--- Managing Prometheus alerts in Kubernetes at scale using GitOps involves deploying the Prometheus Operator and managing alerts using a template-based approach. The Prometheus Operator provides Kubernetes-native deployment and management of Prometheus Alert Rules. A Helm template is used to parse alerts defined in each team's folder and create a PrometheusRule resource for each of them. This approach improves readability, scalability, and maintainability, making it easier to manage alerts as the organization grows. Additionally, this method allows for bulk changes to alerts, enabling teams to easily update labels, annotations, or severity values without manually editing individual files. By automating the process using GitOps tools like Helm and ArgoCD, teams can streamline their workflows, reduce errors, and improve overall efficiency.
