Create shared storage service for Python

Zerops provides shared storage service 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
2. Create a project description file
3. Create the project

Create project description file

Zerops uses YAML format to describe project infrastructure. Read the basics about defining Python services in description.yaml.

Example with shared storage

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

# Basic project data
project:
  name: my-project
  description: A project with Python and shared storage
  tags:
    - DEMO
    - ZEROPS

# Project services
services:
  - # Shared storage service
    hostname: teststorage
    type: shared-storage
    mode: NON_HA

  - # Python service
    hostname: app
    type: python@3.12
    minContainers: 1
    maxContainers: 3

    # Mount the shared storage
    mount:
      - teststorage

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 to deploy your Python service with shared storage.
