Upgrade

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

   
   [hide] Line Brake [/hide]

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:
   
   $ 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.

   # Verify pods
   
   $ kubectl get pods --namespace <namespace>

   Note!

   The output will show the exposed ports when you run kubectl get services. We have used a default namespace and helm chart for efs-provisioner,  external-dns and aws-alb-ingress-controller from 3PP → "Readme" instruction from zip file in /wiki/spaces/DRXXE/pages/6194875
