Swift is a very easy-to-use Object Storage client. It is sufficient to log into the Cloud@CNAF dashboard at tb-cloud-dashboard.cr.cnaf.infn.it and download the openrc file from the upper left drop down menu option:
If you need to install the swift client, just do pip install python-swiftclient. Then source the openrc file with your Openstack credentials and you are ready to use Swift client:
[ffornari@tb-cloud-ui test_clients]$ source admin-openrc-v3.sh
Please enter your OpenStack Password for project admin as user ffornari:
[ffornari@tb-cloud-ui test_clients]$ swift list
