title: How to access the metadata of a docker container from a script running inside the container?
body: <p>I am trying to understand whether it is possible to read the metadata (Labels, in particular) properties of a container using a bash script.</p>
  
  <p>For instance, if there is a Dockerfile like:</p>
  
  <pre><code>FROM busybox
  LABEL abc = abc_value1
  </code></pre>
  
  <p>And, if I build and run an image based on the file above, like so:</p>
  
  <pre><code>docker build . -t image1
  docker run -ti image1 /bin/bash
  </code></pre>
  
  <p>Is there any way to access the value of the "abc" label inside the bash shell?  If so, how?</p>
