===========================
|
||||
Enabling Bilean in DevStack
|
||||
===========================
|
||||
|
||||
1. Download DevStack:
|
||||
git clone https://git.openstack.org/openstack-dev/devstack
|
||||
cd devstack
|
||||
|
||||
2. Add this repo as an external repository::
|
||||
|
||||
cat > /opt/stack/devstack/local.conf << END
|
||||
[[local|localrc]]
|
||||
enable_plugin bilean https://github.com/openstack/bilean master
|
||||
END
|
||||
|
||||
3. Add Plugin Configuration Hooks
|
||||
|
||||
Bilean service is driven using a plugin mechanism for integrating to other
|
||||
services. Each integrated service may require additional configuration
|
||||
settings. For example, typically, you will need to add the
|
||||
``billing_notifications`` notification topic to each service's configuration.
|
||||
|
||||
4. Then run devstack normally::
|
||||
|
||||
cd /opt/stack/devstack
|
||||
./stack.sh
