Do we need to change overrides.yml file after we added additional nodes to apigee-runtime node pool?

Hi,

There is a example overrides.yml file on the apigee documentation.

The question is

"I would like to add five more nodes to apigee-runtime node pool. So the total will be 8 nodes in that node pool. So, do I need to change any config in overrides.yml file to reflect the node pool changes?"

Thanks.

Yeah but no but yeah

So just adding nodes alone doesn't warrant changing the overrides config to my knowledge.

However, I'm assuming there's some reason why you want to add more nodes eg support additional environments, or further scaling of runtime or other components - so these types of changes will need to be applied in the overrides.

If scaling is of interest check for the replicaCount attributes, and there's some more guidance here

For adding environments you can refer to here https://cloud.google.com/apigee/docs/hybrid/v1.9/environment-create

Thanks a lot for the answer @dknezic .

Yes. I am scaling to support more TPS. Here are my follow-up questions.

1. The default ReplicaCount is calculated base on 3-nodes apigee-runtime node pool. Am I right?

2. If I add more nodes to apigee-runtime node pool to support more TPS, I need to increase ReplicaCount of runtime. Am I right?

Thanks
