Instana Agent Install

With the new release of Kubernetes support for Instana, the agent install is now available as a helm chart. This is the easiest way to install the agent, however if you really want to do it by hand, template descriptors are available in the official documentation.

Quotas and Scaling

You can apply resource quotas to the namespace where you installed Stan's Robot Shop.

$ kubectl -n robot-shop apply -f resource-quota.yaml

The quotas and usage are shown in the Instana Kubernetes dashboards.

Optinally you can also run the autoscale.sh script to configure automatic scaling of the deployments. You will need to edit the script if you did not deploy to the robot-shop namespace. Varying the load on the application will cause Kubernetes to scale up/down the various deployments.

Istio

Stan's Robot Shop will run on Kubernetes with Istio service mesh. Configure Istio ingress.

$ kubectl -n robot-shop apply -f Istio/gateway.yaml

Now use the exposed Istio gateway to access Robot Shop.

$ kubectl -n istio-system get svc istio-ingressgateway

The above will display the IP address of the Istio gateway.

NOTE The Instana agent only works with later versions of Istio.
