Is it possible to show the `WORKDIR` when building a docker image?
<p>We have a problem with the <code>WORKDIR</code> when we building a docker image. Is it possible to print the value of <code>WORKDIR</code>?</p>

<p>We tried:</p>

<pre><code>ECHO ${WORKDIR}
</code></pre>

<p>But there is no such instruction <code>ECHO</code></p>
