Sample configuration for micro sized cluster with NGINX Ingress controller (micro, no HA)

# Example ITRS Analytics configuration for micro-sized instance handling 10k entities, 200k time series, 3k metrics/sec,
# no HA and with nginx Ingress controller.
#
# The resource requests total ~11 cores and ~50GiB memory and does not include optional Linkerd resources.
#
# It is recommended to use a storage class with defaults of 3000 IOPS and 125 MiB/s throughput.
# However, for higher-volume installations (i.e. more time series) it is recommended to use a storage
# class with increased IOPS for the Timescale workload (see below).
#
# Disk requirements for 7 days approximately, depending on the amount and type of data being ingested:
# - Timescale:
#   - 100 GiB data disk
#   - 40 GiB WAL disk
# - Kafka: 100 GiB
# - Kafka controller: 1 GiB
# - Postgres: 3 GiB
# - ClickHouse Keeper: 2 GiB
# - ClickHouse Traces: 30 GiB
# - Loki: 5 GiB
# - etcd: 1 GiB
# - Downsampled Metrics:
#   - Raw: 2 GiB
#   - Bucketed:  2 GiB
#
# Disk requirements for default retention approximately, depending on the amount and type of data being ingested:
# - Timescale:
#   - 500 GiB data disk
#   - 40 GiB WAL disk
# - Kafka: 100 GiB
# - Kafka controller: 1 GiB
# - Postgres: 3 GiB
# - ClickHouse Keeper: 2 GiB
# - ClickHouse Traces: 30 GiB
# - Loki: 10 GiB
