic/beats/7.4/deploy/kubernetes/metricbeat-kubernetes.yaml

也许有人知道为什么会这样？

只是要意识到。Filebeat、metricbeats... 在 kube-system 命名空间下运行。

如果您在默认命名空间上运行 elastic，您应该将elasticsearch.default 其用作主机以正确解析您的服务。
