Extend Rally functionality
Add Deploy engines
Implementing your own deploy engines allows you to employ custom OpenStack platforms. You can see the list of already available Deploy engines here.
To implement a custom deploy engine, you need to create a subclass of rally.deploy.engine.EngineFactory and implement the __init__(), deploy() and cleanup() methods:
from rally.deploy import engine
from rally.serverprovider import provider
class MyEngine(engine.EngineFactory):
def __init__(self, task, config):
self.task = task
self._config = config
self._vms = []
provider_config = config['provider']
self._vm_provider = provider.ProviderFactory.get_provider(
provider_config)
# Perform further initialization here
def deploy(self):
self._vms = self._vm_provider.create_vms()
for vm in self._vms:
# Deploy OpenStack here
# Return the endpoints
return {
'identity': {
'url': 'http://$IDENTITY_HOST/' % identity_host,
'uri': 'http://$IDENTITY_HOST:5000/v2.0/' % identity_host,
'admin_username': '$ADMIN',
'admin_password': '$PASSWORD',
'admin_tenant_name': '$TENANT',
}
}
def cleanup(self):
# Cleanup the deployment here, e.g.
self._vm_provider.destroy_vms()
Add Server providers
