docker swarm 内存和cup占用优化

启动container时加入–compatibility参数

docker-compose --compatibility up -d

version: "3.7"
services:
  redis:
    image: redis:alpine
    container_name: testredis
    deploy:
      replicas: 1
      restart_policy:
    	condition: on-failure
      resources:
        limits: 
         cpus: '0.03' 
         memory: 700M
        reservations: 
         cpus: '0.03' 
         memory: 300M

–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

由于做了资源限制, 并且没有使用swarm, 所以要加上--compatibility参数, 不然会报错

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