当使用GitLab CI以及gitlab-ci-multi-runner时，我无法使内部启动的Docker容器将其端口暴露给“主机”，即运行构建的Docker镜像。

我在这里做错了什么？
以下是原始问题 - 上面是一个更短、更易于测试的示例
我有一个应用程序镜像，监听端口9143。它的启动和配置是通过docker-compose.yml管理的，在我的本地机器上使用docker-compose up非常好用 - 我可以轻松访问localhost:9143。
然而，在GitLab CI（gitlab.com版本）上运行时，该端口似乎没有被暴露。
我的.gitlab-ci.yml的相关部分：
test:
image: craigotis/buildtools:v1
stage: test
script:
- docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com/craigotis/myapp
- docker-compose up -d
- sleep 60 # a temporary hack to get the logs
- docker-compose logs
- docker-machine env
- docker-compose port app 9143
- netstat -a
- docker-compose ps
- /usr/local/bin/wait-for-it.sh -h localhost -p 9143 -t 60
- cd mocha
- npm i
- npm test
- docker-compose down
输出结果为：
$ docker-compose logs

services:

depends_on:

看起来我的应用程序容器正在监听 9143，并且已经正确地暴露给共享的 GitLab runner，但似乎实际上并没有暴露出来。它在我的本地机器上运行良好 - 在运行在 GitLab 上的 Docker 容器中工作需要做一些特殊的解决方法/调整吗？
