Note: These scripts are specific to an Azure-based installation of Domino Data Lab. The scripts should be able to be adapted to any cloud provider, but are only guaranteed to work within Azure.

Purpose

These scripts and yaml pipelines can be used to automate the scaling of compute resources for a Domino Data Lab implementation. Doing so may save your organization's resources during idle times in the system.

Prerequisites

• A Domino Data Lab installation using Azure cloud resources
• Access to the Azure resources used for the installation of Domino Data Lab
• A Service Principal (or equivalent) has been provisioned in your Azure tenancy with permissions to modify your Domino installation's node pools in AKS
• An Azure Pipeline Library Variable Group with access to the Service Principal secret
• The scaleDownDomino.sh and scaleUpDomino.sh scripts are both executable (if not, run chmod +x <filename> from the project directory in a terminal)

Usage

• Replace the values in all files surrounded by <> with your organization's information
• Create two Azure pipelines using the system-scale-up and system-scale-down.yaml files
• Enable variable group access to the pipelines for the group containing the Service Principal's secrets
• Configure the CronJob values to suit your organization's specific timing needs
  • for example, the default schedule is set to run the scale-down at 1 AM, UTC (9 PM EST), Tuesday-Saturday. cron: "0 1 * * Tue,Wed,Thu,Fri,Sat"
• Determine the extent of how you would like to scale your Domino system
  • The example in this project assumes a smaller implementation. Adjust the node pool numbers based on your organizational needs.

Note: Your system will still require the Azure default system node pool even after you have scaled down your domino platform and compute node pools. From Azure's AKS documentation: "Every AKS cluster must contain at least one system node pool with at least two nodes."
