Here is the example repo structure
```
.
|-- controller_configs
| `-- glance-api.conf
|-- node_1_configs
| `-- nova.conf
|-- nova.conf
|-- overrides.yaml
`-- tools
`-- show-config-for.py
|-- cluster.yaml
|-- nodes
| `-- node-1.domain.local.yaml
`-- roles
|-- compute.yaml
|-- controller.yaml
`-- primary-controller.yaml
```
There are three levels of configuration: Global, Role, Node. Each level has higher priority in terms
There are three levels of configuration: Cluster, Role, Node. Each level has higher priority in terms
of configuration parameters.
* Global - configuration parameters from all configs from this level will be applied to all nodes
* Cluster - configuration parameters from all configs from this level will be applied to all nodes
in environment.
* Role - configuration parameters from all configs from this level will be applied to nodes with a
particular role. Parameters from this level will override parameters from Global level
* Node - configuration parameters from all configs from this level will be applied to node with a
particular id. Parameters from this level will override parameters from Global and Role levels
For example we have ```nova.conf``` file with ```debug = True``` in Global level and ```nova.conf```
with ```debug = False``` in Role level. Resulting configuration will be:
For example we have following contents of the files
```
[DEFAULT]
debug = False
# cat cluster.yaml
configuration:
nova_config:
'DEFAULT/nova_test':
value: cluster_param
'DEFAULT/another_param':
value: another_param_value
# cat roles/primary-controller.yaml
configuration:
nova_config:
'DEFAULT/nova_test':
value: controller_param
```
Configuration files for Global level should be placed in repo root. Role and Node levels should be
described in overrides.yaml placed in repo root directory using following format
Resulting configuration Hash will be:
```
nodes:
'<node_id>': '<directory_name>'
roles:
'<role_name>': '<directory_name>'
configuration:
nova_config:
'DEFAULT/nova_test':
value: controller_param
'DEFAULT/another_param':
value: another_param_value
```
Example overrides.yaml
```
nodes:
'1': node_1_configs
'2': node_2_configs
roles:
'cinder': 'cinder_configs'
'compute': 'compute_configs'
'controller': 'controller_configs'
'primary-controller': 'controller_configs'
```
Configuration files for Role and Node levels should be placed in corresponding directory described
in overrides.yaml
### Audit and enforcement
This feature enables the operator to audit the changes made to the environment as well as enforce
