title: How to download microdnf in maven:3.6.3-openjdk-8?
body: <p>I have the following Docker file. When I run for 'maven:3.6.3-openjdk-8' I get '/bin/sh: 1: microdnf: not found' but I get no such message when 'maven:3.6.3-openjdk-15' runs. Does anyone know how to download microdnf when using 'maven:3.6.3-openjdk-8'? Docker file follows:</p>
  <pre><code>FROM maven:3.6.3-openjdk-15

  RUN microdnf install -y google-chrome-stable-$CHROME_VERSION \
      &amp;&amp; sed -i 's/&quot;$HERE\/chrome&quot;/&quot;$HERE\/chrome&quot; --no-sandbox/g' /opt/google/chrome/google-chrome
