title: Why is docker build not showing any output from commands?
body: <p>Snippet from my <code>Dockerfile</code>:</p>
  <pre><code>FROM node:12.18.0
  RUN echo &quot;hello world&quot;
  RUN psql --version
  </code></pre>
  <p>When I run <code>docker build .</code> I don't see any output from these two commands even if they are not cached. The documentation says that <code>docker build</code> is verbose by default. Why am I not seeing the output from commands? I used to see them before.</p>
  <p>The output while building:</p>
  <pre><code>=&gt; [7/18] RUN echo &quot;hello world&quot;                         0.9s
  </code></pre>
  <p>The output I am seeing after building finishes:</p>
  <pre><code>=&gt; CACHED [6/18] RUN apt-get install postgresql -y      0.0s
  =&gt; [7/18] RUN echo &quot;hello world&quot;                        6.4s
  =&gt; [8/18] RUN psql --version                           17.1s
  </code></pre>
  <p>The <code>Dockerfile</code> is created from node:12.18.0 which is based on Debian 9.</p>
  <p>Docker version 19.03.13, build 4484c46d9d.</p>
