Description: Setting up and configuring a multi region cockroach cluster on Azure AKS Tags: Azure
-
Create a Resource Group for the project
az group create --name $rg --location $loc1
-
Networking configuration
In order to enable VPC peering between the regions, the CIDR blocks of the VPCs must not overlap. This value cannot change once the cluster has been created, so be sure that your IP ranges do not overlap.
-
Create vnets for all Regions
az network vnet create -g $rg -n crdb-$loc1 --location $loc1 --address-prefix $clus1_vnet_address_space \ --subnet-name crdb-$loc1-sub1 --subnet-prefix $clus1_subnet
-
-
Create the Kubernetes clusters in each region
-
To get SubnetID
loc1subid=$(az network vnet subnet list --resource-group $rg --vnet-name crdb-$loc1 | jq -r '.[].id') -
Create K8s Clusters in each region
az aks create \ --name $clus1 \ --resource-group $rg \ --network-plugin azure \ --zones 1 2 3 \ --vnet-subnet-id $loc1subid \ --node-vm-size $vm_type \ --node-count $n_nodes \ --location $loc1
-
To Configure Kubectl context use
az aks get-credentials --name $clus1 --resource-group $rg
