* cpu | string

  K8s cpu resource limit, e.g. "1" or "500m". Default is unset (no limit). This value is used
  for the "limits" portion of the resource requirements (the "requests" portion is
  automatically deduced from it).
  See https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
* ingestion-burst-size-mb | int

  Default: 15

  This config option matches exactly Loki's `ingestion_burst_size_mb`, except that it is an integer here
  (Loki takes a float).
  This same value is used internally for setting `per_stream_rate_limit_burst`. Loki uses a default of 6 for
  `ingestion_burst_size_mb`, but 15 for `per_stream_rate_limit_burst`. For this reason we use 15 as the default
  here.

  Ref: https://grafana.com/docs/loki/latest/configure/#limits\_config
* ingestion-rate-mb | int

  Default: 4

  Per-user ingestion rate limit (MB/s).
  This config option matches exactly Loki's `ingestion_rate_mb`, except that it is an integer here
  (Loki takes a float).
  This same value is used internally for setting `per_stream_rate_limit`. Loki uses a default of 3 for
  `ingestion_rate_mb`, but 4 for `per_stream_rate_limit`. For this reason we use 4 as the default here.

  Ref: https://grafana.com/docs/loki/latest/configure/#limits\_config
* memory | string

  K8s memory resource limit, e.g. "1Gi". Default is unset (no limit). This value is used
  for the "limits" portion of the resource requirements (the "requests" portion is
  automatically deduced from it).
  See https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
* reporting-enabled | boolean

  Default: True

  When disabled, Loki will be configured to not send anonymous usage statistics to stats.grafana.org.
  It is very helpful to the Grafana project, so please leave this enabled.

  When enabled, Loki will use its default values for analytics.

  Ref: https://grafana.com/docs/loki/latest/configure/#analytics
* retention-period | int

  Sets a global retention period, in days, for log streams in Loki.
  The minimum retention period is 1 day, and a value of 0 (default) means "infinity" (disables retention).
  Loki will not be cleaning up logs if duration is set to 0.
  This config maps directly to the loki `compactor.retention_enabled` configuration option, which is set to `false` when no retention period is defined.
  Specifying retention periods for individual streams is not currently supported.
