Use sudo inside Dockerfile (Alpine) : <p>I have this Dockerfile ...</p>

<pre><code>FROM keymetrics/pm2:latest-alpine

RUN apk update &amp;&amp; \
    apk upgrade &amp;&amp; \
    apk add \
       bash

COPY . ./

EXPOSE 1886 80 443

CMD pm2-docker start --auto-exit --env ${NODE_ENV} ecosystem.config.js
</code></pre>

<p>How can I execute the <code>CMD</code> command using <code>sudo</code> ?</p>

<p>I need to do this because the port 443 is allowed only for sudo user.</p>
