Override .dockerignore file when using ADD : <p>I have one Rockerfile that builds 4 images; I also have one central <code>.dockerignore</code> file. For one of the images I require assets that are blocked by the <code>.dockerignore</code> file -- is there a way when doing <code>ADD</code> or <code>COPY</code> to force add / ignore this list?</p>

<p>It'll be a lot easier to do this in one file as opposed to three separate...!</p>
