SPK Licensing¶

Overview¶

The Service Proxy for Kubernetes (SPK) software requires a valid SPK license to begin processing 5G application traffic using SPK CRs. Once the SPK CWC obtains a valid license, it begins collecting and reporting monthly SPK software telemetry statistics for the cluster. SPK uses F5’s flexible consumption software licensing model, billing only for the SPK features used.

_images/spk_info.png Note: SPK Licensing applies to the cluster level, and is performed prior to installing the SPK Controller instances.

This document guides you through the activating the SPK software license.

Licensing stages¶

The CWC’s Common Product Component and Libraries (CPCL) module operates in disconnected mode; having no direct access to the internet. Uploading the license reports, and obtaining signed license acknowledgements from the F5 licensing server must occur at some point between the cluster and the internet. In this document, the Postman platform is used for licensing. Once the CWC and Controllers are installed, the licensing and entitlement events occur as follows:

Obtain the JSON Web Token (JWT).
Check CWC licensing status.
Download the CWC cluster report.
Send the report to the F5 licensing server.
Send the signed acknowledgement to CWC.

Telemetry reports¶

Once the cluster is successfully licensed, the CWC enters a Telemetry In Progress state, calculating the software usage statistics for the cluster. At the end of each month, the CWC generates a telemetry report which should be downloaded, sent to the F5 licensing server for acknowledgement, and the signed acknowledgement should then be sent back to the CWC. If a telemetry report is not signed by the F5 licensing server at the end of the month, it will be consolidated with the next telemtry report, and a consolidated report will then be available to download and sign.

Example of the Telemetry In Progress and report EndDate:

"TelemetryStatus": {
    "NextReport": {
        "StartDate": "2022-04-26 17:59:35.306014074",
        "EndDate": "2022-04-30 17:59:35",
        "State": "Telemetry In Progress"
    }
}

License expiration¶

The cluster license requires renewal after the LicenseExpiryDate has passed. It is important to note that SPK does not stop processing application traffic after this time, but will begin logging messages indicating the cluster must be relicensed.

Example of the LicenseExpiryDate:

"LicenseDetails": {
    "DigitalAssetID": "5ec9234e-8df3-4d90-9536-45142b87049f",
    "EntitlementType": "paid",
    "LicenseExpiryDate": "2022-11-17T00:00:00Z",
    "LicenseExpiryInDays": "204"
}

Licensing APIs¶

The CWC licensing APIs listed below can be used to perform licensing tasks programmatically, or with API platforms other than Postman. Refer to the Gather API info section to obtain the CWC’s SSL/TLS certificate and IP address info. To use the Postman API platform, refer to the Procedures section of this document.

_images/spk_warn.png Important: The URL to contact the CWC Pod includes the Project name. In the examples below the CWC is in the spk-telemetry Project.

License status¶

Returns the current CWC licensing status. This API should be used both for licensing the cluster and checking the telemetry report status. The LicenseStatus should indicate Config Report Ready to Download prior to downloading a license report.

https://f5-spk-cwc.spk-telemetry:30881/status

License report¶

Downloads the CWC license report for the cluster. The license report will be sent to the F5 licensing server for acknowledgement.

https://f5-spk-cwc.spk-telemetry:30881/report

Send report¶

Sends the license report to Telemetry server for acknowledgement. Send the full report, including the {} curly brackets.

Note: The DigitalAssetID is obtained from the License status, and the JWT from your MyF5 account.

https://product.apis.f5.com/ee/v1/entitlements/telemetry \
-H "Content-Type: application/json" -H "F5-DigitalAssetId: <DigitalAssetID>" \
-H "User-Agent: SPK" -H "Authorization: Bearer <JWT Object>" -d {"report":"eyJhbG7ImRvYZW50"}

Send manifest¶

Sends the acknowledged manifest to CWC. Send only the manifest data, no curly brackets {}, or “ quotations.

https://f5-spk-cwc.spk-telemetry:30881/receipt -d eyJhbGciOiJSUzUxMiIs

Requirements¶

Ensure you have:

A workstation with Postman installed, and internet access.
Installed the SPK software.
Installed the SPK CWC.
Obtained the JWT for this cluster from your MyF5 account.

Procedures¶

Gather API info¶

Licensing the SPK software requires querying the CWC REST API to determine the cluster’s licensing status, and uploading a valid license. To authenticate the CWC REST API, the SSL/TLS certificates and the IP address of the API interface must first be obtained. Use the steps below to obtain the API information.

Create a new directory for the CWC REST API certificates:
```
mkdir cwc_api
```

Copy each of the certificates into the new directory:

cp api-server-secrets/ssl/client/certs/client_certificate.pem cwc_api

cp api-server-secrets/ssl/ca/certs/ca_certificate.pem cwc_api

cp api-server-secrets/ssl/client/secrets/client_key.pem cwc_api

Obtain the name of the CWC Pod in the cluster:

In this example, the CWC is in the spk-telemetry Project.
```
oc get pods -n spk-telemetry | grep f5-spk-cwc
```
In this example, the CWC Pod is named f5-spk-cwc-86d89c4548-fmwpl.
```
f5-spk-cwc-86d89c4548-fmwpl   2/2     Running
```
Obtain the IP address of the node the CWC Pod is scheduled on:

In this example, the CWC is in the spk-telemetry Project.
```
oc describe pod f5-spk-cwc-86d89c4548-fmwpl -n spk-telemetry | grep Node:
```
In this example, the CWC Pod is running on worker-0.ocp.f5.com with IP address 10.144.175.18.
```
Node:         worker-0.ocp.f5.com/10.144.175.18
```
Edit the hosts file on your system, or setup DNS resolution mapping the node IP address to the CWC’s hostname:

Important: The CWC hostname is required for SSL/TLS certiicate validation.
```
10.172.241.230 f5-spk-cwc.<project>
```
In this example, the CWC is in the spk-telemetry Project.
```
10.172.241.230 f5-spk-cwc.spk-telemetry
```
