OpenShift Container Platform

Create a LokiStack custom resource

Deploy the LokiStack custom resource using the web console or OpenShift CLI (oc), ensuring you configure the correct namespace, deployment size, and secret name for Loki object storage.

You can deploy a LokiStack custom resource (CR) to create a namespace or new project.

Procedure

Navigate to Ecosystem → Installed Operators, viewing All projects from the Project dropdown.
Look for Loki Operator. In the details, under Provided APIs, select LokiStack.
Click Create LokiStack.
Ensure the following fields are specified in either Form View or YAML view:
```
apiVersion: loki.grafana.com/v1
kind: LokiStack
metadata:
  name: loki
  namespace: netobserv-loki
spec:
  size: 1x.small
  storage:
    schemas:
    - version: v13
      effectiveDate: '2022-06-01'
    secret:
      name: loki-s3
      type: s3
  storageClassName: gp3
  tenants:
    mode: openshift-network
```
where:

metadata.namespace

Specifies the namespace for the LokiStack resource. While this example uses netobserv-loki, you can use a different namespace for different components.

spec.size

Specifies the deployment size. In Loki Operator 5.8 and later versions, the supported size options for production instances of Loki are 1x.extra-small, 1x.small, or 1x.medium.

It is not possible to change the number 1x for the deployment size.

spec.storageClassName

Specifies a storage class name that is available on the cluster for ReadWriteOnce access mode. For best performance, specify a storage class that allocates block storage. Use the oc get storageclasses command to see available storage classes on your cluster.

You must not reuse the same LokiStack custom resource that is used for logging.
Click Create.
