title: Deploying Docker Container Registry on Azure App Service Issue
body: <p>I am unable to rum Docker Container Registry on the Azure App service. I have a flask app and the following is the Dockerfile of it:-</p>
  <pre><code>FROM python:3.8-slim-buster
  WORKDIR /usr/src/app
  COPY requirements.txt .
  RUN pip install --no-cache-dir -r requirements.txt
  
  # copy project
  WORKDIR /usr/src/app
  COPY . /usr/src/app/
  
  # expose port 80
  EXPOSE 80
  CMD [&quot;gunicorn&quot;, &quot;-w&quot;, &quot;4&quot;, &quot;-b&quot;, &quot;0.0.0.0:80&quot;, &quot;app:app&quot;]
  </code></pre>
  <p>I have deployed the docker image on the Container Registry. I have also set WEBSITES_PORT to 80 under App Service -&gt; Application Settings.
  Even after doing that, I get the following error:-</p>
  <pre><code>  ERROR - Container XYZ didn't respond to HTTP pings on port: 80, failing site start.
  </code></pre>
  <p>I have tried running it locally and it works fine. But, it just does not seem to work on the Azure App service. Any help is highly appreciated.</p>
