title: Specify environment on start of component
body: <p>We are having docker based build and deployment and below mentioned is our <em>docker-compose.yml</em> file.</p>
  
  <pre><code>web:
    image: stage.example.com/logcomponent:latest
    ports:
      - "80"
    environment:
      NODE_ENV: DEV
  </code></pre>
  
  <p>We are running it using <code>docker-compose up -d</code>. Is there a way to specify <code>NODE_ENV</code> value from command like for e.g. <code>docker-compose up -d PROD</code> or <code>docker-compose up -d DEV</code>?</p>
  
  <p>Thanks in advance.</p>
