Autoscale using replicas

Autoscaling Harness Delegate using replicas for Helm chart deployments is a useful feature that can help ensure your deployments are executed efficiently, without downtime or resource overload.

To access the default Helm chart for the values.yaml file, go to Harness Delegate Helm chart.

note

You can also update the Harness Delegate YAML file in addition to the Helm chart.

To auto scale the delegate, do the following:

  1. In your values.yaml file, go to autoscaling parameters.

    autoscaling:
      enabled: false
      minReplicas: 1
      maxReplicas: 10
      targetCPUUtilizationPercentage: 80
      # targetMemoryUtilizationPercentage: 80

  2. Set enabled to true.

  3. Specify the minimum and maximum number of replicas you want to use in the minReplicas and maxReplicas parameters.

  4. To fine-tune your autoscaling, you can set the targetCPUUtilizationPercentage to add a new replica if CPU utilization exceeds this percentage.

  5. (Optional) Set the targetMemoryUtilizationPercentage to add a new replica if memory utilization exceeds this percentage.

  6. Save the file, and restart your pods.

When you create a deployment, Harness automatically spins up new replicas of your delegate as needed to ensure the deployment is completed.
