Show Me The Code!

Install Maesh (Helm Chart): Deploy Applications: Deploy SMI Objects to allow trafc in the mesh:

helm repo add maesh https://containous.github.io/maesh/charts helm repo update helm install --name=maesh --namespace=maesh maesh/maesh --values=./maesh/values.yaml kubectl apply -f apps/0-namespace.yaml kubectl apply -f apps/1-svc-accounts.yaml kubectl apply -f apps/2-apps-client.yaml kubectl apply -f apps/3-apps-servers.yaml kubectl apply -f apps/4-ingressroutes.yaml kubectl apply -f apps/5-smi-http-route-groups.yaml kubectl apply -f apps/6-smi-traffic-targets.yaml

A Closer Look To SMI Objects

apiVersion: specs.smi-spec.io/v1alpha1 kind: HTTPRouteGroup metadata: name: app-routes namespace: apps matches:

  • name: all

pathRegex: "/" methods: ["*"]

  • apiVersion: access.smi-spec.io/v1alpha1

kind: TrafficTarget metadata: name: client-apps namespace: apps destination: kind: ServiceAccount name: apps-server namespace: apps specs:

  • kind: HTTPRouteGroup

name: app-routes matches:

  • all
