App engine instances increasing irrespective of app.yaml configuration

[Karthik Raja]

This is my app.yaml contents

runtime: nodejs

env: flex

env_variables:

  NODE_ENV : development

automatic_scaling:

  min_num_instances: 1

  max_num_instances: 1

  cool_down_period_sec: 120 # default value

But my current running instances are 2.How to reduce that to 1 ?

Just quickly looking at your projects I am only seeing a single version serving with 'max_num_instances: 1' and it does indeed only have one instance. 

Google Groups is meant for general product discussions and not for reporting Google-end issues. If you see this issue in the future it is recommended to file a Public Issue Tracker with more details such as your project number, version, yaml config, and dashboard screenshot showing the multiple instances.
