Question

我已经在本地集群中设置了Elastic + Kibana + metricbeat。但是metricbeat无法连接到Elastic：

ERROR   pipeline/output.go:100  Failed to connect to 
backoff(elasticsearch(http://elasticsearch:9200)): Get http://elasticsearch:9200: lookup

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

我还注意到elk和metricbeat在文档中具有不同的命名空间。我尝试过在所有地方都使用相同的名称空间，但是没有成功。

在我下面附加了我的Yaml。我没有附加的elastic / kibana和metricbeat文件，因为它们有很多行，我只在它们上写了引用：

也许有人知道它为什么会发生吗？

请注意。 Filebeat，metricbeats ...在kube系统名称空间下运行。

如果您在默认名称空间上运行弹性，则应使用elasticsearch.default作为主机，以正确解析服务。

不能连接到Kubernetes（裸金属）中的Elasticsearch
