This is a very simple test app to help GOV.UK developers familiarise themselves with the new Kubernetes-based hosting.
Navigate to the test app url on your browser and set the status parameter as the status response you want, e.g. ?status=200
The app is intended to run on the GOV.UK Kubernetes clusters, but it is also possible to run it locally.
docker build -t govuk-replatform-test-app .
docker run --rm -p3000:3000 -p9394:9394 govuk-replatform-test-app
You should then be able to browse the web app on http://localhost:3000/ and the Prometheus metrics on http://localhost:9394/metrics.
