Docker Build can't find pip
<p>Trying to follow a few[<a href="https://aws.amazon.com/blogs/aws/run-docker-apps-locally-using-the-elastic-beanstalk-eb-cli/" rel="noreferrer">1</a>][<a href="http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_dockerpreconfig.walkthrough.html" rel="noreferrer">2</a>] simple Docker tutorials via AWS am and getting the following error:</p>

<pre><code>&gt; docker build -t my-app-image .

</code></pre>

<p>Dockerfile:</p>

<pre><code># For Python 3.4
FROM amazon/aws-eb-python:3.4.2-onbuild-3.5.1
</code></pre>

<p>Which pip returns the following:</p>

<pre><code>&gt; which pip                                                             
./bin/pip
</code></pre>

<p>Relevant file structure:</p>

<pre><code>.
├── Dockerfile
├── bin
│   ├── activate
│   ├── pip
│   ├── pip3
│   ├── pip3.5

</code></pre>

<p>Again, noob in all things Docker so I'm not sure what troubleshooting steps to take. Please let me know what other helpful information I can provide.</p>
