Deploying Db2 using a custom resource

Once the Db2 Operator is installed, use a custom resource (CR) to deploy Db2.

Db2uCluster is our initial custom resource offering. All the multiple logical node (MLN) share the same data volume within each pod.

The Db2uCluster CR provides comparatively better performance on software-defined storage types, such as OpenShift Data Foundation (ODF) and Portworx. The Db2uInstance CR provides a significant performance increase on cloud platforms such as Amazon Web Services (AWS) and Azure.

Whether you are deploying to on-premise with software-defined storage types or to on-cloud platforms with cloud-native storage, you can choose to use either custom resource.
