Hi,

I'm trying to update a few things in a Stein cluster and while building some kolla containers, I get the following error when building the base container:

INFO:kolla.common.utils.openstack-base:Step 4/8 : RUN curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py     && python get-pip.py     && rm get-pip.py

Any ideas as to where the issue is?  Is this a pip installer bug?
