Proof of concept playbooks and roles to take a simple inventory and generate a larger inventory that can be leveraged by the ansible-netplan role.

Network configuration can be applied via ansible once a machine is bootstrapped with bifrost.

installation

The installation process consists of cloning the 'netplanner' repo and bringing in a dependency repo: ansible-netplan.

git clone https://github.com/busterswt/netplanner/ ~/netplanner
git clone https://github.com/mrlesmithjr/ansible-netplan ~/netplanner/roles/ansible-netplan

inventory

A simple inventory (simple_inventory) should be maintained that contains relevant interface names and IP addresses, routes, etc to be applied.

overrides

Most of the network configuration assumes a homogenous environment, and those network values can be defined in the overrides.yml file. Any host specific changes can be implemented in the respective host_vars file.

usage

To apply network configurations to hosts in the inventory, run the following:

ansible-playbook -i simple_inventory site.yml -e @overrides.yml

todo (notes to myself)

• Remove existing netplan configuration file(s) before performing netplan apply
