## Step four: Generate the private marketplace

Once the list in `extensions.txt` is ready, you can generate the marketplace:

{{< tabs group="os_version" >}}
{{< tab name="Mac" >}}

```console
$ /Applications/Docker.app/Contents/Resources/bin/extension-admin generate
```

{{< /tab >}}
{{< tab name="Windows" >}}

```console
$ C:\Program Files\Docker\Docker\resources\bin\extension-admin generate
```

{{< /tab >}}
{{< tab name="Linux" >}}

```console
$ /opt/docker-desktop/extension-admin generate
```

{{< /tab >}}
{{< /tabs >}}

This creates an `extension-marketplace` directory and downloads the marketplace metadata for all the allowed extensions.

The marketplace content is generated from extension image information as image labels, which is the [same format as public extensions](extensions-sdk/extensions/labels.md). It includes the extension title, description, screenshots, links, etc.

## Step five: Test the private marketplace setup

It's recommended that you try the private marketplace on your Docker Desktop installation.

1. Run the following command in your terminal. This command automatically copies the generated files to the location where Docker Desktop reads the configuration files. Depending on your operating system, the location is:

    - Mac: `/Library/Application\ Support/com.docker.docker`
    - Windows: `C:\ProgramData\DockerDesktop`
    - Linux: `/usr/share/docker-desktop`

   {{< tabs group="os_version" >}}
   {{< tab name="Mac" >}}

   ```console
   $ sudo /Applications/Docker.app/Contents/Resources/bin/extension-admin apply
   ```

   {{< /tab >}}
   {{< tab name="Windows (run as admin)" >}}

   ```console
   $ C:\Program Files\Docker\Docker\resources\bin\extension-admin apply
   ```

   {{< /tab >}}
   {{< tab name="Linux" >}}

   ```console
   $ sudo /opt/docker-desktop/extension-admin apply
   ```

   {{< /tab >}}
   {{< /tabs >}}

2. Quit and re-open Docker Desktop. 
3. Sign in with a Docker account.

When you select the **Extensions** tab, you should see the private marketplace listing only the extensions you have allowed in `extensions.txt`.

## Step six: Distribute the private marketplace

Once you’ve confirmed that the private marketplace configuration works, the final step is to distribute the files to the developers’ machines with the MDM software your organization uses. For example, [Jamf](https://www.jamf.com/).

The files to distribute are:
* `admin-settings.json`
* the entire `extension-marketplace` folder and its subfolders

These files must be placed on developer's machines. Depending on your operating system, the target location is (as mentioned above):

- Mac: `/Library/Application\ Support/com.docker.docker`
- Windows: `C:\ProgramData\DockerDesktop`
- Linux: `/usr/share/docker-desktop`

Make sure your developers are signed in to Docker Desktop in order for the private marketplace configuration to take effect. As an administrator, you should [enforce sign-in](/manuals/security/for-admins/enforce-sign-in/_index.md).
