Changes and Releases

Updates on Giant Swarm workload cluster releases, apps, UI improvements and documentation changes.

• May 26, 2026 Observability tempo-app v0.17.0

  Changed

  • Upgrade Tempo Vulture chart from 0.12.9 to 0.12.10 (only bumps the tempo-vulture image from 2.10.4 to 2.10.5)
  • Upgrade Tempo chart from 2.14.3 to 2.23.0
    • Upgrades Tempo from 2.10.4 to 2.10.5
    • Bumps the rollout-operator sub-dependency from 0.47.0 to 0.49.0
    • Adds (disabled by default) experimental backend-scheduler / backend-worker components (chart 2.17.0)
    • Several components migrated to a shared pod template / defaults layer (chart 2.16.x – 2.17.x)
    • Adds unhealthyPodEvictionPolicy support on every PodDisruptionBudget (chart 2.23.0)
  • [BREAKING] Tempo chart 2.17.10 converts the memcached Service to headless (clusterIP: None) and changes the StatefulSet serviceName. Both fields are immutable, so helm upgrade will fail on existing installations with: Service "tempo-memcached" is invalid: spec.clusterIPs[0]: Invalid value: ["None"]: may not change once set && StatefulSet.apps "tempo-memcached" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', ... Before upgrading, delete the affected Services and orphan-delete the StatefulSets so the new chart can recreate them:

    kubectl -n <namespace> delete service --selector 'app.kubernetes.io/instance=<release>,app.kubernetes.io/component in (memcached,memcached-bloom,memcached-parquet-footer,memcached-frontend-search)'
    kubectl -n <namespace> delete statefulset --selector 'app.kubernetes.io/instance=<release>,app.kubernetes.io/component in (memcached,memcached-bloom,memcached-parquet-footer,memcached-frontend-search)' --cascade=orphan
