@thpang , I think we intentionally removed the metrics-server APP_VERSION from our yaml a while ago since it had no bearing on the chart install and seemed confusing, however, wondering if our doc should say something about which app version of metrics-server is installed by default since that is not easy to tell on the surface?

Might be a good idea to reference like you said

We did remove that appVersion in viya4-deployment where metrics server is installed specifically for AWS, however we never had the appVersion in this repo.
However, I do agree that having an quick reference for users to figure out what appVersion the chart version translates to would be useful. In this repo the METRICS_SERVER_* variables are not documented but a user could change them if they come across it, in viya4-deployment it is exposed and present in the config-vars. I have another ticket to also make an update in that repo and will include a link for the user in the doc to determine the metrics server appVersion.

@jarpat , that sounds like it would be a helpful addition in both projects. Thanks for adding it.
