Container Orchestration for Oracle DBAs
summary
Kubernetes is framed as essential context for DBAs but the database stays outside the cluster: the demo deploys a JavaScript front end and Oracle REST Data Services into k8s while Oracle XE on VM remains external, and the front end successfully queries the employees table over HTTP JSON. Tools shown include Docker, kubectl, Deployments/ReplicaSets, StatefulSets, ConfigMaps and Secrets, NodePort and LoadBalancer services, persistent volumes and GitLab CI integration. Practical claims: you can run ORDS in k8s, do rolling upgrades and canary deploys, and keep the DB as a managed external service.
