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.

    # Verify pods

$ kubectl get pods --namespace <namespace>

#Example
NAME                                              READY   STATUS    RESTARTS   AGE

uepe-operator-controller-manager-646b766d44-mmzhs 2/2     Running   0          154m
desktop-online-7ff989968b-9hd2b                   1/1     Running   0          154m
platform-0                                        1/1     Running   0          154m

# Verify service contexts to connect

$ kubectl get services --namespace <namespace>

#Example
NAME                                             TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                         AGE
uepe-operator-controller-manager-metrics-service ClusterIP   10.107.192.50    <none>        8443/TCP                        154m
uepe-operator-controller-manager-service         ClusterIP   10.100.197.208   <none>        443/TCP                         154m
desktop-online                                   NodePort    10.101.65.181    <none>        80:31200/TCP,443:31300/TCP      154m
platform                                         NodePort    10.96.40.10      <none>        9000:31600/TCP,6790:31700/TCP   154m

    Note!

    The output will show the exposed ports when you run kubectl get services -n <namespace>. The exposed ports must be used instead of the ports 443, 9000, 6790, 80 and 9999

    when you connect to the Desktop and/or MzOnline.
