ECK (kubernetes上的弹性云)，弹性版本6.8.8

Question

容器没有出现，它失败了，并出现了下面的错误。eck是否支持elastic 6.8.8？

原因: java.lang.IllegalArgumentException:未知设置discovery.seed_providers请检查是否安装了任何必需的插件，或查看中断更改文档以了解删除的设置

Answer 1

您使用的是哪个版本的ECK？它是全新的群集还是从现有群集升级？

我尝试用最小的6.8.8集群在本地复制，当运行ECK 1.0.1时，一切正常：

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: elasticsearch-sample
spec:
  version: 6.8.8
  nodeSets:
  - name: default
    count: 3
    config:
      node.store.allow_mmap: false

我注意到你显式地设置了Docker镜像。这通常不是必需的，除非您使用的是自定义Docker镜像或私有注册表。因此，我想知道是否有可能您正在使用自定义Docker镜像，而image和version的值在某一时刻并不一致？

更多的解释：discovery.seed_providers是一个只存在于7.0或更高版本的Elasticsearch的设置。所以我想知道您是否有可能在某个时候为6.8.8指定了Docker镜像，但是version属性是7.x？然后，操作员将尝试使用与7.x相关的设置，您可能会看到您发布的错误。
