# ============================================================
# iotlcm 内存上限 override —— 8 vCPU / 32 GB 宿主机，与其他服务共用
#
# 定位：这台机器是「一机多环境」，iotlcm 只是其中一个占用方。
#       所以只给全套 20 个服务留 **约 8.5 GB 上限**（实测常驻约 2 GB），
#       剩余 20+ GB 留给宿主机上要新增的其它服务。
#
# 没有本文件会怎样：编排里没有内存限制，任何一个服务泄漏/跑批都会
# 把整机内存吃到 OOM Killer 随机杀进程（表现为容器反复 Restarting
# 且日志里看不到业务异常，只能 dmesg 里看到 oom-kill）。
#
# 用法（顺序不能反）：
#   docker compose -f docker-compose.yml -f compose.memlimit.yml up -d
#
# 只调 resources（+ MySQL 自身缓存参数），不动镜像、端口、卷、依赖。
# 换成更小的机器（4 GB）时按比例下调：mysql 1024M / tdengine 512M /
# worker-svr 768M / 其余 320M；8 GB 机器可用 1024M / 768M / 512M。
