El Carro: The Oracle Operator for Kubernetes
Run Oracle on Kubernetes with El Carro
El Carro is a new project that offers a way to run Oracle databases in Kubernetes as a portable, open source, community driven, no vendor lock-in container orchestration system. El Carro provides a powerful declarative API for comprehensive and consistent configuration and deployment as well as for real-time operations and monitoring.
High Level Overview
El Carro helps you with the deployment and management of Oracle database software in Kubernetes. You must have appropriate licensing rights to allow you to use it with El Carro (BYOL).
With the current release, you download the El Carro installation bundle, stage the Oracle installation software, create a containerized database image (with or without a seed database), and then create an Instance (known as CDB in Oracle parlance) and add one or more Databases (known as PDBs).
After the El Carro Instance and Database(s) are created, you can take snapshot-based or RMAN-based backups and get basic monitoring and logging information. Additional database services will be added in future releases.
You can use El Carro to automatically provision and manage Oracle Database Express Edition (XE) or Oracle Database Enterprise Edition (EE). In each case, it is your responsibility to ensure that you have appropriate licenses to use any such Oracle software with El Carro.
Please also note that each El Carro “database” will create a pluggable database, which may require licensing of the Oracle Multitenant option.

We recommend starting with the quickstart first, but as you become more familiar with El Carro, consider trying more advanced features by following the user guides linked below.
If you have a valid license for Oracle 12c EE and would like to get your Oracle database up and running on Kubernetes, you can follow this quickstart guide.
To prepare the El Carro download and deployment, follow this guide.
El Carro helps you to easily create, scale, and delete Oracle databases.
Firstly, you need to create a containerized database image.
You can optionally create a default Config to set namespace-wide defaults for configuring your databases, following this guide.
Backup and Recovery
El Carro provides both storage snapshot based backup/restore and Oracle native RMAN based backup/restore features to support your database backup and recovery strategy.
After the El Carro Instance and Database(s) are created, you can create storage snapshot based backups, following this guide.
You can also create Oracle native RMAN based backups, following this guide.
To restore from a backup, follow this guide.
Data Import & Export
El Carro provides data import/export features based on Oracle Data Pump.
To import data to your El Carro database, follow this guide.
To export data from your El Carro database, follow this guide.
