db-data:docker-stack.yml 是 Compose file 中的一个新文件类型，只和Compose Version 3兼容。
deploy 关键字，允许我们指定一个集群部署（swarm deployment）的各种特性。
比如，voting app 配置中，使用这个关键字，创建了 vote 和 result services 的副本(每个service有两个 container，被部署到swarm集群中).
voting app 同样使用 deploy 约束某些services只能够在manager node中执行。
该命令只支持 version: "3" 的Compose files.
不支持关键字 build ，这之前是在标准 Compose files中被支持的, 而Compose file则是基于 Dockerfile的。为了使用 docker stack deploy，我们需要使用 pre-built image
它可以替代命令 docker compose up 来运行与 Version 3 兼容的 applications.
