Wallarm

Wallarm Advaced Cloud-Native Web Applicaton Firewall

Wallarm

Wallarm is a DevOps-friendly Web Application Firewall (WAF) uniquely suited to protect your cloud applications and APIs. Wallarm installs natively in a Kubernetes environment.

Quick Start

Prerequisites

  1. Sign up for a Wallarm account.

  2. Add the Wallarm helm chart repository.

    helm repo add wallarm https://repo.wallarm.com/charts/stable
helm repo update

Install the Wallarm Ingress Controller (nginx + Wallarm WAF)

  1. In the Wallarm cloud console create a new node of type cloud.

  2. Copy the nodes token, since you will need that in the next step.

  3. Install the ingress controller.

    helm install wallarm/wallarm-ingress -n ingress-controller --set controller.wallarm.token=<CLOUD NODE TOKEN> --set controller.wallarm.enabled=true

Wallarm can be configured through helm values; you can find the options here.

Create an Ingress Route

  1. Create an ingress rule that exposes the http-echo-service.

    cat <<EOF | kubectl apply -f -
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-ingress
  annotations:
    kubernetes.io/ingress.class: nginx  
spec:
  rules:
    - http:
        paths:
          - path: /
            backend:
              serviceName: http-echo-service
              servicePort: 80

---
apiVersion: v1
kind: Service
metadata:
  name: http-echo-service
spec:
  ports:
    - port: 80
      targetPort: 5678
      name: web
  selector:
    app: http-echo

---
apiVersion: v1
kind: Pod
metadata:
  name: http-echo
  labels:
    app: http-echo
spec:
  containers:
    - name: http-echo
      image: hashicorp/http-echo
      args: ['-text="hello world"']
      ports:
        - containerPort: 5678
          name: web
EOF

  2. Enable traffic analysis for the ingress.

    kubectl annotate ingress nginx-ingress nginx.ingress.kubernetes.io/wallarm-mode=monitoring
kubectl annotate ingress nginx-ingress nginx.ingress.kubernetes.io/wallarm-instance=1

Delete the Ingress Controller

Delete the ingress controller.
