Python-requests 2.8.x not compatible with docker-compose 1.2.0.

This document (7017258) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12 (SLES 12)
SUSE Linux Enterprise Server 12 Service Pack 1 (SLES 12 SP1)
Docker

Situation

When updating SUSE Linux Enterprise Server 12 (containers module), the python-requests package is updated to version 2.8.x.

Following the update, it is no longer possible to start docker-compose.

Resolution

Interim solution until this will be resolved in code :

Downgrade the problematic python-requests version to the 2.3 version available in the Pool repository, for SLES 12 it is located in "SLES12-Pool" and for SLES 12 SP1 in "SLES12-SP1-Pool".

Additional Information

The following traceback is observed for Python version 2.8.1 when starting 'docker-compose' :
