Dynatrace demo

This demo repository demonstrates Dynatrace used with Kubernetes

Setup

Prerequisites

Docker / k8s

You'll need Docker installed to use this demo. You'll also need to enable the built-in Kubernetes cluster.

Dynatrace

Create two environment variables for DYNATRACE_API_TOKEN and DYNATRACE_PAAS_TOKEN

Follow the docs to generate them:

• API Token
• PaaS Token

Install Project Dependencies

Run from the project root. This will install dependencies for each service.

npm install

Build docker images

There are several images that need to be built. Build them all by running:

sh build-images.sh

Apply Kubernetes Configuration

Apply the k8s configuration, replica scale can be modified for demonstration purposes. Configuration lives in deployment.yaml

sh deploy-kube.sh

Kubernetes Web UI

You can optionally set up the kubernetes web UI. The script will install it automatically, but you'll need to create a sample user and save the Bearer Token to login with. expose the web UI with:

kubectl proxy

It should now be available at http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

Cleaning up

This will remove all namespace, and associated pods, deployments, and ingresses

sh cleanup.sh

Development

Local development of the demo apps without kube or dynatrace monitoring

Setup

Install dependencies the same way from the project root

npm install

Dev Server

Docker/k8s is not required for the development server

npm run start:dev

This will start the React app in dev mode, and the server layers with a proxy for the React app. They should behave the same as their containerized counterparts.
