docker不能运行两个容器

Question

这是我的设计：

两个不同的坞映像，一个用于开发，另一个用于测试。以及利用这些图像的两个不同的停靠文件。

当我当时处理单个组合文件时，一切都很好。

示例：

只运行开发容器。

lukas@E7450:~$ docker-compose -f composer-development.yml up -d
lukas@E7450:~$ docker ps

只运行测试容器。

lukas@E7450:~$ docker-compose -f composer-testing.yml up -d
lukas@E7450:~$ docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                                        NAMES

9f78d61a19f8        postgres:9.5.3            "/docker-entrypoint.s"   11 seconds ago      Up 11 seconds       5432/tcp                                     compare_test_postgres

问题：

当我试图同时运行两个容器时，问题就开始了。也就是说，开发容器已经由docker -f composer-Development.ymlup -d触发。现在，我开始我的测试，容器码头-编写-f作曲家-测试。start -d，这就是所发生的事情。

lukas@E7450: docker-compose -f composer-testing.yml up
Recreating compare_dev_postgres
Recreating compare_dev_webapp
Recreating compare_dev_redis
Recreating compare_dev_varnish
Attaching to compare_test_postgres, compare_test_webapp, compare_test_varnish, compare_test_redis

不知何故，码头-组合决定重新创建和停止developement容器-leaving me只与测试容器。我所期望的是，有两个容器同时运行(开发和测试容器)，而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？为什么启动测试容器会停止开发容器？如何并行运行这两个容器？

Answer 1

您可以，因为您是从同一个目录运行的，所以compose只是将其视为相同的项目，而不定义项目。因此，它使当前的项目看起来像您最后给它的撰写文件。

要并行地运行两者，请运行它们，如下所示：

docker-compose -f composer-development.yml -p dev up -d

docker-compose -f composer-testing.yml -p test up -d
