Add a Kubernetes cluster

PDS supports Vanilla Kubernetes, AWS EKS, and Azure Kubernetes Service (AKS).

Prerequisites

• PDS account Admin privileges
• A supported Kubernetes cluster with Portworx Enterprise installed on it.
• Helm chart version 3.2.0 or newer

Prepare your cluster for installation

1. In the Settings → Deployment Targets page → select the Add Deployment Target button.

2. From the How to Add Deployment Targets window, copy the helm install command and paste it into a secure text editor.

   

   note

   Do not modify the helm install command.

Wait for the PDS agent to register the new deployment target in the control plane. Once successful, the status will show as a green check mark.

Prepare namespaces for deployment

After adding a target cluster to PDS, you must make any namespaces you intend to use with PDS available to it. Perform this task for each namespace you want to create and add:

1. Create a NAMESPACE environment variable with the namespace you want to create or add:

   export NAMESPACE=docs-test

2. Create the namespace, if it does not exist:

   kubectl create namespace $NAMESPACE

3. Label the namespace:

   kubectl label namespaces $NAMESPACE pds.portworx.com/available=true --overwrite=true

Once successful, the No namespaces available error message will disappear.

Disconnected deployment target

If a deployment target registration is unsuccessful, then the status will show as Disconnected. A deployment target becomes disconnected due to one or a combination of the following reasons:

• If Portworx is not installed, then the PDS agent fails to start.
• PDS agent fails to connect to the control plane.
• PDS agent fails to register the target cluster.
• Teleport agent fails to start.
• Teleport agent fails to connect to the control plane.
• Teleport agent fails to register the target cluster.
• Teleport agent fails to establish a secure reverse tunnel.
