Docker撰写图像失败

Question

我正在学习Dockerfiles和docker-compose。当我手动运行Dockerfiles并创建容器时，它们都可以正常工作，但是通过触发构建并使用docker-compose.yml脚本进行部署，订阅容器将停止工作。

成功运作的过程是：

docker build -t cu/broker:1.0.0 broker/
docker run -d --name broker -p 6379:6379 cu/broker:1.0.0
docker build -t cu/subscriber:1.0.0 subscriber/
docker run -d --name subscriber --link broker:db cu/subscriber:1.0.0
docker build -t cu/publisher:1.0.0 publisher/
docker run --name publisher --link broker:db -ti cu/publisher:1.0.0

运行这些命令后，我有两个正在运行的容器和一个交互式控制台，我可以将个别发布命令发送到redis服务器。

我没有将每个脚本与文件夹结构一起添加到此问题中，而是编写了一个shell脚本，可以重置所有内容并生成正确的结构和文件。

当我触发docker-compose.yml脚本时，它成功完成，但只有代理容器正在运行，其他两个脚本一启动就会终止。我不明白为什么，甚至使用--verbose标志我没有得到有用的信息来帮助调试这个。这是我用来运行脚本的命令。

docker-compose --verbose up -d

这是构建文件夹和文件结构的shell脚本config.sh。
