Oracle Database Operator for Kubernetes

Make Oracle Database Kubernetes Native

As part of Oracle's resolution to make Oracle Database Kubernetes native (that is, observable and operable by Kubernetes), Oracle released Oracle Database Operator for Kubernetes (OraOperator or the operator). OraOperator extends the Kubernetes API with custom resources and controllers for automating Oracle Database lifecycle management.

In this v1.0.0 production release, OraOperator supports the following database configurations and infrastructure:

Oracle Autonomous Database:
- Oracle Autonomous Database shared Oracle Cloud Infrastructure (OCI) (ADB-S)
- Oracle Autonomous Database on dedicated Cloud infrastructure (ADB-D)
- Oracle Autonomous Container Database (ACD) (infrastructure) the infrastructure for provisionning Autonomous Databases.
Containerized Single Instance databases (SIDB) deployed in the Oracle Kubernetes Engine (OKE) and any k8s where OraOperator is deployed
Containerized Sharded databases (SHARDED) deployed in OKE and any k8s where OraOperator is deployed
Oracle Multitenant Databases (CDB/PDBs)
Oracle Base Database Cloud Service (BDBCS)
Oracle Data Guard (Preview status)

Oracle will continue to extend OraOperator to support additional Oracle Database configurations.

Features Summary

This release of Oracle Database Operator for Kubernetes (the operator) supports the following lifecycle operations:

ADB-S/ADB-D: Provision, Bind, Start, Stop, terminate (soft/hard), scale (up/down), Manual Backup, Manual Restore
ACD: provision, bind, restart, terminate (soft/hard)
SIDB: Provision, clone, patch (in-place/out-of-place), update database initialization parameters, update database configuration (Flashback, archiving), Oracle Enterprise Manager (EM) Express (a basic observability console), Oracle REST Data Service (ORDS) to support REST based SQL, PDB management, SQL Developer Web, and Application Express (Apex)
SHARDED: Provision/deploy sharded databases and the shard topology, Add a new shard, Delete an existing shard
Oracle Multitenant Database: Bind to a CDB, Create a PDB, Plug a PDB, Unplug a PDB, Delete a PDB, Clone a PDB, Open/Close a PDB
Oracle Base Database Cloud Service (BDBCS): provision, bind, scale shape Up/Down, Scale Storage Up, Terminate and Update License
Oracle Data Guard: Provision a Standby for the SIDB resource, Create a Data Guard Configuration, Perform a Switchover, Patch Primary and Standby databases in Data Guard Configuration

The upcoming releases will support new configurations, operations and capabilities.

Release Status

This production release has been installed and tested on the following Kubernetes platforms:

Oracle Container Engine for Kubernetes (OKE) with Kubernetes 1.24
Oracle Linux Cloud Native Environment(OLCNE) 1.6
Minikube with version v1.29.0
Azure Kubernetes Service
Amazon Elastic Kubernetes Service
Red Hat OKD
Red Hat OpenShift

Prerequisites

Oracle strongly recommends that you ensure your system meets the following Prerequisites.

Install cert-manager

The operator uses webhooks for validating user input before persisting it in etcd. Webhooks require TLS certificates that are generated and managed by a certificate manager.

Install the certificate manager with the following command:
```
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.12.0/cert-manager.yaml
```

Quick Install of the Operator

To install the operator in the cluster quickly, you can use a single oracle-database-operator.yaml file.

Run the following command

kubectl apply -f https://raw.githubusercontent.com/oracle/oracle-database-operator/main/oracle-database-operator.yaml

Ensure that the operator pods are up and running. For high availability, Operator pod replicas are set to a default of 3. You can scale this setting up or down.

$ kubectl get pods -n oracle-database-operator-system

  NAME                                                                 READY   STATUS    RESTARTS   AGE
  pod/oracle-database-operator-controller-manager-78666fdddb-s4xcm     1/1     Running   0          11d
  pod/oracle-database-operator-controller-manager-78666fdddb-5k6n4     1/1     Running   0          11d
  pod/oracle-database-operator-controller-manager-78666fdddb-t6bzb     1/1     Running   0          11d

Check the resources

You should see that the operator is up and running, along with the shipped controllers.

For more details, see Oracle Database Operator Installation Instructions.

Getting Started

The quickstarts are designed for specific database configurations:

YAML file templates are available under /config/samples. You can copy and edit these template files to configure them for your use cases.

Uninstall the Operator

To uninstall the operator, the final step consists of deciding whether you want to delete the custom resource definitions (CRDs) and Kubernetes APIServices introduced into the cluster by the operator. Choose one of the following options:

Deleting the CRDs and APIServices

To delete all the CRD instances deployed to cluster by the operator, run the following commands, where is the namespace of the cluster object:

kubectl delete oraclerestdataservice.database.oracle.com --all -n <namespace>
kubectl delete singleinstancedatabase.database.oracle.com --all -n <namespace>
kubectl delete shardingdatabase.database.oracle.com --all -n <namespace>
kubectl delete dbcssystem.database.oracle.com --all -n <namespace>
kubectl delete autonomousdatabase.database.oracle.com --all -n <namespace>
kubectl delete autonomousdatabasebackup.database.oracle.com --all -n <namespace>
kubectl delete autonomousdatabaserestore.database.oracle.com --all -n <namespace>
kubectl delete autonomouscontainerdatabase.database.oracle.com --all -n <namespace>
kubectl delete cdb.database.oracle.com --all -n <namespace>
kubectl delete pdb.database.oracle.com --all -n <namespace>
kubectl delete dataguardbrokers.database.oracle.com --all -n <namespace>

After all CRD instances are deleted, it is safe to remove the CRDs, APIServices and operator deployment. To remove these files, use the following command:

kubectl delete -f oracle-database-operator.yaml --ignore-not-found=true

Note: If the CRD instances are not deleted, and the operator is deleted by using the preceding command, then operator deployment and instance objects (pods, services, PVCs, and so on) are deleted. However, if that happens, then the CRD deletion stops responding. This is because the CRD instances have properties that prevent their deletion, and that can only be removed by the operator pod, which is deleted when the APIServices are deleted.

You can submit a GitHub issue, and/or you file an Oracle Support service request, using this product ID: 14430.

Security

Secure platforms are an important basis for general system security. Ensure that your deployment is in compliance with common security practices.

Managing Sensitive Data

Kubernetes secrets are the usual means for storing credentials or passwords input for access. The operator reads the Secrets programmatically, which limits exposure of sensitive data. However, to protect your sensitive data, Oracle strongly recommends that you set and get sensitive data from Oracle Cloud Infrastructure Vault, or from third-party Vaults.

The following is an example of a YAML file fragment for specifying Oracle Cloud Infrastructure Vault as the repository for the admin password.

 adminPassword:
      ociSecretOCID: ocid1.vaultsecret.oc1...

Examples in this repository where passwords are entered on the command line are for demonstration purposes only.
