Documentation

For help installing and using dcc, please visit the online documentation.

Installation

dcc has the following system requirements:

• Python 3.8 or later
• kinit and klist provided as part of Kerberos

Most users will find it easiest to use one of the reference software environments provided by IGWN. The igwn-py38 environment, for example, provides the required dependencies. If you choose to manage system dependencies yourself, ensure you have the relevant Kerberos packages above (provided on Linux by e.g. krb5-user on Debian derivatives or krb5-workstation on Red Hat derivatives).

Once you have the required system dependencies, you can install dcc using your favourite Python package manager, e.g. using pip:

$ pip install dcc
