# app2container extract command
<a name="cmd-extract"></a>

Generates an application archive for the specified application. Before you call this command, you must call the [analyze](cmd-analyze.md) command.

**Note**  
If the command fails, an error message is displayed in the console, followed by additional messaging to help you troubleshoot.  
When you ran the **init** command, if you chose to automatically upload logs to App2Container support if an error occurs, App2Container notifies you of the success of the automatic upload of your application support bundle.  
Otherwise, App2Container messaging directs you to upload application artifacts by running the [upload-support-bundle](cmd-upload-support-bundle.md) command for additional support.
