Installing on Azure Kubernetes Service (AKS)
Published 18 January 2022
This page provides step-by-step instructions on how to create AKS infrastructure and deploy the Redgate Clone solution onto it.
Contents
Create Kubernetes service
On the landing page of the Azure Portal, click on "Create a resource". Search for "Azure Kubernetes Service (AKS)".
Click on "Azure Kubernetes Service (AKS)" and then click "Create".
Select the Azure subscription you want to store the Kubernetes service in and create a new resource group for it.
Configuration
You'll need to configure the AKS instance. We have some required settings here that differ from the defaults and are necessary for Redgate Clone to function correctly.
After changing settings from the four tabs shown below, click on "Review + create" and Azure will start creating your cluster. Wait for the creation process to complete before continuing.
| Setting | Expected value |
|---|---|
| Subscription | The Azure subscription you want to place the resource in |
| Resource group | We recommend creating a new one for this service |
| Kubernetes cluster name | This will name the Azure resource itself. "rgclone" is fine |
| Kubernetes version | 1.29.0 |
| Automatic upgrade | Disabled |
| Setting | Expected value |
|---|---|
| Container networking configuration | Choose Azure CNI. NOTE: There's a new version of the Azure CNI called Azure CNI Overlay. We do not support the overlay version. |
By default AKS uses two node pools (agentpool and userpool). We recommend leaving the agentpool node pool as default, and configuring two user mode node pools for the Redgate Clone application to use: Redgate Clone can be installed in just a single node pool. Leave the agentpool as default and configure userpool as follows:
| Pool | rg-infra-pool |
|---|---|
| Node size | E8s_v5 (Recommended minimum) |
| Scale method | Manual |
| Node count | 1 |
| Max pods per node | 250 |
| Labels | redgate.com/infrastructure-node=true redgate.com/cloning-node=true redgate.com/cloning-mssql-node=true redgate.com/cloning-oracle-node=true |
| Pool | rg-cloning-pool |
|---|---|
| Setting | Expected value |
|---|---|
| Azure Monitor | Off |
Install Redgate Clone to the AKS instance
Locate the "Kubernetes service" in the resource group created earlier.
You will need to complete some of the following steps in a bash shell. On Windows, please use WSL.
Connect to the AKS instance
From the Kubernetes service, there are instructions on how to connect that appear when you press the "Connect" button in the command bar at the top of the page. Follow the instructions for the "Azure CLI".
Verify the connection is working with the command:
kubectl get nodes
You should see output similar to this:
Install Redgate Clone
Execute the following command in a bash shell.
curl https://kots.io/install | bash
Accept the default installation directory.
Execute the following command:
kubectl kots install cloning-capability-app
When prompted, enter "default" as the namespace to deploy to.
When prompted, choose and enter a password to use for connecting to the admin console. Remember this for later.
Configure Redgate Clone
Visit the admin console in a browser to continue setup at the location given by the previous command.
Continue as per the instructions given in the installation quick start guide, but with the following AKS-specific configuration values.
| Setting | Expected value |
|---|---|
| Disk size | Size in GiB of the disk for data images and data containers. Default value is 100 GiB |
| Azure DNS Label | Must be unique to the Azure location of your AKS instance. To learn more visit the Microsoft learn page on the DNS label. |
