This section describes the basic requirements for setting up a Google Kubernetes Engine (GKE) cluster suitable for an Apigee hybrid production installation.
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
gcloud container get-server-config 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
|
| 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
|
| Minimum number of nodes | 3 (1 per zone) |
| Machine type | N1-standard-4 (Standard machine type with 4 vCPUs, 15 GB of memory) |
