libdc3 0.5.0

The python library for dc3 and central DC shifters

libdc3

Library designed to implement all operations needed for DC3 application and at the same time be human-usable through python scripts or notebooks.

Installation

To install libdc3, simply

$ pip install libdc3

Environment variables

This library depends heavily on runregistry python package, so it is needed to set SSO_CLIENT_ID and SSO_CLIENT_SECRET in your environment.

The interface with brilcalc is done via SSH or standard python subprocess if brilconda environment is available under the /cvmfs location. If executing in an environment without brilconda, you need to configure the dc3_config object with your LXPlus credentials (recommended via environment variables).

Last but not least, in order to successfully communicate with DQMGUI and T0 endpoints a valid CERN Grid certificate is needed. Again, the dc3_config object should be configured with paths to the grid certificated and key (that should be opened).

SWAN setup

1. Configure your SWAN environment using Software stack 105a and select the option Use Python packages installed on CERNBox
2. Create a SWAN project with any name you like and upload all example notebooks to it
3. Open SWAN terminal and create a .env file under your project directory and add the following variables: SSO_CLIENT_ID, SSO_CLIENT_SECRET, AUTH_CERT, AUTH_CERT_KEY
4. On any notebook, create a new cell and add pip install libdc3.
