MeshGatewayInstance

MeshGatewayInstance is a Kubernetes-only resource for deploying Kong Mesh’s builtin gateway.

MeshGateway and MeshGatewayRoute allow specifying builtin gateway listener and route configuration but don’t handle deploying kuma-dp instances that listen and serve traffic.

Kuma offers MeshGatewayInstance to manage a Kubernetes Deployment and Service that together provide service capacity for the MeshGateway with the matching kuma.io/service tag.

If you’re not using the default Mesh, you’ll need to label the MeshGatewayInstance using kuma.io/mesh.

Consider the following example:

apiVersion: kuma.io/v1alpha1
kind: MeshGatewayInstance
metadata:
  name: edge-gateway
  namespace: default
  labels:
    kuma.io/mesh: default # only necessary if not using default Mesh
spec:
  replicas: 2
  serviceType: LoadBalancer
  tags:
    kuma.io/service: edge-gateway

Once a MeshGateway exists with kuma.io/service: edge-gateway, the control plane creates a new Deployment in the default namespace. This Deployment deploys 2 replicas of kuma-dp and corresponding builtin gateway Dataplane running with kuma.io/service: edge-gateway. The control plane also creates a new Service to send network traffic to the builtin Dataplane pods. The Service is of type LoadBalancer, and its ports are automatically adjusted to match the listeners on the corresponding MeshGateway.

Customization

Additional customization of the generated Service is possible via spec.serviceTemplate. For example, you can add annotations to the generated Service, and specify the loadBalancerIP:

spec:
  replicas: 1
  serviceType: LoadBalancer
  tags:
    kuma.io/service: edge-gateway
  resources:
    limits: ...
    requests: ...
  serviceTemplate:
    metadata:
      annotations:
        service.beta.kubernetes.io/aws-load-balancer-internal: "true"
        ...
    spec:
      loadBalancerIP: ...
