Kuma Mesh - Policies

Prerequisites for using these Kuma Policies

• Kubernetes cluster - Build K8s cluster using Minikube https://minikube.sigs.k8s.io/docs/start/
• Install Kuma Mesh - https://kuma.io/docs/1.3.0/installation/kubernetes/

Getting Started

Explore below Kuma Mesh policies which can be applied for service to service communication within the mesh -

• MTLS
• Traffic permission
• Traffic route
• Rate limiting

Steps to implement the policies defined above

1. Deploy demo app and redis from https://github.com/kumahq/kuma-counter-demo
2. Once the pods are running then apply mtls.yaml to encrypt the traffic between services.

kubectl apply -f kuma-mesh-policies/policies/mtls.yaml

3. Apply traffic-permission.yaml to allow traffic to the authorized destination service.

kubectl apply -f kuma-mesh-policies/policies/traffic-permission.yaml

4. Create different version of redis and apply traffic-route.yaml for blue/green or canary deployments for redis services.

kubectl apply -f kuma-mesh-policies/deployment/kuma-demo-redis.yaml -n kuma-demo
kubectl apply -f kuma-mesh-policies/policies/traffic-route.yaml

5. Apply rate limiting policy to limit the traffic for destination service.

kubectl apply -f kuma-mesh-policies/policies/rate-limit.yaml
