compose.loadtest.yml

# Load Testing Infrastructure
# Runs Locust and k6 alongside the main stack.
#
# Usage:
#   1. Ensure the main stack is running:
#      ./nukelabctl start
#
#   2. Seed test users:
#      ./nukelabctl exec backend python -m tests.load.setup_test_data --users 100
#
#   3. Run Locust with Web UI:
#      docker compose -f compose.loadtest.yml up locust
#      Open http://localhost:8089
#
#   4. Run k6 stress test:
#      docker compose -f compose.loadtest.yml run --rm k6 run /scripts/api-stress.js
#
#   5. Or use the convenience script:
#      ./scripts/run-load-tests.sh baseline

services:
  # Backend override: disable rate limiting and request metrics so load tests
  # measure actual API/DB capacity without observability write pressure.

      - RATE_LIMIT_ENABLED=false
