@aantn could you please have a look? :)

@pavangudiwada do you might have time to review? :)

[pavangudiwada]

We are sorry for the delay @lippertmarkus, our team is looking into this now

Update: @lippertmarkus I'm working on this PR now, making some final checks for compatibility.

[lippertmarkus]

Would be great if we could add an automated process to keep the kube-prometheus-stack dependency up to date

Hi @lippertmarkus, extremely sorry, this took way too long than expected. Thank you for your patience. We had to perform many checks to make sure the new version is compatible with the Robusta UI too. We hope this process will be faster next time.

For future reference, here are all the checks we performed:

1. Install Robusta with updated Kube Prometheus Stack on new GKE and EKS clusters and check for issues. Trigger demo alerts and see if they are working correctly.
   • Ensure there are no errors in pod logs for Prometheus Operator, Alertmanager, Prometheus, and Robusta Runner.
   • Make sure to check oomkilled pods, which should have graphs with data included.
   • Check at least one Prometheus alert (not an APIServer finding):
     • Before enabling managed Prometheus alerts in Robusta (the alert comes straight from KPS).
     • After enabling managed Prometheus alerts (the alert comes from our SaaS).
2. Upgrade path: Deploy the current version of Robusta without this fix and then deploy with the new KPS version. Look for any errors or issues.
3. Ensure the functionality in the UI related to these specific pages still works after the updates.
   • AI features.
   • Logs & Graphs on every page in Robusta, including:
     • Apps.
     • App details (a specific app).
     • Nodes.
     • Node details (a specific node).
     • Job details (for a job that ran more than 5 min).
4. Silences - Can create and view silences.
5. Efficiency page - Can run a new scan, view the results, and see recommendations (not a ‘?’ sign).
6. Check the change log for any new changes that we should be aware of.
