Run docker

• Run docker compose & check docker container.
• Stop other tools in the demo app using docker compose stop grafana prometheus jaeger opensearch

Validate

• Open URL: http://localhost:8080
• Load generator: docker compose logs load-generator --tail=50
• Verify logs: docker compose logs otel-collector --tail=100

Test failure scenario

Generate load using below command.

for i in {1..200}; do
  curl -s http://localhost:8080 > /dev/null
  sleep 0.2
done

Or use http://localhost:xxxxx (Find port using docker compose ps load-generator)

Enable failure flags using http://localhost:8080/feature
