DataHub OneProvider

Documentation for installation/configuration of OneProvider to join EGI DataHub spaces

This documentation covers how to install and configure a OneData OneProvider in order to join a new or existing EGI DataHub space. In particular two types of installations are available, depending if the provider wants to support the space with an empty storage or if existing data should be exposed via the Oneprovider.

Requirements for production installation

  • Oneprovider
    • RAM: 32GB
    • CPU: 8 vCPU
    • Disk: 50GB SSD
    • To be adjusted for the dataset and usage scenario
  • For high Input/Output operations per second (IOPS)
    • High performance backend storage (CEPH)
    • Low latency network

Network Requirements

  • The following ports need to be open on the local and site firewall:
    • 80, 443, 9443, 6665 (for data transfer)

Installation and attach empty storage to the EGI DataHub

The installation of a new Oneprovider is performed using the onedatify installation script which will setup the components using Docker and Docker-compose.

This simple installation script can be generated from the EGI DataHub interface.

Firstly, you need to login to the EGI DataHub and using the Data menu you either select an existing space or create a new one.

Secondly, you can select on the space menu the Providers section and click on the Add Support button on the top right corner.


You should then select on the page the tab: Deploy your own provider

In order to obtain the PROVIDER_REGISTRATION_TOKEN that is part of the preconfigured command, you need to contact the EGI HelpDesk, selecting DataHub as support unit.

Please include in the request the following info:

  • Use case for the installation of a Oneprovider connected to the EGI DataHub
  • Name and the email of the Oneprovider admin
  • domain name of the Oneprovider


Run the command on the host

With the obtained PROVIDER_REGISTRATION_TOKEN, paste the copied command in the terminal on the Oneprovider machine as superuser.

If necessary, the Onedatify script will ask for permission to install all necessary dependencies including Docker and Docker Compose.

After the dependency installation is complete, the script will ask several questions and suggest default settings:


The progress can be monitored on a separate terminal using the following command:

onedatify logs

After the deployment is complete, a message will be shown, including connection details for the administration panel of the Oneprovider:


This administration panel at port 9443 can be used to administer the Oneprovider.

Installation and expose existing data to the EGI DataHub

The installation of a new OneProvider to expose existing datasets to an EGI DataHub space is similar to the installation with an empty storage.

When adding support to an existing or new space you should select from the EGI DataHub user interface the tab : Expose Existing dataset.

Please refer to the steps described in the Installation and attach empty storage to the EGI DataHub section to request a PROVIDER_REGISTRATION_TOKEN.

Once obtained, you will have to copy the command already configured with the correct parameters for the Onezone ( and the space to join.


Run the command on the host

Paste the copied command in the terminal on the Oneprovider machine as superuser, and follow the instructions as for the case of an empty storage.

The only difference is that at the end of the installation and configuration process the existing files will be automatically imported to the OneProvider.

You can monitor the import activity from the administration panel at port 9443.
