This step explains how to set up your shell environment and create a Microsoft® Azure Kubernetes Service (AKS) cluster suitable for testing Apigee hybrid.

Set up your terminal shell

Be sure you have the Azure CLI (az) andkubectl tool installed in your local shell. The Azure CLI tool provides the primary command-line interface for Azure, andkubectl provides the primary command-line interface for running commands against Kubernetes clusters.

Create a resource group

Create a resource group either using Azure console or with the Azure CLI using the following command:

az group create --name my-hybrid-rg --location eastus

Create a virtual network

Create a virtual network with a non-conflicting CIDR range.

For example:

az network vnet create \ --namevnet-name \ --resource-groupmy-hybrid-rg \ --address-prefixesvnet-address-range \ --subnet-namevnet-subnet-name \ --subnet-prefixsubnet-address-range

az network vnet create \ --name my-hybrid-rg-vnet \ --resource-group my-hybrid-rg \ --address-prefixes 120.38.1.0/14 \ --subnet-name my-hybrid-rg-vnet-subnet \ --subnet-prefix 120.38.1.0/16

Where:

1. my-hybrid-rg is the name of the virtual network.
2. vnet-address-range is a list of address blocks reserved for this virtual network in CIDR notation.
3. vnet-subnet-name is the name of the subnet within the virtual network.
4. subnet-address-range is a list of address blocks reserved for this subnet in CIDR notation.

Create an AKS cluster

In this step, you will create an AKS cluster.

1. Open theMicrosoft® Azure Portal.
2. ClickKubernetes services.
3. Create a cluster with the following minimum configuration settings.Note: The configuration values shown below are for example purposes only. They are generally the default values and are suitable for testing purposes. It is up to you to decide how to configure your cluster to suit your requirements.

   Recommended minimum storage: Review the AKS disk specifications and choose a storage volume size based on your IOPs and cost requirements.

   You can see cluster configuration guidelines for Apigee hybrid inConfigure Cassandra for production andStorageClass configuration.

   Tab	Attribute	Value
   Basics	Subscription	Your subscription name
   	Resource group	The resource group you created previously
   	Region	The region you specified previously. For example: (US) East US
   	Kubernetes cluster name	The name of the cluster. For example:my-hybrid-aks-cluster
   	Kubernetes version	Choose version 1.16.x or a later version
   	DNS name prefix	The DNS name prefix. For example:my-hybrid-aks-cluster-dns
   	Node count	3
   	Node size	DS3 StandardNote: Using virtual CPUs less than 4 may result in the failure of Cassandra pod creation due to not enough CPUs. Storage will be provisioned using Kubernetes stateful dynamic provisioner
   Scale	Virtual nodes	Disabled
   	VM scale sets	Enabled
   Authentication	Enable RBAC	Yes
   	Service principal	Default
   Networking	HTTP application routing	No
   	Load balancer	Standard
   	Network configuration	Azure CNINote: For more information about planning your networking setup seePlan IP addressing for your cluster in the Azure documentation.
   	Virtual network	The virtual network name. You can select the virtual network you created previously, or create a new one by clicking theCreate new link. For example:my-hybrid-rg-vnet
   	Cluster subnet	Example:default (10.240.0.0/16)
   	Kubernetes service address range	The service address range. Be sure to use a non-competing address range. For example:10.0.0.0/16
   	Kubernetes DNS service IP address	For example:10.0.0.10
   	Docker Bridge address	For example:172.17.0.1/16
   Monitoring	Enable container monitoring	Yes
   	Log Analytics workspace	For example:DefaultWorkspace-66f9d75c-2cd9-47dd-ad0f-c43d888e9cef-EUS
   Tags		None

4. ClickReview and Create.
5. When the cluster creation completes, go to the next step.

Set cluster credentials

Add the Kubernetes cluster credentials for the newly created cluster using the following command if not already added:

az aks get-credentials --resource-group my-hybrid-rg --name my-hybrid-aks-cluster

Set the current context

Acontext is a group of access parameters. Each context contains a Kubernetes cluster, a user, and a namespace. The current context is the cluster that is currently the default forkubectl: allkubectl commands run against that cluster.

Make sure the current context is set to the cluster you just created using the following command:

kubectl config current-context my-hybrid-aks-cluster-context

If the context is not set to your cluster as expected, follow these steps to change it:

1. List all the contexts to determine which is thecurrent context. In the following example, the context is set to themy-hybrid-aks-ext01:

   kubectl config get-contextsCURRENT   NAME                            CLUSTER                                 AUTHINFO          my-hybrid-aks-cluster    my-hybrid-aks-cluster          clusterUser_my-hybrid-rg2_myhybrid-aks-cluster*         my-hybrid-aks-ext01      my-hybrid-aks-ext01            clusterUser_my-hybrid-rg_my-hybrid-aks-ext01

2. If necessary, set the current context to the cluster you just created (the cluster into which you intend to install Apigee hybrid). Assuming the previousget-contexts output, if the cluster name you created weremy-hybrid-aks-cluster, you would switch to themy-hybrid-aks-cluster context, as follows:

   kubectl config use-contextmy-hybrid-aks-cluster

   Wheremy-hybrid-aks-cluster is the name of the cluster context to switch to.

Summary

You now have a Kubernetes cluster running in AKS. Your shell environment is set up, and you are ready to install the Apigee hybrid runtime software on your local machine.
