Basic Routing in Gloo Enterprise Console

This is a quick walk through guide on using the Gloo Enterprise Console. This guide will show you how to create a route rules (proxy) to a monolith application, and then re-directing a page request to a new microservice.

Route Rule to an Existing Application

This example will show creating route rules in Gloo to a “Lift and Shift” monolith application hosted in Kubernetes.

  1. Install example application into your Kubernetes cluster. This is the classic Spring PetClinic application that has been moved into a container.

    kubectl apply \
        --namespace default \
  2. Open the Gloo Enterprise console

    • The most consistent way to access the Gloo Enterprise Console deployed in any Kubernetes cluster is to use the kubectl port-forward command. The following command will give you access to the console in your local web browser at http://localhost:8088

      kubectl port-forward --namespace gloo-system deploy/api-server 8088:8088
    • If you’re running minikube, the quick way to open the Gloo Enterprise Console is the following command, which will automatically open the console in a browser window.

      minikube service --namespace gloo-system apiserver-ui

      You can use the --url option to see the url.

      minikube service --namespace gloo-system apiserver-ui --url
    • Otherwise, you can get your Kubernetes Cluster IP using kubectl cluster-info. In this example, my Cluster IP is; where the Kubernetes master is running.

      kubectl cluster-info
      Kubernetes master is running at
      KubeDNS is running at
      To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

      And the console port number using the following. In this example, the port number is 31242.

      kubectl get service --namespace gloo-system apiserver-ui
      NAME           TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
      apiserver-ui   NodePort   <none>        8088:31242/TCP   129m

      So to open the Gloo Enterprise Console, in this example, I’d open a browser to

  3. Your console should look something like the following.

    Basic Console

  4. Create a new Virtual Service.

    • Click on the Create Virtual Service + link in the upper right corner of the console.

    Create Virtual Service

    • In the New Virtual Service pop up, enter the following information.

      • Name: default
      • Add Domain: * and click on +
      • Namespace: gloo-system
      • Click Submit

    New Virtual Service

  5. Add a route by right clicking in the DEFAULT Virtual Service, and selecting New Route in the pop up.

    Add Route

    • In the New Route pop up, enter the following information.

      • Virtual Service: default
      • Path: /
      • Upstream Name: default-petclinic-8080
      • Click Submit

      New Route

  6. Test the route.

    • Get Gloo gateway url. The following command will return the base url for the Gloo Gateway proxy. Since we setup our route rules for / for the petclinic app, you can open your browser to the url returned by the following command.
    glooctl proxy url
    • You should see the petclinic app in your browser


Routing Rule to Redirect a Page Request in an Existing Application

In the petclinic application, if you click on the Veterinarians tab you will see a table with 2 columns. Let’s say that our team created a new microservice petclinic-vet that returns a new 3 column table with additional information our customers want. This example will show how to redirect a page (HTTP GET) request such that we can enhance the functionality of our application without needing to change the original monolithic petclinic application. This allows you to provide new functionality independent of efforts to change original code.

Petclinic Veterinarians

Let’s create a new route rule to redirect requests to /vets to our new microservice

  1. On the Catalog tab of the Gloo Enterprise Console, right click on the DEFAULT Virtual Service to add a new route.

    Add Route

    • In the New Route pop up, enter the following information.

      • Virtual Service: default
      • Path: /vets
      • Ensure Match type is set to PREFIX (default)
      • Upstream Name: default-petclinic-vets-8080
      • Click Submit

      New Route Vet

  2. On the Routes tab of the Console, on the default Virtual Service expand the routes, and re-order the routes so that /vets is first. That way the /vets path prefix will be matched before /.

    Reorder Routes

  3. Test the new route by refreshing the petclinic app, and clicking on the VETERINARIANS tab. If the redirect route rule is working correctly, you should now see 3 columns in the Veterinarians table.
