将docker容器部署到heroku

我在本地使用docker composer构build了一个web应用程序。 dockercomposer php有多个服务，它们有各自的docker文件，如下所示：

version: '2' services: # The Application app: build: context: ./ dockerfile: app.dockerfile working_dir: /var/www volumes: - ./:/var/www environment: - "DB_PORT=3306" - "DB_HOST=database" # The Web Server web: build: context: ./ dockerfile: web.dockerfile working_dir: /var/www volumes_from: - app ports: - 9002:80 # The Database database: image: mysql:5.6 volumes: - dbdata:/var/lib/mysql environment: - "MYSQL_ROOT_PASSWORD=****" - "MYSQL_DATABASE=****" - "MYSQL_USER=***" ports: - "33061:3306" #Cache memcached: image: memcached ports: - "11211:11211" mem_limit: 1g command: memcached -m 1024m volumes: dbdata: 

如何将我的应用程序部署到heroku？ 可以使用docker撰写文件来完成吗？ 或者我需要build立一个图像。 我是新来的heroku。 请帮忙。

更新：下面是我的docker images命令的输出：
