docker-compose 限制内存，CPU

docker-compose 使用3.7版本，然后加入 deploy，例如：

version: "3.7"
services:
  redis:
    image: redis:alpine
    container_name: testredis
    deploy:
      resources:
        limits:
          cpus: '0.50'
          memory: 500M

限制 CPU 使用率 50%， 500MB 内存

需要注意的是，启动时需增加 –compatibility 选项

docker-compose --compatibility up -d

否则会报错

WARNING: Some services (mysql, rsnmp) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.

注：

–compatibility是docker-compose 1.20.0加入，主要目的就是用来将deploy中的数据限制、replicas与重启策略直接转译为version 2的语法
