title: python3 nodejs docker images
body: <p>I am working with a django angular project. I am using python3 so I want a container where node 6.4.0 and python3 will be installed. I have node:6.4.0 and python:3.4 images in my docker.</p>
  
  <p>Now I want another images named py3node.
  I am trying this way:</p>
  
  <ol>
  <li><p>Dockerfile:</p>
  
  <pre><code>FROM node:6.4.0
  FROM python:3.4
  </code></pre></li>
  <li><p>docker build -t py3node</p>
  
  <pre><code>output:
  
  Sending build context to Docker daemon 8.192 kB
  Step 1 : FROM node:6.4.0
  ---&gt; 800da22d0e7b
  Step 2 : FROM python:3.4
  ---&gt; 93bc8e41eb8c
  Successfully built 93bc8e41eb8c
  </code></pre></li>
  </ol>
  
  <p>Then I run:</p>
  
  <pre><code>docker run -it py3node /bin/bash
  
  root@092724f514:/# node -v
  
  output:
  bash: node: command not found
  </code></pre>
  
  <p>But python3 works. Why node:6.4.0 is not working?</p>
