这是我的设置:
两个不同的 docker 镜像，一个用于开发，一个用于测试。以及利用这些图像的两个不同的 docker-compose 文件

当我当时使用单个撰写文件时，一切正常。
示例:
只运行开发容器。

仅运行测试容器。

问题:
当我尝试同时运行两个容器时，问题就开始了。也就是说，docker-compose -f composer-development.yml up -d触发的development容器已经在运行。现在我开始我的 testing 容器 docker-compose -f composer-testing.yml up -d 这就是发生的事情。
lukas@E7450: docker-compose -f composer-testing.yml up

Recreating compare_dev_webapp

docker-compose 不知何故决定重新创建并停止 developement 容器 - 只留下 testing 容器。我期望的是同时运行两个容器(开发和测试容器)我所拥有的只是测试容器!

问题:
为什么我不能同时运行这两个容器？为什么启动 testing 容器会停止 development 容器？如何并行运行这两个容器？</p>
最佳答案
您可以，compose 只是将其视为同一个项目，因为您从同一目录运行并且没有定义项目。所以它使当前项目看起来像你上次给它的 compose 文件。
要同时运行它们，请像这样运行它们:
docker-compose -f composer-development.yml -p dev up -d
docker-compose -f composer-testing.yml -p test up -d
关于docker-compose 无法运行两个容器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39489327/
