Switch to pay-as-you-go billing on an existing Kubernetes cluster

If you already set up your cluster using any of the paid or free Portworx licenses (trial, extended, traditional), you can switch to pay-as-you-go billing by acquiring a pay-as-you-go account key from Portworx, Inc. support and performing the steps in this article.

Prerequisites

• A pay-as-you-go account key, acquired by contacting Portworx, Inc. support.

Enable pay-as-you-go billing

1. Create a Kubernetes secret and place your pay-as-you-go account key into it:

   kubectl create secret generic px-saas-key --from-literal=account-key=<PAY-AS-YOU-GO-KEY> -n kube-system

2. Patch the pay-as-you-go secret into your cluster. Follow the steps appropriate for your cluster’s install method:

   • Operator-based installations

     From the master node in your cluster, store the stc as an environment variable:

     stc=$(kubectl get stc -n kube-system | awk '{if(NR>1)print $1}')

     Patch the stc using the secret you created in step 1:

     kubectl  patch stc $stc  --type='json' -p='[{"op": "add", "path": "/spec/env/0","value": {"name": "SAAS_ACCOUNT_KEY_STRING", "valueFrom":{"secretKeyRef":{"key": "account-key", "name": "px-saas-key"}}}}]' -n kube-system

   • Daemonset-based installations

     Patch the daemonset using the secret you created in step 1:

     kubectl patch ds portworx --type='json' -p='[{"op": "add", "path": "/spec/template/spec/containers/0/env/0","value": {"name": "SAAS_ACCOUNT_KEY_STRING", "valueFrom":{"secretKeyRef":{"key": "account-key", "name": "px-saas-key"}}}}]' -n kube-system

3. (Air gapped only) If you’re running Portworx on an air gapped cluster, you must open the firewall to allow communication between cluster nodes and the external license server.

   NOTE: If your air gapped cluster uses an internal license server, you cannot use pay-as-you-go-licenses.

4. If you’re using traditional or extended licenses, contact support to complete the switch to pay-as-you-go billing.
