v0.9.0

[etcd-druid]

⚠️ Breaking Changes

• [OPERATOR] If Spec.Replicas in ETCD CR is greater than 0 and a even number, then no statefulset for ETCD nodes will be created and so the ETCD cluster won't be setup by Druid (gardener/etcd-druid#314, @abdasgupta)

✨ New Features

• [USER] Add SchedulingConstraints field to Etcd spec. The currently supported constraints are Affinity and TopologySpreadConstraints. (gardener/etcd-druid#329, @shreyas-s-rao)

🐛 Bug Fixes

• [OPERATOR] A bug has been fixed which prevented the ServiceAccount's automountServiceAccountToken field from being reconciled. (gardener/etcd-druid#316, @rfranzke)

🏃 Others

• [OPERATOR] Deployed configmap programmatically as component instead of chart (gardener/etcd-druid#314, @abdasgupta)
  • configmap configures ETCD config based on the number of nodes in cluster. Number of nodes in cluster is derived from spec.Replicas of ETCD CR
  • Introduced separate TLS config for client and peer communication with ETCD cluster

[etcd-backup-restore]

📰 Noteworthy

• [OPERATOR] Multi-node etcd bootstrapping is now supported. This is an alpha feature intended for initial use and evaluation. Please do not enable this feature for your productive workloads (gardener/etcd-backup-restore#419, @abdasgupta)
  • Multi-node etcd restoration from backup buckets is not supported
  • Intended to work only with etcd-druid v0.9.x and beyond
  • Intended to work only with etcd-custom-image v3.4.13-bootstrap-4 and beyond
