Prometheus Addon Is Not Getting Upgraded During The K8s Upgrade.

Problem

During the K8s upgrade/patch upgrade the Prometheus Addon Is Not Getting Upgraded. All the other addons are getting new higher versions.

Environment

• Platform9 Managed Kubernetes - v5.4.0 and Higher.

Cause

The users could have customized monitoring addon, so selective upgrading of different components is also not possible.

For example, if we only upgrade Grafana deployment, we might end up removing customizations like additional dashboards if they have been configured.

Resolution

The simplest way to upgrade, would be to delete and reinstall the addon from the Platform9 Management UI >> Clusters >> Choose the cluster >> Addons >> Disable Prometheus Monitoring addons >> Wait for atleast 90 seconds to complete the removal process in the backend >> Enable Prometheus Monitoring Addon.
