[Bug 1515409] Re: swift proxy with ceilometer pipeline fails to start version conflict

[James Page]

The latest update to ceilometer changed:

python-neutronclient<2.5.0,>=2.3.11

to

python-neutronclient<2.5.0,>=2.4.0

that should not have happened; looking into it now

  If i pull ceilometer out of the pipeline swift-init proxy start processes without issue.  If I install the updated dependancies with pip I am able to start the proxy server without issues:
  pip install python-neutronclient==2.4.0
  pip install python-ceilometerclient==1.1.1
  pip install oslo.concurrency==1.8.2

  after updating those packages I am able to start the swift-proxy server.  Can these dependencies be reviewed / updated in the cloud archive?
  Thanks,
  -Matt
