Deploy Storage Autoscaling

Prev Next

This topic describes how to deploy and configure Storage Autoscaling. Installation is based on a Helm chart published in github repo.

Prerequisites

  • A running EKS cluster, v1.7 or later, with the EBS CSI add-on installed, with one storage class defined

  • Kubectl is installed

  • Access to the Zesty platform
    For more information, contact Customer Support.

  • The Zesty API key
    For more information, see Find your Zesty API key.

  • Outbound HTTPS communication from cluster nodes

  • The AWS account ID of the cluster on which Storage Autoscaling is being installed
    Before deploying, share this ID with a Zesty Customer Support representative.
    Note that this ID may be different than the one from the Management account (formerly known as Master Payer account).

To install Storage Autoscaling:

  1. Add or update the Zesty repository to your Helm client:

    • To add the repository:

      helm repo add zestyrepo https://zesty-co.github.io/zesty-helm

    • If the repository is already configured, update it:

      helm repo update

  2. Install the Zesty PVC Helm chart:

    # Minimal

helm install zesty-pvc --set agentManager.apiKey=<API_KEY> zestyrepo/zesty

# With advanced options

helm install zesty-pvc --set agentManager.apiKey=<API_KEY> /

[--set agentManager.prometheusExporter.port=<PORT>] /

[--set "tolerations[0].operator=<VALUE>,tolerations[0].effect=<VALUE>,tolerations[0].key=<KEY>"] / 

[--set "nodeSelector.<KEY>=<VALUE>"] / 

[--set storageClassName=<storageClass name>] / 

[--namespace <Namespace>] /

    The following table describes the popular command arguments. For the full arguments list, see the Helm chart at https://zesty-co.github.io/zesty-helm/.

    Argument

    Mandatory

    Description

    agentManager.apiKey=<API_KEY>

    Yes

    Enter the Zesty-provided API Key. You can also enter the API key as a secret, as described in the Helm chart. To get your API key, see Find your Zesty API key.

    agentManager.prometheusExporter.port=<PORT>

    No

    Enables the Prometheus exported for Storage Autoscaling solution. We recommend using the Prometheus default port, 8443.

    agentManager.prometheusExporter.podMonitor.enabled=<bool>

    No

    Enables Prometheus autodiscovery of Zesty metrics.

    "tolerations[0].operator=<VALUE>,tolerations[0].effect=<VALUE>,tolerations[0].key=<KEY>"

    No

    Configures tolerations roles. You can set as many as needed while making sure to increase the list index number.

    "nodeSelector.<KEY>=<VALUE>"

    No

    Configures on which nodes Storage Autoscaling is allowed. Use quotes to avoid shell issues.

    For example, “nodeSelector.kubernetes\.io/os=linux”. Note the ‘\’ before the “.io” in the node selector key that is used as an escape character.

    --set storageClassName=<storageClass name>

    No

    Configures which storage class Storage Autoscaling will use to provision new disks. If this is not set, the first one found with EBS CSI provisioner (ebs.csi.aws.com) is used.

    --namespace <Namespace>

    No

    Specifies on which namespace Storage Autoscaling resources will be deployed.
