Now try below command to install promtail as daemonset, helm upgrade --install promtail loki/promtail --set "loki.serviceName=loki", While running above command may be you can get below error related to promtail has no deployed release. One of the main differences to conventional logging systems is that Loki indexes just the metadata rather than the logs whole contents. We mentioned earlier the monolithic and read-write separation modes of Loki deployment, and when your daily log size exceeds terabytes, then we may need to use the microservice mode to deploy Loki.. It must be deployed to your cluster and persistence must be enabled (allow Helm to create a Scaleway block device and attach it to the Loki pod to store its data) using a Kubernetes Persistent Volumes to survive a pod re-schedule: His analytical, organized, and people-oriented nature makes him an apt advisor on software projects and flexible staffing.
