解决办法:

调整Loki配置参数

我们需要将replication_factor: 1设置为1

apiVersion: v1
kind: ConfigMap
metadata:
  name: loki
  namespace: middleware
  labels:
    app: loki
data:
  loki.yaml: |
    auth_enabled: false
    ingester:
      chunk_idle_period: 3m      # 如果块没有达到最大的块大小，那么在刷新之前，块应该在内存中不更新多长时间
      chunk_block_size: 262144
      chunk_retain_period: 1m      # 块刷新后应该在内存中保留多长时间
      max_transfer_retries: 0      # Number of times to try and transfer chunks when leaving before falling back to flushing to the store. Zero = no transfers are done.
      max_chunk_age: 20m            #一个timeseries块在内存中的最大持续时间。如果timeseries运行的时间超过此时间，则当前块将刷新到存储并创建一个新块
      lifecycler:       #配置ingester的生命周期，以及在哪里注册以进行发现
        ring:
          kvstore:
            store: inmemory      # 用于ring的后端存储，支持consul、etcd、inmemory
          replication_factor: 1      # 写入和读取的ingesters数量，至少为1（为了冗余和弹性，默认情况下为3）

replication_factor设置为3或者其它数值，则必须至少运行3个实例。并且环中必须至少有2个副本处于活动状态。
