Smoke Tests

Run these checks after allowing 5—10 minutes for cloud-init to complete.

Health Endpoint

ORIGIN_IP=$(terraform output -raw public_ip)

curl -sf "http://${ORIGIN_IP}/health" | jq .

Expected:

{
  "status": "healthy",
  "component": "origin-server",
  "applications": ["juice-shop", "dvwa", "vampi", "httpbin", "whoami", "csd-demo", "dvga", "restaurant", "crapi"]
}

Application Endpoints

# Default landing page
curl -sf "http://${ORIGIN_IP}/" -o /dev/null -w "Landing: %{http_code}\n"

# Juice Shop
curl -sf "http://${ORIGIN_IP}/juice-shop/" -o /dev/null -w "Juice Shop: %{http_code}\n"

# DVWA
curl -sf "http://${ORIGIN_IP}/dvwa/" -o /dev/null -w "DVWA: %{http_code}\n"

# VAmPI
curl -sf "http://${ORIGIN_IP}/vampi/" -o /dev/null -w "VAmPI: %{http_code}\n"

# httpbin
curl -sf "http://${ORIGIN_IP}/httpbin/get" -o /dev/null -w "httpbin: %{http_code}\n"

# whoami
curl -sf "http://${ORIGIN_IP}/whoami/" -o /dev/null -w "whoami: %{http_code}\n"

# DVGA
curl -sf "http://${ORIGIN_IP}/dvga/" -o /dev/null -w "DVGA: %{http_code}\n"

# RESTaurant
curl -sf "http://${ORIGIN_IP}/restaurant/docs" -o /dev/null -w "RESTaurant: %{http_code}\n"

# crAPI (port 8888)
curl -sf "http://${ORIGIN_IP}:8888" -o /dev/null -w "crAPI: %{http_code}\n"

All should return 200 (DVWA returns 302 redirect to login).

Automated Smoke Test

The repository includes a 39-point smoke test suite:

./tests/smoke-test.sh ${ORIGIN_IP}

This validates all 9 applications, health endpoints, VAmPI registration/login, CSD Demo exfil round-trip, DVGA GraphQL, RESTaurant Swagger, crAPI on port 8888, nginx gzip, and version hiding.

Docker Container Status

SSH into the VM and verify all 41 containers are running:

ssh azureuser@${ORIGIN_IP} "sudo docker ps --format 'table {{.Names}}\t{{.Status}}\t{{.Ports}}'" | sort

Expected output (41 containers):

nginx Status

ssh azureuser@${ORIGIN_IP} "sudo nginx -t && sudo systemctl status nginx --no-pager"

Troubleshooting

Cloud-init still running

If endpoints return 502 or connection refused, cloud-init may still be provisioning:

ssh azureuser@${ORIGIN_IP} "cloud-init status"

status: running — still provisioning, wait a few minutes
status: done — provisioning complete, check Docker containers
status: error — check logs below

Cloud-init logs

ssh azureuser@${ORIGIN_IP} "sudo tail -100 /var/log/cloud-init-output.log"

Container not starting

# Check container logs (each app has 4 instances: -1 through -4)
ssh azureuser@${ORIGIN_IP} "sudo docker logs juice-shop-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs dvwa-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs vampi-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs httpbin-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs csd-demo-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs dvga-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs restaurant-1 2>&1 | tail -20"
ssh azureuser@${ORIGIN_IP} "sudo docker logs crapi-web 2>&1 | tail -20"

nginx returning 502

The upstream container is not ready or has crashed:

# Check nginx error log
ssh azureuser@${ORIGIN_IP} "sudo tail -20 /var/log/nginx/error.log"

# Restart all instances of a specific app
ssh azureuser@${ORIGIN_IP} "for i in 1 2 3 4; do sudo docker restart juice-shop-\$i; done"

# Rebuild and restart all containers
ssh azureuser@${ORIGIN_IP} "cd /opt/origin-server && sudo docker compose build && sudo docker compose up -d"

Disk space

Docker images consume approximately 4.7 GiB. Access logging is disabled to prevent disk exhaustion under CDN load testing. Logrotate is configured as defense-in-depth (500 MiB cap). Verify disk usage:

ssh azureuser@${ORIGIN_IP} "df -h / && sudo docker system df"

Container memory

Check for containers approaching their memory limits (OOM risk):

ssh azureuser@${ORIGIN_IP} "sudo docker stats --no-stream --format 'table {{.Name}}\t{{.MemUsage}}\t{{.MemPerc}}' | sort"

Restart everything

If needed, rebuild and restart all services:

ssh azureuser@${ORIGIN_IP} "cd /opt/origin-server && sudo docker compose down && sudo docker compose build && sudo docker compose up -d && sudo systemctl restart nginx"
