### Resources
The **Resources** tab allows you to configure CPU, memory, disk, proxies, network, and other resources.
The **Resources** tab allows you to configure CPU, memory, disk, proxies,
network, and other resources. Different settings are available for
configuration depending on whether you are using Linux containers in WSL 2
mode, Linux containers in Hyper-V mode, or Windows containers.

#### File sharing

Use File sharing to allow local drives on Windows to be shared with Linux containers.
This is especially useful for
editing source code in an IDE on the host while running and testing the code in a container.
Note that configuring file sharing is not necessary for Windows containers, only [Linux containers](#switch-between-windows-and-linux-containers).
If a drive is not shared with a Linux container you may get `file not found` or `cannot start service` errors at runtime. See [Volume mounting requires shared drives for Linux containers](troubleshoot.md#volume-mounting-requires-shared-drives-for-linux-containers).
**Apply & Restart** makes the drives available to containers using Docker's bind mount (`-v`) feature.

You can configure Docker Desktop networking to work on a virtual private network (VPN). Specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity.

Updating these settings requires a reconfiguration and reboot of the Linux VM.
#### WSL Integration
In WSL 2 mode, you can configure which WSL 2 distributions will have the Docker
WSL integration.
By default, the integration will be enabled on your default WSL distribution.
To change your default WSL distro, run `wsl --set-default <distro name>`. (For example,
to set Ubuntu as your default WSL distro, run `wsl --set-default ubuntu`).
You can also select any additional distributions you would like to enable the WSL 2
integration on.
For more details on configuring Docker Desktop to use WSL 2, see
[Docker Desktop WSL 2 backend](wsl.md).
### Docker Engine
The Docker Engine page allows you to configure the Docker daemon to determine how your containers run.

### Kubernetes
> **Note**

> The Kubernetes tab is not available in Windows container mode.
Docker Desktop includes a standalone Kubernetes server that runs on your Windows host, so that you can test deploying your Docker workloads on Kubernetes.
