我遇到了很多问题：
Loki：内部服务器错误。 500.rpc 错误：code = Unavailable desc = name resolver error：produced zero addresses
2. 分发服务器日志显示时间戳错误：

我不确定我做错了什么。 我尝试了值文件中所有可能的更改。
我怀疑 Loki 配置文件有问题。
注意：当我尝试使用默认值安装 Loki 和 promtail 时。yaml 文件可以正常工作，但我仍然可以看到错误。
原因：'进入无序'
对于 loki，我能够弄清楚这个问题。
在官方网站上的示例 Loki 配置中，它被称为 index_gateway，但在图表中被禁用。
从 configmap 中删除行并进行滚动重启并开始工作。
index_gateway_client:
server_address: dns:///{{ include "loki.indexGatewayFullname" . }}:9095
对于 promtail“timestamp”错误，我仍然没有得到任何信息。
