title: Pass ARGs in docker ENTRYPOINT
body: <p>I'm running my app on Azure App Services, so I don't have access to <code>docker run</code> command. Now, I want to pass some variables into ENTRYPOINT for which I'm trying to use ARGs during build time itself. Here is how it looks,</p>
  
  <pre><code>docker build -t $IMAGE_NAME --build-arg env=dev --build-arg amplify_key=xxxxxxxxxxxxxx .
  </code></pre>
  
  <p>In my Dockerfile,</p>
  
  <pre><code>ARG env
  ARG amplify_key
  
  ENTRYPOINT ["/bin/bash", "-c", "init.sh $env $amplify_key"]
  </code></pre>
  
  <p>But this doesn't seem to be working. Please let me know the issue.</p>
