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 mzuepe-operator-controller-manager-0 2/2 Running 0 154m mzonlinedesktop-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 mzuepe-operator-controller-manager-metrics-service ClusterIP 10.107.192.50 <none> 8443/TCP 154m mzuepe-operator-controller-manager-service ClusterIP 10.100.197.208 <none> 443/TCP 154m mzonline 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
   title 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.

Manual ECD rolling update

In the case Automatic Rolling Update was never defined for the ECDs, you need to enter the Web interface and manually upgrade the ECDs to the new image by clicking Upgrade in the EC deployment interface.
