Add additional nodes to your Container Engine cluster using the following command:

gcloud container clusters resize CLUSTER_NAME --size 10

Add a tag to the instances in the cluster with the following command:

gcloud compute instances add-tags INSTANCE --tags enable --autoscaling max-nodes-10

Update the existing Container Engine cluster with the following command:

gcloud alpha container clusters update mycluster --enable-autoscaling --min-nodes=1 --max-nodes=10

Create a new Container Engine cluster with the following command:

gcloud alpha container clusters create mycluster --enable-autocaling --min-nodes=1 --max-nodes=10

and redeploy your application.
