# Docker Compose stress test with receiver
|
|
# See README.md "Docker Compose" section for the full token workflow.
|
|
#
|
|
# This test:
|
|
# 1. Starts the metrics receiver (with read-token and hmac-key)
|
|
# 2. You generate a scoped push token via POST /api/v1/token
|
|
# 3. Start the collector with COLLECTOR_PUSH_TOKEN set
|
|
# 4. Runs heavy CPU/memory workloads in multiple containers with shared PID namespace
|
|
# 5. Collector gathers metrics and pushes summary to receiver on shutdown
|
|
#
|
|
# To trigger the push, stop the collector gracefully:
|
|
# docker compose -f test/docker/docker-compose-stress.yaml stop collector
|
|
|
|
services:
|
|
# Metrics receiver - stores summaries in SQLite
