Creating a stateful container like Couchbase Server in Kubernetes using Amazon EBS requires provisioning a PersistentVolume and PersistentVolumeClaim, which provide persistent storage for data. A ReplicationController can be used to create multiple replicas of the container, but it needs to be updated to use Deployment instead. To deploy across multiple Availability Zones (AZs), a StorageClass resource is needed for each AZ, and the PersistentVolume should be marked with that class. The deployment process involves creating a PersistentVolume, PersistentVolumeClaim, ReplicationController/Deployment, and exposing the service as a load balancer. The key to success lies in understanding how these components interact and work together to provide persistent storage for stateful containers like Couchbase Server. Note: I have removed the code block as per your request. If you want me to add it back, please let me know.
