The text discusses the use of Docker and Portworx to manage stateful containers, such as Couchbase, highlighting the challenges and solutions for incorporating persistence in containerized environments. It emphasizes that while containers are typically ephemeral and best suited for stateless applications, stateful containers require special treatment to ensure data persistence, replication, and high availability across different nodes and availability zones. Portworx is presented as a robust solution offering features like container granular volumes, cross availability zone high availability, and ease of deployment. The text provides a detailed guide on setting up an AWS EC2 instance, creating EBS volumes, and deploying Portworx and Couchbase containers to maintain data integrity and availability across restarts. It also touches on the debate about whether all databases should be containerized, suggesting that while not all databases need to be Dockerized, there are viable options for those that do.
