This section describes the basic requirements for setting up a Google Kubernetes Engine (GKE) cluster suitable for an Apigee hybrid production installation.

A production cluster can consume significant resources because it includes more nodes and larger virtual machine configurations than a non-production setup. Also, a production cluster might be hosted in multiple zones and regions worldwide.

Creating the cluster

For information about creating GKE clusters, see Creating a cluster in the GKE documentation.

Production cluster requirements

Follow these requirements when creating your production cluster:

Software versions

Requirement	Value
Kubernetes version	Version 1.14.x or later You can find the supported Kubernetes cluster versions by issuing the following command: gcloud container get-server-config Supported versions are returned under the validMasterVersions: heading.
kubectl version	Version 1.14.x or later. See Install and Set Up kubectl.

Cluster template configuration

Choose these template configuration options for your production GKE cluster:

Configuration	Value
Cluster template	Standard cluster
Location type	Regional (recommended)
Availability zones	3
Autoscaling	Enable autoscaling for your nodes, with the minimum and maximum number of instances set to the same number. GKE will give you a warning about setting the values to the same number. You can ignore this warning. For more information, see Scale and autoscale hybrid services.
Storage	Storage is provisioned dynamically using the StatefulSet dynamic provisioner.

Node requirements

A node pool is a group of nodes within a cluster that all have the same configuration. By default, you must configure two node pools in your cluster -- one for the stateful Cassandra pods and one for the rest of the pods, which are stateless. Configure these two node pools as described below:

Stateful node pool configuration

Configure a stateful node pool as follows:

Configuration	Value
Name	apigee-data NOTE: You must use the name apigee-data. If you want to use another node pool name, see Configure dedicated node pools.
Minimum number of nodes	3
Machine type	N1-standard-8 (Standard machine type with 8 vCPUs, 30 GB of memory)
Storage	Storage will be provisioned dynamically using StatefulSet dynamic provisioner

Stateless node pool configuration

Configure a stateless node pool as follows:

Configuration	Value
Name	apigee-runtime NOTE: You must use the name apigee-runtime. If you want to use another node pool name, see Configure dedicated node pools.
Minimum number of nodes	3 (1 per zone)
Machine type	N1-standard-4 (Standard machine type with 4 vCPUs, 15 GB of memory)
