# config_drift_role
Ansible's role for preserve configuration applied to interfaces using on-box templating `source template`, by collecting the configuration converting it to structured data as source of truth, followed by negation of the source templates per interface and re-applying the configuration back to the device using resource modules.
Helps migrating on box l2 & interface configuration from on box templates based configuration.
## Execution steps
### Part 1
- Fetching `derived-config` configuration.
- Feed it to the parsed state of ios.interfaces and ios.l2_interfaces resource module.
- Store the source of truth generated in corresponding yaml files.
### Part 2
- Identify the interfaces using templates using `running-config`.
- Generate a template-based configuration for the interfaces using templates.
- Negate the templates per interface using the config generated.
### Part 3
- Apply back the configuration with ios.interfaces and ios.l2_interfaces resource module.
## Example Playbook
file: play.yml
```
tasks:
- name: Build source of truth based on derived config
ansible.builtin.include_role: &ref_role
name: config_drift_role
vars:
action: build source of truth
- name: Negate existing source templates per interface
ansible.builtin.include_role: *ref_role
vars:
action: negate existing templates
- name: Apply back configuration with resource module
ansible.builtin.include_role: *ref_role
vars:
action: apply back configuration
```
