| <p>Che plug-ins are extensions to the Che-Theia IDE that come bundled with a container image that contains their native prerequisites (for example, the OpenShift Connector plug-in needs the <code>oc</code> command installed). Plug-ins can also include metadata to define a description, categorization tags, and an icon. |
| Che provides a registry of plug-ins available for installation into the user’s workspace.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Che-Theia IDE is generally compatible with the VS Code extensions API. This means that many VS Code extensions are automatically compatible with Che-Theia, and can be packaged as Che plug-ins by combining them container that contains their dependencies. By default, Che includes a plug-in registry containing common plug-ins.</p> |
| </div> |
| <div class="paragraph"> |
| <p>From the Dashboard, plug-ins in the registry can be added from the <strong>Plugin</strong> tab in the <strong>Workspace details</strong> page, or by adding them directly into a devfile. The devfile can also be used for further configuration of the plug-in, such defining memory or CPU usage. |
| Alternatively, plug-ins can also be installed from within the Che-Theia IDE by pressing <span class="keyseq"><kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>J</kbd></span> or by navigating to <strong>View → Plugins</strong>.</p> |
