Michal Vaško, a DevOps engineer at cloudWerkstatt, discusses customizing Loki deployments using Ansible, emphasizing the flexibility and control it offers for log management. With the release of Loki 3.0, users can choose from various deployment methods like Helm, Tanka, Docker, or Ansible's Loki Role, which supports Debian, Ubuntu, and Red Hat. Vaško details both default and customized configurations, highlighting features such as filesystem storage and alerting rules tailored to specific needs. The process involves setting up an Ansible controller, installing the Grafana collection, and creating playbooks for deployment. Once deployed, logs can be sent to Loki via Grafana Alloy or Promtail and explored through Grafana after configuring the Loki data source. The Ansible role is idempotent, allowing easy deployment and removal with specific tags. For those overwhelmed by managing Loki, Grafana Cloud is suggested as an alternative for seamless log management.
