Create shared storage service in Zerops

Zerops provides shared storage service that can be connected to runtime services. Shared storage enables your runtime service to share files between all containers of the same service or even among containers of different runtime services.

Connect a shared storage in Zerops GUI

Connect your .NET service directly when creating a new shared storage service. Just select your .NET service in the Share with Services block on the Add new shared storage service page.

To connect the existing shared storage to the .NET service, go to the shared storage service detail and select Shared storage connections. A list of all your current runtime services will be shown. Select a runtime service and the shared storage will be connected to the selected runtime.

Zerops will create a new folder /mnt/[shared storage name]`` in the runtime root folder. E.g. /mnt/teststoragefor ateststorage` shared storage. The content of this folder is shared among all containers of the runtime service you've selected. If you select multiple runtimes, the content of the folder will be shared among all containers of selected services.

Disconnect a shared storage in Zerops GUI

Go to the shared storage service detail and select Shared storage connections. A list of all your current runtime services will be shown. Switch off the toggle to disconnect the shared storage from the selected runtime.

Note

Your runtime service will be automatically restarted when a shared storage is disconnected.

Create .NET service with a shared storage using zCLI

zCLI is the Zerops command-line tool. To create a new .NET service via the command-line, follow these steps:

1. Install & setup zCLI
2. Create a project description file
3. Create a project with a .NET service and a shared storage

Create a project description file

Zerops uses a yaml format to describe the project infrastructure.

description.yml format

Read the basics how to define the .NET service using the description.yml.

Example with a shared storage

Create a directory my-project. Create an description.yml file inside the my-project directory with following content:

# basic project data
project:
  # project name
  name: my-project

  # optional: project description
  description: A project with a .NET and a shared storage

  # optional: project tags
  tags:
    - DEMO
    - ZEROPS

# array of project services
services:
  - # service name
    hostname: teststorage

    # shared storage service has no version
    type: shared-storage

    # mode: HA / NON_HA
    mode: NON_HA

  - # service name
    hostname: app

    # service type and version number in dotnet@6 format
    type: dotnet@6

    # defines the minimum number of containers for horizontal autoscaling. Max value = 6.
    minContainers: 2

    # defines the maximum number of containers for horizontal autoscaling. Max value = 6.
    maxContainers: 4

    # Mount the shared storage to the .NET service
    mount:
      - teststorage

The mount attribute accepts an array of shared storage names you want to mount to your runtime service.
