Oracle Databases for Containers and Kubernetes

Oracle offers convenient, containerized images (Podman and Docker) for a single instance, sharded, and Oracle Real Application Clusters (Oracle RAC) databases running on single or multiple hosts, reducing deployment and management work. Oracle’s database operator on Kubernetes automates the lifecycle management of Oracle Databases by extending Kubernetes APIs.

Oracle Databases for Containers and Kubernetes features

Containerized Databases on Kubernetes

Kubernetes provides orchestration for rapid provisioning of containerized Oracle Databases. Kubernetes supports faster deployments through prebuilt configurations, self-monitoring, and elasticity.

Oracle Database Operator for Kubernetes

Oracle Database offers the Kubernetes API software extensions with custom resource definitions and controllers for automating operations and lifecycle management of databases deployed within and outside Kubernetes clusters.

Benefits

Accelerate development and testing

Quickly provision databases for development and testing using prebuilt images, accelerating delivery of cloud or on-premises applications.

Consolidate databases

Reduce infrastructure costs and complexity by running more database containers on fewer servers.

Portability

Run containerized Oracle Databases across on-premises and cloud quickly and consistently.

Scalability

Add multiple containers to efficiently create more instances of Oracle Database, running only the number of containers required to support database workloads.

Automation of database management

Oracle Database Operator for Kubernetes (OraOperator) helps developers, DBAs, DevOps, and GitOps teams reduce the time and complexity of deploying and managing Oracle Databases. It eliminates the dependency on a human operator or administrator for most database operations.

Kubernetes APIs extended for database lifecycle management and deployment

Oracle Database is natively part of the Kubernetes infrastructure to start, stop, monitor, patch, upgrade, and perform other lifecycle management operations from Kubernetes. It provides these capabilities whether your Oracle Database is in the cloud, on-premises, or in Kubernetes.
