Upgrade Usage Engine

1. Validate the Helm Chart Contents

   To ensure there are no errors in the Helm chart content, you can run the following:

   $ helm lint usage-engine-private-edition

   
   You can also run the helm template chart to see the yaml file with modified values:

   $ helm template usage-engine-private-edition

2. Upgrade all pods.

   - Use the new License Key for the upgrade. In case you have not received a new License Key, see the Release Note for the alternative method.

   - In the case the upgrade fails, it will rollback automatically. The new resources from the upgrade will be removed automatically.

   Before you upgrade, validate the helm chart with a dry-run: Note that <release_platform> is the unique names that was defined at the installation. $ helm upgrade <release_platform> usage-engine-private-edition --set-file licenseKey=<licensekey_file> --dry-run --debug --namespace <namespace> If the validation is ok, continue with the upgrade: $ helm upgrade <release_platform> usage-engine-private-edition --set-file licenseKey=<licensekey_file> --atomic --cleanup-on-fail --debug --namespace <namespace>

3. Verify the installation. STATUS Running. The READY state (ready/desired) should be 1/1, 2/2 and so on.  It can can take a few minutes before everything is in up and running.
