Pm2 不绑定 docker 个端口

Question

我正在构建一个节点 api 样板文件，其中包含 docker、babel、istanbul、pm2、eslint 和其他功能。我的项目在 nodemon 的开发模式下运行良好，在 mocha 的测试模式下也运行良好。但是，当我运行 prod 模式下的项目使用 pm2 时，docker 端口不绑定。

完整的项目可以在这里找到https://github.com/apandrade/node-api-boilerplate

在寻找解决方案几天后，我发现不存在任何问题，发生的是运行我的项目运行 docker-compose run --rm <service_name> 并且docker撰写参考明确

the docker-compose run command does not create any of the ports specified in the service configuration. This prevents port collisions with already-open ports. If you do want the service’s ports to be created and mapped to the host, specify the --service-ports flag:

docker-compose run --service-ports <service_name>

但是我选择运行 docker-compose up <service_name>，这对我来说已经足够了，因为我没有特定的需要如何覆盖命令或运行不同端口上只有一个容器.
