title: Run gauge tests inside a docker container
body: <p>I'm trying to Dockerize a Gauge test automation project so I can run specs inside a Docker container. The project is written in Java and Spring Boot.</p>
  
  <p>I saw this <a href="https://docs.gauge.org/howto/ci_cd/docker.html?os=linux&amp;language=java&amp;ide=null" rel="nofollow noreferrer">tutorial</a> in Gauge documentation.</p>
  
  <p>This is the DockerFile in the tutorial:</p>
  
  <pre><code>FROM ubuntu
  
  # Install Java.
  RUN apt-get update &amp;&amp; apt-get install -q -y \
      openjdk-8-jdk \
      apt-transport-https \
      gnupg2 \
      ca-certificates
  
  # Install gauge
  RUN apt-key adv --keyserver hkp://ipv4.pool.sks-keyservers.net --recv-keys 023EDB0B &amp;&amp; \
      echo deb https://dl.bintray.com/gauge/gauge-deb stable main | tee -a /etc/apt/sources.list
  
  RUN apt-get update &amp;&amp; apt-get install gauge
  
  # Install gauge plugins
  RUN gauge install java &amp;&amp; \
      gauge install screenshot
  
  ENV PATH=$HOME/.gauge:$PATH
  </code></pre>
  
  <p>As you see, there's no "ADD"/"COPY" there in the DokcerFile.</p>
  
  <p>Is it just suggesting an alternative to install Gauge and the other packages on the host?</p>
  
  <p>Any ideas on how to run the specs inside a Docker container?</p>
