Generic Installation Notes

All eXtreme-DataCloud products are distributed from standard OperatingSystems (OS) repositories and DockerHub registry.

The packages repositories have the following structure:

All signed packages use the INDIGO - DataCloud gpg key. The public key can be downloaded from here, and the fingerprint from here.

It is strongly recommended the use of the lastest version of the xdc-release packages containing the public key and the YUM and APT repository files.

On the DockerHub Registry, eXtreme-DataCloud uses the INDIGO - DataCloud and XDC Organizations:

Containers present in those repositories and released in XDC-1 are tagged with “XDC-1” tag and signed, leveraging the Docker’s trust features so that users can pull trusted images.

To understand how to install and configure XDC-1/Pulsar services and components either refer to the Generic Installation Notes chapter or to each individual product documentation.


XDC-1 software can be downloaded from eXtreme-DataCloud repositories.
