Oracle Databases for Containers and Kubernetes
Oracle offers convenient, containerized images (Podman) 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
Containerized images can be consumed with minimal effort and deployed in the cloud and on-premises environments.
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.
Portability
Run containerized Oracle Databases across on-premises and cloud quickly and consistently.
Consolidate databases
Reduce infrastructure costs and complexity by running more database containers on fewer servers.
Scalability
Add multiple containers to efficiently create more instances of Oracle Database, running only the number of containers required to support database workloads.
Benefits
Orchestration of infrastructure for database deployment
Leverage Oracle Database containerized images to automate deployment and integration with your IT infrastructure.
Monitoring of infrastructure resources
Monitor resources to maintain the high availability of application states and scale or descale database pods based on your workload requirements.
Benefits
OraOperator Release v 2.1.0
What’s New in v2.1.0
OraOperator v2.1.0 enhances Kubernetes native Oracle Database operations with improved RAC provisioning, scaling, ASM integration, and maintenance. It strengthens Pluggable Database (PDB) lifecycle management via wallet-based secrets, better tracing, and online password resets. Oracle REST Data Services (ORDS) gains improved credential/config handling. The release adds resilience fixes and broad support across major Kubernetes platforms and Oracle Database configurations.
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.
