StatefulSets

StatefulSets manages the deployment and scaling of stateful applications, ensuring each pod has a unique, persistent identity and storage. They are ideal for applications requiring stable network identities, ordered deployment, and persistent data storage, such as databases or distributed systems.

Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of these Pods.

Like a Deployment, a StatefulSet manages Pods that are based on an identical container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity for each of its Pods. These pods are created from the same spec, but are not interchangeable: each has a persistent identifier that it maintains across any rescheduling.

Once a user click on the Statefulsets Tab it will show the list of statefulsets.

From  here user can click on any statefulsets from the list and view all the details status and configuration.

User will be able to edit the Manifest as needed and apply new manifest

Use Case of StatefulSets -

• Persistent Storage
• Stable Network Identity
• Ordered Deployment and Scaling
• Database Clustering
