Prerequisites¶

Author: KubeElasti Authors

Kubernetes Cluster: You should have a running Kubernetes cluster. You can use any cloud-based or on-premises Kubernetes distribution.
kubectl: Installed and configured to interact with your Kubernetes cluster.
Helm: Installed for managing Kubernetes applications.
Prometheus: You should have a prometheus installed in your cluster.

Installing Prometheus

We will setup a sample prometheus to read metrics from the ingress controller.

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack \
  --namespace monitoring \
  --create-namespace \
  --set alertmanager.enabled=false \
  --set grafana.enabled=false \
  --set prometheus.prometheusSpec.serviceMonitorSelectorNilUsesHelmValues=false

Ingress / Gateway: Install one edge integration so traffic reaches the resolver with the correct routing header. See Gateway and ingress integrations:
KEDA: [Optional] You can have a KEDA installed in your cluster, else HPA can be used.

Installing KEDA

We will setup a sample KEDA to scale the target deployment.

helm repo add kedacore https://kedacore.github.io/charts
helm repo update
helm upgrade --install keda kedacore/keda --namespace keda --create-namespace --wait --timeout 180s
