[AIAB-04] Setup Online Boutique

To get the target application (Online Boutique), the load generator (Locust), and the telemetry provider (Prometheus) installed, you need to use the three Kubernetes manifests available in the kube folder of your cloned repo. The corresponding kubectl commands must be issued from any terminal pointing to your cluster.

Notice: if you have installed the minikube cluster with the scripts provided in this guide, you can skip this command and proceed to the paragraph Install the target application.

Notice that all these three manifests refer to a label akamas/node=akamas to ensure that the corresponding pods are scheduled on the same node. For the sake of simplicity, run the following command to assign this label to the node you want to use for these pods (this is not needed for the Minikube cluster, which already is correctly configured):

kubectl label node <NODE> akamas/node=akamas

Install the target application

To install the Online Boutique application, you need to apply the boutique.yaml manifest to your cluster with the following command:

kubectl apply -f kubernetes-online-boutique/kube/boutique.yaml

This command will create the namespace akamas-demo and all the Deployment and Services of the Online Boutique inside that namespace. You can verify that all the pods are up and running with the command:

watch -d kubectl get pods -n akamas-demo

You can wait until the output is similar to the following one, then proceed:

Install the load generator

Then, to install Locust, you need to apply the loadgenerator.yaml manifest to your cluster:

kubectl apply -f kubernetes-online-boutique/kube/loadgenerator.yaml

You can verify that all the pods are up and running with the following command:

kubectl get pods -n akamas-demo -l app=ak-loadgenerator

The output should be similar to the following one:

ak-loadgenerator-5669ff6c96-nstcs           2/2     Running   0          10s

Install the telemetry provider

Finally, to install Prometheus, you need to apply the prometheus.yaml manifest:

kubectl apply -f kubernetes-online-boutique/kube/prometheus.yaml

You can verify that all the pods are up and running with the command:

kubectl get pods -n akamas-demo -l app=ak-prometheus

The output should be similar to the following one:

ak-prometheus-76b4b749b5-4g6wf                 1/1     Running   0          52s
