It enables management of etcd clusters through [declarative Kubernetes API model](api/core/v1alpha1/crds/druid.gardener.cloud_etcds.yaml). \n\nIn every etcd cluster managed by `etcd-druid`, each etcd member is a two container `Pod` which consists of:\n\n- [etcd-wrapper](https://github.com/gardener/etcd-wrapper) which manages the lifecycle (validation \u0026 initialization) of an etcd.\n- [etcd-backup-restore](https://github.com/gardener/etcd-backup-restore) sidecar which currently provides the following capabilities (the list is not comprehensive):\n  - [etcd](https://github.com/etcd-io/etcd) DB validation.\n  - Scheduled [etcd](https://github.com/etcd-io/etcd) DB defragmentation.\n  - Backup - [etcd](https://github.com/etcd-io/etcd) DB snapshots are taken regularly and backed in an object store if one is configured.\n  - Restoration - In case of a DB corruption for a single-member cluster it helps in restoring from latest set of snapshots (full \u0026 delta).\n  - Member control operations.\n\n`etcd-druid` additionally provides the following capabilities:\n\n- Facilitates declarative scale-out of [etcd](https://github.com/etcd-io/etcd) clusters.\n- Provides protection against accidental deletion/mutation of resources provisioned as part of an etcd cluster.\n- Offers an asynchronous and threshold based capability to process backed up snapshots to:\n  - Potentially minimize the recovery time by leveraging restoration from backups followed by [etcd's compaction and defragmentation](https://etcd.io/docs/v3.4/op-guide/maintenance/). \n  - Indirectly assert integrity of the backed up snaphots.\n- Allows seamless copy of backups between any two object store buckets.\n\n## Start using or developing `etcd-druid` locally\n\nIf you are looking to try out druid then you can use a [Kind](https://kind.sigs.k8s.io/) cluster based setup.  \n\nhttps://github.com/user-attachments/assets/cfe0d891-f709-4d7f-b975-4300c6de67e4\n\nFor detailed documentation, see our [docs](https://gardener.github.io/etcd-druid/index.html).\n\n## Contributions\n\nIf you wish to contribute then please see our [contributor guidelines](docs/development/contribution.md).\n\n## Feedback and Support\n\nWe always look forward to active community engagement.
