  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:
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.

    Code Block
    # Verify pods

$ kubectl get pods --namespace <namespace>

#Example
NAME                                              READY   STATUS    RESTARTS   AGE

# Verify service contexts to connect

$ kubectl get services --namespace <namespace>
