Loki

Loki is a horizontally scalable, highly available, multi-tenant log aggregation and storage system inspired by Prometheus. It doesn’t index the contents of logs, but rather a set of labels for each log stream.

1. Create a service account required to access Yandex Object Storage:

   yc iam service-account create --name <service account name>
   

2. Assign the storage.uploader and storage.viewer roles to the service account.

3. Create a static access key for the service account in JSON format and save it to the sa-key.json file:

   yc iam access-key create \
      --service-account-name=<service account name> \
      --format=json > sa-key.json
   

4. Create a bucket in Object Storage.

5. Configure the application:

   • Namespace: Select a namespace or create a new one.
   • Application name: Enter a name for the application.
   • Bucket name: Specify the name of the bucket in Object Storage.
   • Static access key: Paste the contents of the sa-key.json file.
   • Install Promtail: Leave the option enabled to deliver local logs to the Grafana Loki instance using the Promtail agent. This agent is usually used for applications that require regular monitoring.

6. Click Install.

7. Wait for the application to change its status to Deployed.

8. (Optional) Access the Loki gateway within the cluster at http://loki-gateway.<namespace>.svc.cluster.local.
