# Thanos Helm Values
|
|
# Chart: https://github.com/bitnami/charts/tree/main/bitnami/thanos
|
|
#
|
|
# Architecture:
|
|
# - Prometheus (prometheus namespace) + Sidecar → uploads to MinIO
|
|
# - Query: queries Sidecar + Store Gateway, deduplicates data
|
|
# - Store Gateway: reads historical data from MinIO
|
|
# - Compactor: compacts and downsamples data in MinIO
|
|
|
|
# Object storage configuration (MinIO S3)
|
|
# Uses secret created by ExternalSecret
