This topic describes how to deploy and configure Zesty Disk for K8s. 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, see Access the Zesty platform/The Zesty API key
For more information, see Find your Zesty API key.Outbound HTTPS communication from cluster nodes
To install Zesty Disk for K8s:
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
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 Zesty Disk for K8s 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 Zesty Disk for K8s 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 Zesty Disk for K8s 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 Zesty Disk for K8s resources will be deployed. |
