Comparing deployment and StatefulSets
Deployments are designed to manage any sets of pods. They can also be used to manage the pods of a distributed data store. StatefulSets were specifically designed to support the needs of distributed data stores. However, the special properties of ordering and uniqueness are not always necessary. Let's compare deployments to StatefulSets and see for ourselves:
- Deployments don't have associated storage, whereas StatefulSets do.
- Deployments have no associated service, whereas StatefulSets do.
- Deployment pods have no DNS name, whereas StatefulSet pods do.
- Deployments launch and terminate pods in any order, whereas StatefulSets follow a prescribed order (by default).
I recommend that you stick to deployments ...
