Add disclaimers regarding `Event` lifetime by dabico · Pull Request #5531 · kubernetes-sigs/headlamp

dabico · 2026-05-10T12:21:41Z

Summary

Add a small disclaimer tooltip next to the title of "Events" tables regarding Event resource lifetime in Kubernetes. Helpful to teach newbie users about Event retention, and a good reminder even for more veteran users.

Changes

Updated "Events" section in resource details to include the disclaimer.
Updated "Events" section in "Cluster" page to include the disclaimer.
Added translations.

Steps to Test

Launch locally with Minikube:

$ minikube start \
  --container-runtime=containerd \
  --docker-opt containerd=/var/run/containerd/containerd.sock \
  --kubernetes-version=v1.35.0
$ tmux new-session -d -s frontend 'make frontend-install run-frontend'
$ tmux new-session -d -s backend 'make backend run-backend'

Open Headlamp UI in the browser.
Navigate to the Clusters page and hover over the information icon to view.
Under Workloads, select any resource to view its details, hover over the information icon to view.

Screenshots

Notes for the Reviewer

Translations were only added for languages that I know and could verify the authenticity of the translation.

@copilot's comments are technically correct, but one should keep the following in mind: most managed Kubernetes services (AKS, EKS, GKE, etc.) don't offer options for configuring the kube-apiserver on the control plane (probably has something to do with them all providing more performant and robust log storage). The wording in my changes is indeed absolute, but its suggestions don't look that much better to me. At the same time, I wonder how many users run self-managed clusters, let alone change the event retention. If you have any suggestions about the wording, please let me know, and I'll change it.

yolossn · 2026-05-11T04:58:31Z

@dabico I think having a ℹ️ icon next to events Header and showing the text as tooltip on hover will be a better UX. I think its better to mention that the 1hr timelimit can vary based on Users Cluster config.

@yolossn I've implemented the suggestions. You can see what it looks like in the updated issue description. @illume I've rebased off of main. Please let me know what you both think.
