通过docker-compose.yml修改docker容器内存限制

项目开发中需要对某些docker容器进行docker内存的限制

比如对某个项目，限制为7G

find  / -name docker-compose.yml

services:
  frontend:
    image: awesome/webapp
    deploy:
      resources:
        limits:
          cpus: '0.50'
          memory: 50M
          pids: 1
        reservations:
          cpus: '0.25'
          memory: 20M
