Manage clusters

ob-operator defines the following custom resource definitions (CRDs) based on the deployment mode of OceanBase clusters:

• obclusters.oceanbase.oceanbase.com defines OceanBase clusters. You can define OceanBase clusters and perform cluster O&M tasks by modifying this resource definition.
• obzones.oceanbase.oceanbase.com defines a specific zone and is used for O&M of the zone. Generally, you do not need to modify this resource definition. ob-operator automatically maintains this resource definition.
• observers.oceanbase.oceanbase.com defines a specific OBServer node and is used for O&M of the OBServer node. Generally, you do not need to modify this resource definition. ob-operator automatically maintains this resource definition.
• obparameters.oceanbase.oceanbase.com defines parameters of OceanBase Database and is used for O&M of parameters. Generally, you do not need to modify this resource definition. ob-operator automatically maintains this resource definition.

You can implement the O&M of OceanBase clusters by creating or modifying obparameters.oceanbase.oceanbase.com. For example, you can perform the following O&M tasks:

• Create a cluster
• Add zones to a cluster
• Delete zones from a cluster
• Add OBServer nodes to zones
• Delete OBServer nodes from zones
• Upgrade a cluster
• Manage parameters
• Delete a cluster
