unable to resize gke cluster

I have a GKE cluster with 2 nodes. A web application runs on them. I changed the .yaml file to have only one replica of the application.

Now I want to reduce the size of the cluster to 1 but the cluster size seems to stay two.

I have tried several options (editing default pool size via UI and also the following command - gcloud container clusters resize myclustername --node-pool mypoolname --num-nodes 1

But after the operation finishes, I still see two nodes.

gcloud container clusters resize myclustername --node-pool mypoolname --num-nodes 1
Pool [default-pool] for [...] will be resized to 1.

Do you want to continue (Y/n)?  Y

Maybe the auto-scaler immediately scaled up after you resized your cluster. Some research on logs could clarify the events triggered after the cluster resize.

I had to first disable auto scaling on the cluster.
