Description Britt Houser 2014-08-01 14:10:11 UTC
Description of problem:

When configuring PackStack, one of the valid mechanism drivers is the cisco_nexus driver.  All the prerequisites are available in the rhel-7-server-rpms or rhel-7-server-openstack-5.0-rpms repos except ncclient.  Prerequisites can be found here:


Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. subscription-manager repos --disable=*
2. subscription-manager repos --enable=rhel-7-server-rpms
3. subscription-manager repos --enable=rhel-7-server-openstack-5.0-rpms
4. yum install ncclient

Actual results:

ncclient not found

Expected results:

ncclient installed

I've checked the link. Cisco asks us to ship some patched version of ncclient to be able to use the plugin. Doesn't it mean Cisco should first make sure that upstream packages depend on the library (by putting it into requirements.txt)? We should go that route instead of shipping some untrusted code from github in a package.

Britt, can I ask you to work on getting upstream dependency straight?

Comment 3 Ihar Hrachyshka 2014-08-12 14:28:33 UTC
FYI: I've sent an email to clarify the status of the dependency: http://lists.openstack.org/pipermail/openstack-dev/2014-August/042724.html

Comment 4 Britt Houser 2014-08-14 20:20:34 UTC
Ihar - looks like your thread has uncovered that in Juno time frame, the upstream version of ncclient will work.  So for OSP6, it will make sense to include the upstream version.  But for Icehouse and before, Pradeep has already provided spec file:

RPM Spec: https://github.com/CiscoSystems/ncclient-spec
SOURCE:   https://github.com/CiscoSystems/ncclient
I have the packages built here for reference

I believe these are already in the build system.  Can we get the package built based on these spec included in the OSP5 repo?

Comment 5 Ihar Hrachyshka 2014-08-18 12:05:43 UTC
@Brit, Red Hat will not ship custom code from github that does not follow usual procedures like peer review or CI. It's great that Cisco plugin is now able to use stock ncclient in Juno. Once we get that in Icehouse, we may reconsider making Cisco plugin depending on it. If you want users of the plugin not to be forced to go thru checking out the code from github, you can deliver your custom RPM to them.

Also, I'm currently working on setting dependencies straight in upstream, so that plugin do not depend on any modules implicitly avoiding requirements.txt file. But this is a long term thing and is not applicable to RHOSP5.

Comment 6 Lon Hohberger 2014-08-27 21:30:48 UTC

0.4.1 looks good.

Comment 7 Joe Donohue 2014-08-27 21:32:39 UTC
Reopening for 0.4.1 version.

Comment 8 Ihar Hrachyshka 2014-09-15 14:10:03 UTC
@Lon, Cisco plugin was not compatible to u/s ncclient till very recently in Juno. If we want to use the package from PyPI, we should first make sure we have the needed patches in Icehouse to work with it.

Comment 9 Ihar Hrachyshka 2014-09-15 15:25:31 UTC
I've requested a backport for Icehouse for the plugin to use upstream ncclient. Also, I went with preparing a SPEC to package it: http://people.redhat.com/~ihrachys/python-ncclient.spec There is one problem that is currently blocking review for the package for Fedora Rawhide: license file is missing from the package provided at PyPI. I've contacted its owner thru email to add the missing file to the package.

Comment 10 Ihar Hrachyshka 2014-10-08 09:09:08 UTC
Quoting the maintainer of the upstream library, "Rel. 0.4.2 just hit the road and  it includes the missing LICENSE file." So we should be ok now with building an upstream package for Fedora.

Comment 13 Ihar Hrachyshka 2014-12-04 13:40:43 UTC
I've requested a Fedora package at: https://bugzilla.redhat.com/show_bug.cgi?id=1170629

Comment 14 Ihar Hrachyshka 2014-12-05 14:53:15 UTC
Sorry, closed wrong bug.

Comment 16 Ihar Hrachyshka 2014-12-05 16:59:17 UTC
Also made openstack-neutron-2014.2.1-2.el7ost depend on python-ncclient for ml2, cisco, and brocade plugins that use the module.
