title: Use programs installed on Docker base image
body: <p>This is something that's been bugging me for a while, but how come I can't access programs that are installed in my base image in my Docker image?</p>
  
  <p>For example, my base image has make &amp; gcc installed. However, in my current image that I am accessing via <code>docker run</code>, I can't access make or gcc despite having <code>FROM base img</code> . I get <code>bash: make: command not found</code>.</p>
