Code to deploy all necessary tools for the monitoring workshop.

1. A kubernetes cluster to deploy all elements. You can use one of the following local clusters:

   • Minikube
   • Install MacOS Docker-Desktop and configure Docker-Desktop Local Kubernetes Cluster (easiest way for MacOs Users)
   • Kind cluster

2. kubectl installed and pointing to local cluster context. Installation tutorial here.

3. Helm installed locally. Installation tutorial here.

To deploy stack use the following script:

./deploy_stack.sh

To delete all the stack use the following script:

./delete_stack.sh

Once deployed stack, web interfaces can be exposed via port-forward (mapping the pod application port to a local port), to access the service via localhost:port.

Note: This is the easiest way to expose a service locally. Another options to expose services involve using ingresses, Nodeport/LoadBalancer services, etc. More information about accesing apps in a cluster here.

1. Expose Prometheus port.

   # Get Prometheus Pod Name
   export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=server" -o jsonpath="{.items[0].metadata.name}")
   
   # Expose Prometheus port (9090) via port-forward
   kubectl --namespace default port-forward $POD_NAME 9090

2. Go to http://localhost:9090 in a web browser to access prometheus UI.

1. Get grafana 'admin' password:

   kubectl get secret --namespace default grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

2. Expose Grafana port.

   # Get Grafana Pod Name
   export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=grafana" -o jsonpath="{.items[0].metadata.name}")
   
   # Expose Grafana port (3000) via port-forward
   kubectl --namespace default port-forward $POD_NAME 3000

3. Go to http://localhost:3000 in a web browser to access grafana UI. Access using 'admin' and password from step 1.

1. Expose angular-app port.

   # Get angular-app Pod Name
   export POD_NAME=$(kubectl get pods --namespace default -l "app=angular-app" -o jsonpath="{.items[0].metadata.name}")
   
   # Expose angular-app port (80) via port-forward to local port 8080
   kubectl --namespace default port-forward $POD_NAME 8080:80

2. Go to http://localhost:8080 in a web browser to access angular-app UI.
