Loki Configuration Examples
almost-zero-dependency.yaml
# This is a configuration to deploy Loki depending only on a storage solution
# for example, an S3-compatible API like MinIO.
# The ring configuration is based on the gossip memberlist and the index is shipped to storage
# via Single Store (boltdb-shipper)
