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 one of the modes above and that a values.yaml
has been created.
To use a managed object store:
In the
values.yaml
file, set the value forstorage.type
toazure
,gcs
, ors3
.Configure the storage client under
loki.storage.azure
,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.
- If the Terraform module was used note the annotation emitted by
terraform output -raw annotation
.
- If the Terraform module was used note the annotation emitted by
Add the IAM role annotation to the service account in
values.yaml
:serviceAccount: annotations: "eks.amazonaws.com/role-arn": "arn:aws:iam::<account id>:role/<role name>"
Configure the storage:
loki: storage: type: "s3" s3: region: eu-central-1 bucketNames: chunks: <bucket name> ruler: <bucket name> admin: <bucket name>
