Re: [Xen-users] XCP & Openstack

[Andrew Eross <eross@xxxxxxxxxxxx>]

Hi Todd,

If I'm parsing that script below correctly --

For every time someone is making a git commit, it's grabbing the UUID for each commit and generating an RPM for that version and uploading it.

Hmmm, dare I ask if there is something like a single place to grab a reasonably stable release of plugins that is tied to a particular XCP or OS version?

Yep, totally hear you -- my goal is to do a dual-node install (1 controller + multiple compute nodes) by creating a Chef recipe based on the existing xenserver recipes in the openstack cookbook.

Cheers,

Andrew

This is currently running with a Jenkins script on each commit:

cd plugins/xenserver/xenapi/contrib
export VER=`git rev-parse HEAD`
perl -i -pe 's/^(Release:\s+)(.+)/$1$ENV{VER}/'
rpmbuild/SPECS/openstack-xen-plugins.spec
./build-rpm.sh
mkdir -p openstack-xen-plugins
cp rpmbuild/RPMS/noarch/*.rpm openstack-xen-plugins
createrepo openstack-xen-plugins
scp -r openstack-xen-plugins
deshantm@xxxxxxxxxxx:/data/files/downloads.xen.org/XCP/openstack

In production you'd want to run this script for a particular release
of your OpenStack deployment so that it is in sync.

They are good for setting up a development environment, but for
deploying OpenStack you should really use configuration management
(Puppet, Chef, Crowbar, etc.)

Probably not, but you should encapsulate the best practices with the
e.g. chef scripts, etc.

Cheers,
Todd
