Solution

Select the node size which fits in the following formulae for max pods per node value, and this value should be greater than the value that comes by the following formulae.

1. For 2 CPU's and 8 GB RAM node configuration:
    CPU: More than 2 CPU's
    RAM per node: 8GB
    Maximum pods per node: 6 (system) + 4 (Static pods) + 8*2=16 (Dynamic pods) = 26 or more
    Autoscaling enabled, with minimum=1, maximim=3

2. For 2/4/6 CPU's and 16 GB node configuration:
    CPU per node: More than 2/4/6 CPU's
    RAM per node: 16 GB
    Maximum pods per node: 6 (system) + 4 (Static pods) + 16*2=32 (Dynamic pods) = 42 or more 
    Autoscaling enabled, with minimum=1, maximum=3
