docker - Docker Compose 3控制资源(内存，CPU)

Question

我正在尝试使用docker compose版本3文档(https://docs.docker.com/compose/compose-file/)中的“resources”字段，但是，我遇到了一个错误，

ERROR: The Compose file './docker-compose.yml' is invalid because: Unsupported config option for services.fstore_java: 'resources'

如何使用docker-compose设置内存限制？

  fstore_java:
    depends_on:
      - fstore_db
      - rabbit_broker
    build: ./fstore
    ports:
      - "8080:8080"
    expose:
      - "8080"
    links:
      - fstore_db
      - rabbit_broker
    restart: always
    resources:
      limits:
        cpus: '0.001'
        memory: 50M

Answer 1

必须在“部署”级别下

  fstore_java:
depends_on:
  - fstore_db
  - rabbit_broker
build: ./fstore
ports:
  - "8080:8080"
expose:
  - "8080"
links:
  - fstore_db
  - rabbit_broker
restart: always
deploy:
  resources:
    limits:
      cpus: '0.001'
      memory: 50M
