  1. Go to Alert sources --> Alert sources and click on Create new alert source

  2. Search for Kubernetes in the search field, click on the Kubernetes tile and click on Next.

  3. Give your alert source a name, optionally assign teams and click Next.

  4. Select an escalation policy by creating a new one or assigning an existing one.

  5. Select you Alert grouping preference and click Continue setup. You may click Do not group alerts for now and change it later.

  6. The next page show additional settings such as customer alert templates or notification prioritiy. Click on Finish setup for now.

In Kubernetes

a. Deploy ilert-kube-agent with helm (recommended)

  1. Add helm charts repo and update it
helm repo add ilert https://ilert.github.io/charts/
helm repo update
  1. Deploy ilert-kube-agent with the API Key that you generated in ilert
helm upgrade --install --namespace kube-system \
    ilert-kube-agent ilert/ilert-kube-agent \
    --set config.settings.apiKey="<YOUR KEY HERE>"

b. Deploy ilert-kube-agent with terraform (recommended)

  1. Define module and paste the API Key that you generated in ilert
module "ilert-kube-agent" {
  source  = "iLert/ilert-kube-agent/kubernetes"
  version = "0.3.9"
  replicas = 2
  api_key = "<YOUR KEY HERE>"
}
  1. Apply changes
terraform init
terraform apply

c. Deploy ilert-kube-agent with manifest

  1. Clone the ilert-kube-agent repository
git clone https://github.com/iLert/ilert-kube-agent.git
  1. Paste the API Key that you generated in ilert into ./example/standard/30-deployment.yaml

          env:
            ...
            - name: ILERT_API_KEY
              value: "<YOUR KEY HERE>"
...
  1. Apply the deployment manifest to your kubernetes cluster
kubectl apply -f deployment/standard/
  1. Verify that the ilert-kube-agent pods are running and ready
kubectl --namespace kube-system get pod -l app=ilert-kube-agent

NAME                               READY   STATUS    RESTARTS   AGE
ilert-kube-agent-64f7dfd4d-nsnzp   1/1     Running   0          37h
ilert-kube-agent-64f7dfd4d-zx7fb   1/1     Running   0          37h
