 <div class="title">Workspace-specific images</div>
 <p>The images described in this section are required for running a workspace. Any one workspace uses a subset of the images below. It is only necessary to include the images that are used in workspaces created. For example, when using Che only for developing in Java, many images can be omitted.</p>
 </div>
 <div class="paragraph">
 <p>To avoid issues when only a subset of the images described in this section is needed, remove unnecessary plug-ins and devfiles when building custom registries (see <a href="../../administration-guide/customizing-the-registries/" class="page">Customizing the registries</a> for more information).</p>
 </div>
 <div class="paragraph">
 <div class="title">Plug-in sidecar images</div>
 <p>Many workspace plug-ins are run in sidecar containers to ensure their dependencies are available. The offline plug-in registry (see <a href="#building-an-offline-plug-in-registry-image_che">Building an offline plug-in registry image</a>) includes a file with the list of all images referenced in its plug-ins.</p>
 </div>
 <div class="paragraph">
 <p>To get a list of images required for plug-ins, display this file:</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre>$ docker run -it --rm \
   --entrypoint cat <em>&lt;my-offline-registry&gt;</em> /var/www/html/v3/external_images.txt</pre>
 </div>
 </div>
 <div class="paragraph">
 <p>In the example above, substitute <code>&lt;my-offline-registry&gt;</code> for the image name and tag of the custom plug-in registry.</p>
 </div>
 <div class="paragraph">
 <div class="title">Devfile base images</div>
 <p>Every Che workspace uses one or more <em>base</em> images, which contain the development dependencies for projects that are being built. To use the samples, Che pull these images from the references to them in the devfile registry. This is needed because the sample devfiles included in the devfile registry apply to images suited for this purpose.</p>
 </div>
 <div class="paragraph">
 <p>An offline devfile registry (see <a href="#building-an-offline-devfile-registry-image_che">Building an offline devfile registry image</a>) contains a file with the list of all images referenced in its devfiles:</p>
