Create the Meshed Application

Using the YAML we just reviewed, apply the meshed application resources with kubectl.

kubectl apply -f 2_meshed_application/meshed_app.yaml


namespace/prod configured
mesh.appmesh.k8s.aws/dj-app created
virtualnode.appmesh.k8s.aws/dj created
virtualservice.appmesh.k8s.aws/jazz created
virtualservice.appmesh.k8s.aws/metal created
virtualrouter.appmesh.k8s.aws/jazz-router created
virtualrouter.appmesh.k8s.aws/metal-router created
virtualnode.appmesh.k8s.aws/jazz-v1 created
virtualnode.appmesh.k8s.aws/metal-v1 created
service/jazz created
service/metal created
namespace/prod configured

This creates the Kubernetes objects, and the App Mesh controller in turn creates resources within AWS App Mesh for you.

You can see that your mesh object was created using kubectl.

kubectl get meshes


NAME     ARN                                                  AGE
dj-app   arn:aws:appmesh:us-west-2:1234567890:mesh/dj-app   119s

You can also see that the mesh was created in App Mesh using the aws CLI.

aws appmesh list-meshes


{
   "meshes" : [
      {
         "arn" : "arn:aws:appmesh:us-west-2:1234567890:mesh/dj-app",
         "meshName" : "dj-app",
         "version" : 1,
         "meshOwner" : "1234567890",
         "createdAt" : "2020-06-18T10:01:21.411000-04:00",
         "resourceOwner" : "1234567890",
         "lastUpdatedAt" : "2020-06-18T10:01:21.411000-04:00"
      }
   ]
}

Examine the objects within the prod namespace and you will see your App Mesh resources along with your native Kubernetes objects.

 kubectl get all -n prod
