我使用以下撰写文件进行堆栈部署

version: '3.8'
x-deploy: &Deploy
  replicas: 1
  placement: &DeployPlacement
    max_replicas_per_node: 1
  restart_policy:
    max_attempts: 15
    window: 60s
  resources: &DeployResources
    reservations: &DeployResourcesReservations
      cpus: '0.05'
      memory: 10M
services:
  serv1:
    image: alpine
    networks:
      - test_nw
    deploy:
      <<: *Deploy
    entrypoint: ["tail", "-f", "/dev/null"]
  serv2:
    image: nginx
    networks:
      - test_nw
    deploy:
      <<: *Deploy
      placement:
        <<: *DeployPlacement
        constraints:
          - "node.role!=manager"
    expose: # deprecated, but I leave it here anyway
      - "80"
networks:
  test_nw:
    name: test_nw
    driver: overlay

为了方便起见，我将使用test_serv1running via containerinhost1和test_serv2running …
