So, I have 3 files:

* client.js
* app.js
* database.js

In the app.js file, I have created an express server with multiple services that connect to the database. The client.js file runs the services, using node-fetch.

So far, I have created a Dockerfile to run app.js:

```
FROM node:10
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
CMD node app
EXPOSE 3000

```

Perhaps this is a dumb question but, is there any way to create another Dockerfile to run the client.js inside a container?

Thank you.
