If these parameters are set both through `node_spec` and globally through `node_*`, `node_spec` values will have precedence. As a minimum, each node role needs to have the following inputs set in `node_spec`: `num_vcpu` (VM number of vCPUs), `memory_gb` (VM memory in GB) and `disk_gb` (VM disk size in GB) - all other values can be inherited from global variables.
