terraform-kubernetes-google-slo-generator

An extremely opinionated module, that deploys [omni-slo-generator][omni-slo-gnerator] based on Google's SLO generator into GKE.

Assumptions made

• Prometheus backend is a mimir cluster
  • Mimir is running in monitoring namespace and has a nginx pod mimir-nginx for proxying (as mimir helm chart does it)
  • This can be overridden variable prometheus-backend-url
• You want to keep the default policies as shown in slo-exporter's examples (1h, 12h, 7d, 28d)
• You are using ingress nginx controller (this is configurable)
• GKE cluster has workload identity enabled
• You are running prometheus operator (monitoring.coreos.com/v1 in your cluster)

Diagram

Note: Ingress is deployed optionally, if you want to run your job inside kubernetes, you don't need to expose it outside the cluster.

Usage

module "slo-generator" {
  source = "heureka/google-slo-generator/kubernetes"
  version = "2.0.3"

  gke-project     = "company-k8s"
  storage-project = "todo-app"
  namespace       = "todo-app"
  ingress-host    = "slo-generator.example.com"  # optional
  bucket-name     = "company-todo-app-slos"
}

After that, you can upload your SLO manifests to the SLOs bucket, which the generator will automatically go through and calculate SLOs for
