Docker Compose容器立即退出

Question

这两天我一直在和多克吵架，所以我真的希望有人能帮我。我想要的：一个Docker有一个正在运行的Kafka实例，另一个Docker有一个Python retriever脚本。我想要一个compose文件，它将构建所有三个映像（Kafka、Zookeeper和Python），并立即执行Python文件。我遇到的问题是，当我编写docker时，Kafka和Zookeeper容器正在工作，但是Python容器立即存在。有人能给我一种方法让Python容器继续运行，这样我就可以进入bash了吗？在

命令：docker-compose down && docker-compose -f docker-compose-swarm.yml up -d

编写docker-swarm.yml公司文件：

  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"

    ports:
      - target: 9094
        published: 9094
        protocol: tcp
        mode: host
    environment:
      HOSTNAME_COMMAND: "docker info | grep ^Name: | cut -d' ' -f 2"
