无法在 k8s 中设置 Elasticsearch 集群？

Question

我在托管在EKS节点组上的K8S上部署了一个Elasticsearch集群。k8s规范文件如下所示。

启动规范后，我可以看到有三个pod正在运行。

均显示master not discovered错误。有人知道我在说明中做错了什么吗?

Answer 1

仔细检查显示的错误:

…必须发现主节点[es-0.es-entrypoint.default.svc.cluster.local)……已发现[…]{es-0} {BDQHwbS2S06GIfbDZRqTzQ}…

发现的名称与所需的符合主资格的节点名称不匹配。
