Deploy an Application

In this quickstart page, you’re going to deploy a sample application in a demo TSB environment and validate the success using the TSB UI, and tctl commands.

Before you get started make sure that you:

✓ Familiarize yourself with TSB concepts including workspaces and config groups
✓ Install the TSB demo

The TSB demo install will do everything for you, including onboarding a cluster and installing all the operators that you’ll need. It will also provide you with the URL and admin login information to access the TSB UI.

Deploying a Demo Application

You’re going to use the classic Istio bookinfo demo application to test TSB’s functionality. So make sure that you have the below YAML configuration saved as bookinfo.yaml. You can also download it from here.

Deploy bookinfo

Deploy the bookinfo application to your cluster using the following kubectl command:

kubectl apply -n bookinfo -f bookinfo.yaml

Confirm your services are running

To confirm all of your services and pods are running, validate with:

kubectl get pods -n bookinfo

Expected output:

NAME                             READY   STATUS    RESTARTS   AGE
details-v1-5bc5dccd95-2qx8b      2/2     Running   0          38m
productpage-v1-f56bc8d5c-42kcg   2/2     Running   0          38m
ratings-v1-68f58946ff-vcrdh      2/2     Running   0          38m
reviews-v1-5976d456d4-nltg2      2/2     Running   0          38m
reviews-v2-57cf5b5488-rgq8l      2/2     Running   0          38m
reviews-v3-7745dbf976-4gnl9      2/2     Running   0          38m

Make sure you can access the bookinfo application

Confirm that you can access the bookinfo application:

kubectl exec "$(kubectl get pod -n bookinfo -l app=ratings -o jsonpath='{.items[0].metadata.name}')"  \
    -n bookinfo -c ratings -- curl -s productpage:9080/productpage | \
    grep -o "<title>.*</title>"

You will see something similar to:

<title>Simple Bookstore App</title>

Verify that your application is onboarded into TSB

To confirm that your application is onboarded to TSB using the UI, navigate to the Services page by selecting the bottom button on the left side banner. You’ll see all your services running.

To use tctl, run

tctl get clusters demo -o yaml | grep bookinfo

You'll see the following:

- name: bookinfo
    - hostname: details.bookinfo.svc.cluster.local
      namespace: bookinfo
    - hostname: productpage.bookinfo.svc.cluster.local
      namespace: bookinfo
    - hostname: ratings.bookinfo.svc.cluster.local
      namespace: bookinfo
    - hostname: reviews.bookinfo.svc.cluster.local
      namespace: bookinfo
