Modifying the CR to customize your IBM Match 360 installation

A custom resource (CR) enables you to configure how the IBM Match 360 service is installed in your environment. You can tune and customize the installation by modifying the properties of the CR.

This topic documents a subset of the configuration options that you can include in the spec section of the IBM Match 360 CR (mdm-cr). If you do not specify a value for a property, the default value is used.

IBM Match 360 provides t-shirt sizing to enable you to scale the service installation up or down. For information about scaling IBM Match 360 and other services, see Scaling services.

For each IBM Match 360 microservice, you can change CR options related to resource allocation. When you specify custom values for resource allocation options, those values are applied after any service-level scaling configuration that is in place (such as small, medium, or large). The custom values specified here override the scaling default values.

Important: Changing the default resource configuration has an impact on the performance of the service. Only modify the configuration options if you are certain of your changes. Be prepared to revert your changes if necessary.
Custom resource details
Kind: mdm
Default CR name: mdm-cr

Modifying the CR after installation

You can edit the IBM Match 360 CR after installing the service.

To edit the value of a single property in the IBM Match 360 CR (mdm-cr) spec, use the oc patch command.
oc patch mdm mdm-cr --namespace ${PROJECT_CPD_INST_OPERANDS} -p '{"spec":{"parameterName":"parameterValue"}}' --type=merge
To edit the values of multiple properties in the IBM Match 360 CR (mdm-cr) spec, use the oc edit command. 
oc edit mdm mdm-cr --namespace ${PROJECT_CPD_INST_OPERANDS}
