Why are 4 instances are created instead of just 1?

[carlus]

Hi,

this is my app.yaml

runtime: nodejs20
instance_class: B2
manual_scaling:
instances: 1

but in GCP console i can see 4 instances are created. What am i doing wrong?

This sounds very similar to another thread on here, and is quite likely related to an issue on our end that we're working on resolving.
