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

If you have already set up your cluster using any of the paid, trial, or free Portworx licenses, you can switch to pay-as-you-go billing by acquiring a pay-as-you-go account key from the Pure Storage support team and performing the following steps.

Prerequisites

• A pay-as-you-go account key, acquired by contacting the Pure Storage support team.

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 portworx

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

   • Operator-based installations:

     1. Patch the StorageCluster stc with the following command:

        stc=$(kubectl get stc -n portworx -o jsonpath='{.items[0].metadata.name}')

     2. 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 portworx

        The above step patches your StorageCluster stc and appends the following under the env: parameter. This will enable pay-as-you-go billing on your cluster.

        .

        env:
        - name: "SAAS_ACCOUNT_KEY_STRING"
          valueFrom:
            secretKeyRef:
              name: px-saas-key
              key: account-key

     3. Wait for a few minutes and then verify if the automatic rolling upgrade is successful by running the following command. You will observe that the new pods have been created recently with new px-cluster-<id>. You can also see the latest timestamp under AGE, as shown in the following example:

        kubectl get pods -n portworx -l name=portworx

        NAME                                                    READY   STATUS    RESTARTS   AGE
        px-cluster-60403120-fdec-470b-af4e-ef93c42d8aeb-b66td   2/2     Running   0          6m56s
        px-cluster-60403120-fdec-470b-af4e-ef93c42d8aeb-fqdgj   2/2     Running   0          5m16s
        px-cluster-60403120-fdec-470b-af4e-ef93c42d8aeb-t8ldc   2/2     Running   0          9m

     4. Check your SaaS key license usage by running pxctl status from one of the worker nodes:

        pxctl status

        Status: PX is operational
        Telemetry: Disabled or Unhealthy
        Metering: Healthy
        License: PX-Enterprise Usage Based (expires in 209 days)
        ...
                

        To see more detailed information about your license run pxctl license list

        pxctl license list

   • 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 portworx

How to apply a new pay-as-you-go key secret

If you need to update your pay-as-you-go key secret, you can export the secret object to a YAML file, apply the secret, and then perform a rolling update by adding a dummy env variable to your StorageCluster stc:

1. Export the YAML file:

   kubectl get secret/px-saas-key -n portworx -o yaml > px-saas-key.yaml

2. After editing the file with your new pay-as-you-go key secret, run the kubectl apply command:

    kubectl apply -f px-saas-key.yaml

3. Get your px-cluster ID using pxctl status, and run the following command to trigger the Portworx pod rolling update:

   kubectl patch stc <px-cluster-ID> -n portworx --type "json" -p '[{"op":"add","path":"/spec/env/-","value":{"name":"DUMMYENV","value":"date"}}]'
