泊坞窗集装箱未能运行

的Dockerfile我的应用如下泊坞窗集装箱未能运行

   # Tells the Docker which base image to start. 
       FROM node 

       # Adds files from the host file system into the Docker container. 
       ADD . /app 

       # Sets the current working directory for subsequent instructions 
       WORKDIR /app 

       RUN npm install 
       RUN npm install -g bower 
       RUN bower install --allow-root 
       RUN npm install -g nodemon 

       #expose a port to allow external access 
       EXPOSE 9000 9030 35729 

       # Start mean application 
       CMD ["nodemon", "server.js"]

泊坞窗，compose.yml文件如下

      web: 
           build: . 
           links: 
              - db 
            ports: 
              - "9000:9000" 
              - "9030:9030" 
              - "35729:35729" 
            db: 
              image: mongo:latest 
              ports: 
                - "27017:27017"

而产生的，同时运行如下的错误： -

在docker中，您无法通过本地主机连接到其他容器，因为每个容器都是独立的，并且拥有自己的IP。你应该使用container_name:port。在你的例子中，它应该是db:27017从'web'中的NodeJS应用程序连接到'db'中的MongoDB。

所以这不是你的Dockerfile的问题。这是来自NodeJS应用程序的指向localhost而不是db的连接URL。

我已经更改了我的应用程序配置文件。上面指定的数据库问题已解决。但是应用程序不会在端口9000,9030上加载。 – cmr

我想你正在使用Boot2Docker。 Boot2Docker有一个自己的IP地址，因为它是一个虚拟机。您可以使用像[这里]（https://stackoverflow.com/questions/28403341/boot2docker-access-webserver-as-localhost#28405278）的端口转发，或者您可以通过docker inspect $获得Boot2Docker IP（docker ps - q）| grep IPA'并使用它像Boot2DockerIP：端口，因为端口被转发到Boot2Docker。 – Piu130
