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:

   Code Block
   $ helm lint usage-engine-private-edition

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

   Code Block
   $ 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.
   

   Code Block

   Before you upgrade, validate the helm chart with a dry-run: $ helm upgrade <release_name_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_name_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.

   Code Block
