Loki Ingester Configuration Unusable

Bug

Description

The values configuration for ingester says that we should be able to add our own ingester configuration for loki-write pods.

However... below it in the same config block the ingester keyword appears again, effectively blowing away any configuration above, per the yaml spec.

Replication:

Setting this in the bigbang values:

loki:
  values:
    loki:
      ingester:
        wal:
          replay_memory_ceiling: 1500MB

Results in a values file that looks identical to hardcoded block in the loki values file:

...
    ingester:
      chunk_target_size: 196608
      flush_check_period: 5s
      flush_op_timeout: 100m
      lifecycler:
        ring:
          kvstore:
            store: memberlist
          replication_factor: 1

BigBang Version
