title: How to check if a Docker image with a specific tag exist locally?
body: <p>I'd like to find out if a Docker image with a specific tag exists locally. I'm fine by using a bash script if the Docker client cannot do this natively.</p>
  
  <p>Just to provide some hints for a potential bash script the result of running the <code>docker images</code> command returns the following:</p>
  
  <pre><code>REPOSITORY                               TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
