title: Missing dependencies after using docker-compose
body: <p>I'm still pretty new to docker, but I finally understood the differences between docker-compose and plain docker command, I would like to deploy some containers for my dev environment which includes a backend with nest.js and a postgress database (Further down the line I will include a React App and maybe PGAdmin).</p>
  <p>The image for my backend server works fine when I run it with <code>docker run</code> but it looks like it has trouble with <code>docker-compose</code> where some dependencies are missing (even though they are being installed with <code>npm install</code>?).</p>
  <p>Here's the docker file for my backend server.</p>
  <pre><code>FROM node:14-alpine
  
  WORKDIR /usr/src/app
  
  COPY . .
  
  # If I don't install nest's cli the app won't start telling me nest was not found.
  RUN npm install -g @nestjs/cli 
  # Install all dependencies
  RUN npm install
  
  # package.json start script
  CMD [ &quot;npm&quot;, &quot;run&quot;, &quot;start:dev&quot;]
  </code></pre>
  <p>And this is my <code>docker-compose</code> file.</p>
  <pre class="lang-yaml prettyprint-override"><code>

  <p>This is the output when I check the logs on the container for my backend image.</p>

  <p>My project is using a monorepo with yarn workspaces, could this be causing any trouble?</p>
