Automate 2 Tricks

list_nodes_with_updated_resources.sh

#!/bin/bash
#
# Author::  Salim Afiune <[email protected]>
# Purpose:: List all nodes from an Automate 2 server that their last chef-client run updated one or more resources
#
# Requirements:
#     * curl      - https://curl.haxx.se/download.html
#     * jq        - https://stedolan.github.io/jq/
#     * API token - https://automate.chef.io/docs/api-tokens/#creating-an-admin-api-token
#
# Usage:: Update the script with your automate fqdn and a valid admin token, then execute the script.
#         Pass the parameter 'all' to list all nodes regardless if they have updated resources or not.
#
#         $ ./list_nodes_with_updated_resources.sh all
#                    Node ID         | Updated Resources | Node Name
