`docker pull` prior to use. Otherwise, it is assumed the image already
exists and can be used. This defaults to true if not set.
## Using the generated artifact
Once the tar artifact has been generated, you will likely want to import, tag, and push it to a container repository.Until packer supports management of the docker image metadata, this process is manual. For example, the following will import mycontainer-123456789.tar as the repository registry.mydomain.com/mycontainer, tagged with 'latest':
<pre class="prettyprint">
sudo docker import - registry.mydomain.com/mycontainer:latest < mycontainer-123456789.tar
</pre>
You can then add additional tags and push the image as usual with docker tag and docker push, respectively.
## Dockerfiles
This builder allows you to build Docker images _without_ Dockerfiles.
