# This example will use spot instance type for all provisioned instances and enforces minValues to various keys where it is defined i.e
# at least 2 unique instance families from [c,m,r], 5 unique instance families [eg: "m5","m5d","m5dn","c5","c5d","c4" etc], 2 unique instance types [eg: "c5.2xlarge","c4.xlarge" etc] are required by the scheduler for the NodeClaim creation.
# This ensures minimum flexiblity required to schedule pods into spot nodes.
