Oracle Database 19c is an industry leading relational database server.
A Helm chart is used for packaging the deployment yamls to simplify install in Kubernetes. The chart is available at helm-charts/oracle-db directory. Clone the repo and execute the following command to generate oracle-db-1.0.0.tgz
helm package helm-charts/oracle-db The Oracle Database Chart contains the Oracle Database 19c running on Oracle Linux 7. This image contains a default database in a multitenant configuration with one pdb.
For more information on Oracle Database 19c refer to Oracle Database Online Documentation.
Kubernetes 1.12+
Helm 2.x or 3.x
Using Oracle Database Docker image requires you to accept terms of service
Create image pull secrets
kubectl create secret docker-registry regcred --docker-server=container-registry.oracle.com --docker-username= --docker-password= --docker-email=
From the Oracle Container Registry website accept Terms of Service for Oracle Database Enterprise Edition.
To install the chart with the release name db19c:
Helm 3.x syntax
helm install db19c oracle-db-1.0.0.tgz Helm 2.x syntax
helm install --name db19c oracle-db-1.0.0.tgz The command deploys Oracle Database on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.
Tip: List all releases using
helm list
To uninstall/delete the db19c deployment:
Helm 3.x syntax
helm uninstall db19c Helm 2.x syntax
helm delete db19c The command removes all the Kubernetes components associated with the chart and deletes the release.
The following tables lists the configurable parameters of the Oracle Database chart and their default values.
| Parameter | Description | Default |
|---|---|---|
| oracle_sid | Database name (ORACLE_SID) | ORCLCDB |
| oracle_pdb | PDB name | ORCLPDB1 |
| oracle_pwd | SYS, SYSTEM and PDBADMIN password | Auto generated |
| oracle_characterset | The character set to use | AL32UTF8 |
| oracle_edition | The database edition | enterprise |
| persistence.size | Size of persistence storage | 100g |
| persistence.storageClass | Storage Class for PVC | |
| loadBalService | Create a load balancer service instead of NodePort | false |
| image | Image to pull | container-registry.oracle.com/database/enterprise:19.3.0.0 |
| imagePullPolicy | Image pull policy | Always |
| imagePullSecrets | container registry login/password | |
| enable_archivelog | Set true to enable archive log mode when creating the database | false |
Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
Helm 3.x syntax
helm install db19c --set oracle_sid=ORCL,oracle_pdb=prod oracle-db-1.0.0.tgz Helm 2.x syntax
helm install --name db19c --set oracle_sid=ORCL,oracle_pdb=prod oracle-db-1.0.0.tgz The above command sets the Oracle Database name to 'ORCL' and PDB name to 'prod'.
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
Helm 3.x syntax
helm install db19c -f values.yaml oracle-db-1.0.0.tgz Helm 2.x syntax
helm install --name db19c -f values.yaml oracle-db-1.0.0.tgz Tip: You can use the default values.yaml
The Oracle Database image stores the Oracle Database data files and configurations at the /opt/oracle/oradata path of the container.
Persistent Volume Claims are used to keep the data across deployments. See the Configuration section to configure the PVC or to disable persistence.
