/*
Description:
- Here we will create an automation which picks up config.json, containing the blocks of nodes &
cluster info, create spec dynamically as per the struture of config.json and do imaging of nodes.
- You can download this config.json from install.nutanix.com or create one using the sample config.json given.
- Here we are following Bare metal workflow, imaging nodes using IPMI.
*/

/*
[IMPORTANT]
- Please note that this is just an example and the spec generated dynamically is only having minimal fields which are required
for imaging the blocks of nodes and creating cluster. You can add more fields as per the requirements.
- This example was created as per reference to config.json downloaded from install.nutanix.com -> Foundation Preconfiguration.
- Keep config.json in same directory where this .tf file is kept
*/
