# PyClaw multi-worker deployment.
#
# 3 active-active workers behind nginx (ip_hash + Session Affinity Gateway),
# Redis as shared session/affinity/lock store, healthcheck on every service.
#
# Usage:
#   cp deploy/.env.example deploy/.env
#   # edit deploy/.env to set PYCLAW_WEB_JWT_SECRET / admin password / API keys
#   docker compose -f deploy/docker-compose.multi.yml --env-file deploy/.env up -d
#
# Single entry point: http://localhost (nginx proxies to the 3 workers).
#
# To scale up: change replicas + add to nginx upstream block in deploy/nginx.conf.
