Node.js Instance Configuration

[Jagath Weerasinghe]

Hi All, 

We run a node.js AppEngine module with the following configuration:

runtime: nodejs16
env: standard
service: app
instance_class: F4
automatic_scaling:
max_instances: 5
min_instances: 0
max_idle_instances: 1
min_idle_instances: 1

We expect this config to see an idle instance always running, as we observe with java8 app engine modules. But with node.js, when there is no traffic instance count goes to 0. 

Please let me know what I am missing here. 

Thanks,

Jagath
