License issues

License issues can happen even after you have applied the license via a Helm values file. Use the following processes to identify and troubleshoot license issues.

Check for a NextGen license

Use the following steps to confirm that your Harness installation includes a NextGen license:

1. Use the kubectl get secret command to retrieve your MongoDB password:

   kubectl get secret -n <namespace> mongodb-replicaset-chart -o jsonpath={.data.mongodb-root-password} | base64 --decode | awk '{print $1}'

2. Use kubectl exec to open an interactive shell session in the MongoDB container:

   kubectl exec -it mongodb-replicaset-chart-0 -n <namespace> -- /bin/sh

3. Connect to the MongoDB instance:

   mongo

4. Use the following commands to authenticate to the database in the admin role:

   use admin
   db.auth(`admin`, <password>)

5. Set the context to Harness NextGen and run the find operation to locate the license for Harness NextGen:

   use ng-harness
   db.moduleLicenses.find({})

6. If the licenses are present in the database, then proceed with Refresh a NextGen license.

Refresh a NextGen license

Use the following strategies to refresh a NextGen license.

Discard the redis cache for the NextGen license

Use the following commands to discard the redis cache for the NG license.

1. Retrieve the redis master host:

   kubectl exec -it redis-sentinel-harness-server-0 -n <namespace> -- redis-cli info | grep master_host | cut -c 13-

2. Find the redis master service:

   kubectl get svc -n <namespace> | grep <IP-From-Previous-Command>

   Copy the service name.

3. Delete the license keys:

   kubectl exec -it <Service-From-Previous-Step> -n <namespace> -- redis-cli del "hCache/NGLicense" "jcache_timeout_set:{hCache/NGLicense}"

4. Reload the UI.

If this does not refresh the license:

• Repeat the process a second time.
• Wait 5 minutes before you reload the UI.

If the license does not refresh, use the following process to temporarily disable caching in ng-manager.

Disable NG cache

If discarding the redis cache does not refresh the NextGen license, use the following process to temporarily disable caching in ng-manager.

1. Use the kubectl edit configmap command to open the ng-manager ConfigMap for editing. Replace the <namespace> placeholder with your Harness installation namespace.

   kubectl edit configmap ng-manager -n <namespace>

2. Change the value of CACHE_BACKEND to NOOP.

3. Restart your ng-manager pods:

   kubectl rollout restart deploy ng-manager -n <namespace>
