# etcd-defrag chart This chart installs a [CronJob](https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/) that will periodically defragment the etcd keyspace for a cluster that is managed using [kubeadm](https://kubernetes.io/docs/reference/setup-tools/kubeadm/). It is installed as part of the [cluster-addons](../cluster-addons).
