Configure storage
The scalable installation requires a managed object store such as AWS S3 or Google Cloud Storage or a self-hosted store such as Minio. The single binary installation can only use the filesystem for storage.
This guide assumes Loki will be installed in on of the modes above and that a values.yaml
has been created.
To use a managed object store:
Set the
type
ofstorage
invalues.yaml
togcs
ors3
.Configure the storage client under
loki.storage.gcs
orloki.storage.s3
.
To install Minio alongside Loki:
Change the configuration in
values.yaml
:- Enable Minio
minio: enabled: true
To grant access to S3 via an IAM role without providing credentials:
Provision an IAM role, policy and S3 bucket as described in Storage.
