# Makefile for EC integration testing
# Usage:
#   make start      - Start the test cluster (master + 6 volume servers + filer)
#   make stop       - Stop the test cluster
#   make populate   - Populate test data (~300MB across 7 volumes)
#   make shell      - Open weed shell connected to the test cluster
#   make clean      - Stop cluster and remove all test data
#   make setup      - Start cluster and populate data (one command)
#
# Requirements: curl, jq
