Frequently Asked Questions
Common questions about etcd releases and lifecycle.
How long are etcd versions supported?
etcd supports the latest two minor release branches. Older versions stop receiving patches. Since etcd backs Kubernetes, keeping it updated is critical.
Why is etcd important for Kubernetes?
etcd is the backing store for all Kubernetes cluster data including configuration, state, and metadata. A healthy etcd cluster is essential for a healthy Kubernetes cluster.
How often does etcd release updates?
etcd ships minor versions roughly every 6-12 months. Patch releases with bug fixes and security patches ship as needed.
Can I use etcd outside of Kubernetes?
Yes, etcd is a general-purpose distributed key-value store. It is used for service discovery, configuration management, and distributed locking outside of Kubernetes.
