Enabling Vitrage in DevStack
|
||||||
|
============================
|
||||||
|
|
||||||
|
1. Download DevStack::
|
||||||
|
|
||||||
|
git clone https://git.openstack.org/openstack-dev/devstack.git
|
||||||
|
cd devstack
|
||||||
|
|
||||||
|
2. Add this repo as an external repository in ``local.conf`` file::
|
||||||
|
|
||||||
|
[[local|localrc]]
|
||||||
|
enable_plugin vitrage https://git.openstack.org/openstack/vitrage
|
||||||
|
|
||||||
|
3. Run ``stack.sh``.
