title: Dockerfile compatibility with Raspberry Pi?
body: <p>I have built the image from the following Dockerfile in my Rpi Kubernetes cluster. However, I was getting status of <code>CrashLoopBackOff</code> for my Pods. </p>
  
  <p>After a bit of search on the internet, I realized that the problem maybe is with the <code>Dockerfile</code>'s compatibility with RPi.
  I get following error when I run <code>docker logs CONTAINER_ID</code> </p>
  
  <p><code>standard_init_linux.go:190: exec user process caused "exec format error"</code></p>
  
  <p>The Dockerfile:</p>
  
  <pre><code>FROM ubuntu:18.04
  
  RUN apt-get update &amp;&amp; apt-get install -y \
      git \
      software-properties-common \ 
      python3-pip git
  RUN add-apt-repository universe \
      &amp;&amp; apt-get update
  RUN pip3 install tornado sqlalchemy construct==2.5.5-reupload
  RUN git clone https://github.com/majadoon/empower-runtime.git
  RUN cd empower-runtime \
      &amp;&amp; mkdir deploy
  
  EXPOSE 8000 4433
  
  WORKDIR /empower-runtime
  
  CMD ["./empower-runtime.py"]
  </code></pre>
  
  <p>Moreover, I get the following error on Rpi if I build the same image on Pi:</p>

  <p>EDIT: the problem seems to be at <code>git</code> and also at <code>apt-get install git</code> or  because running both separately give me the following error:</p>
