Option 1: Preparing your cluster for an online deployment

Make sure that you prepare your environment and install the necessary software before you go to the resources to install the IBM certified software.

Before you begin

The following progress bar shows you where you are in the installation process. You can click the completed parts in the diagram to go back and check that you did everything that you needed to do.

About this task

The administrator must make sure that the target cluster meets all of the requirements. Make sure that the client that you connect with has all the necessary tools.

The following diagram shows the steps that are involved in installing a production deployment on OCP or ROKS.

Tip: Whenever possible, work with subject matter experts to help you prepare each pattern that you intend to install. Patterns can be installed with a minimum amount of customization with default secrets and configurations. However, you are more than likely to want to customize a pattern at some point. Therefore, you must assess the configuration parameters with the help of the software experts to identify the values that you need to provide to the custom resource.

The resources that you need to create does depend on whether you want to install the operator in "all namespaces on your cluster". The scripts create the needed image pull secrets and persistent volume claims for you in the target namespace and the openshift-operators namespace. If you use the OpenShift console, you need to create all of these resources in both namespaces.

Important: If you plan to use Db2®, make sure that Db2 does not run any compatibility features before you create the databases. Run the following Db2 commands before you create the databases to set the compatibility features to NULL (default).

db2set DB2_COMPATIBILITY_VECTOR= 
db2stop
