# Create shared storage service for Python


Zerops provides [shared storage service](/shared-storage/overview) that can be connected to runtime services. Shared storage enables your Python service to share files between all containers of the same service or even among containers of different runtime services.

## Connect shared storage in Zerops GUI

### When creating new shared storage

Connect your Python service directly when creating a new shared storage service. Select your Python service in the **Share with Services** block on the **Add new shared storage service** page.

### Connect existing shared storage

To connect existing shared storage to your Python service:

1. Go to the shared storage service detail page
2. Select **Shared storage connections**
3. Choose your Python service from the list of runtime services
4. The shared storage will be connected to your service

### How it works

Zerops creates a new folder `/mnt/[shared storage name]` in your Python service's root directory. For example, `/mnt/teststorage` for a `teststorage` shared storage.

The content of this folder is shared among:
- All containers of your Python service
- All containers of other connected runtime services (if you connect multiple services)

## Disconnect shared storage

To disconnect shared storage from your Python service:

1. Go to the shared storage service detail page
2. Select **Shared storage connections**
3. Switch off the toggle next to your Python service

## Create Python service with shared storage using zCLI

zCLI is the Zerops command-line tool. To create a new Python service with shared storage via command-line:

1. [Install & setup zCLI](/references/cli)
2. [Create a project description file](#create-project-description-file)
3. [Create the project](#create-project-with-shared-storage)

### Create project description file

Zerops uses YAML format to describe project infrastructure. [Read the basics](/python/how-to/create#create-a-project-description-file) about defining Python services in `description.yaml`.

#### Example with shared storage

Create a directory `my-project` and add a `description.yaml` file:

The `mount` attribute accepts an array of shared storage names to mount to your Python service.

### Create project with shared storage

Follow the guide [how to create a project based on description.yaml](/python/how-to/create#create-a-project-based-on-the-descriptionyaml) to deploy your Python service with shared storage.
