Codespaces#

GitHub Codespaces gives you a fully configured cloud development environment — Kind cluster, Arc Store, and all tooling pre-installed — without any local setup.

1. Launch Codespace#

Click the badge below to open a new Codespace from the main branch:

Open in GitHub Codespaces

2. Codespace Configuration#

Machine sizing & secrets

Machine type

Select 4-core for enough resources to run the Kind cluster and all Arc Store services.

Secrets — enter your credentials in the following Codespace secrets before launching:

Secret Description
DT_ENVIRONMENT_ID Your Dynatrace environment ID, e.g. abc12345 from https://abc12345.live.dynatrace.com
DT_ENVIRONMENT_TYPE Your environment type: live, sprint, or dev. If unsure, use live.
DT_API_TOKEN Dynatrace Operator token — used to manage Dynatrace components in the Kubernetes cluster
DT_DATA_INGEST_TOKEN Dynatrace data ingest token — used to send logs, metrics, and traces

3. What Gets Deployed#

Once the Codespace finishes initialising, the following is ready for you:

  • A local Kind Kubernetes cluster
  • The Arc Store frontend, backend, and load generator — deployed to the arc-store namespace
  • The Dynatrace OneAgent

The load generator starts automatically and produces continuous traffic against the Arc Store, which will eventually trigger an error calling the tax service.

4. Troubleshooting#

Exposing the Arc Frontend locally#

Make sure to run:

nohup kubectl port-forward svc/arc-frontend 3000:80 -n arc-store > /tmp/arc-frontend-port-forward.log 2>&1 &

Cluster health#

Confirm the Kind cluster is running:

kubectl cluster-info

Pod status#

Check that all Arc Store services are up:

kubectl get pods -n arc-store

All pods should show Running. If any are in CrashLoopBackOff or Pending, check the logs:

kubectl logs -f deployment/<pod-name> -n arc-store
