Setting up the cluster for OpenPages
If you plan to install OpenPages® on IBM® Cloud Pak for Data, a cluster administrator must set up the cluster for OpenPages.
- Permissions you need for this task
- You must be an administrator of the OpenShift® cluster.
Before you begin
Ensure that the cluster meets the minimum requirements for installing OpenPages. For details, see System requirements.
Additionally, ensure that a cluster administrator completed the required Pre-installation tasks for your environment. Specifically, verify that a cluster administrator completed the following tasks:
- Cloud Pak for Data is installed. For details, see Installing Cloud Pak for Data.
- The project where you plan to install OpenPages exists.
- For environments that use a private container registry, such as air-gapped environments, the OpenPages software images are mirrored to the private container registry. For details, see Mirroring images to your container registry.
- The cluster is configured to pull the OpenPages software images. For details, see Configuring your cluster to pull images.
- The OpenPages operator subscription exists. For details, see Creating operator subscriptions.
If these tasks are not complete, the OpenPages installation will fail.
Complete the following tasks to install OpenPages:
Setting up the cluster
- If you want to use a tethered project (namespace) for OpenPages instances, set up a tethered project in
IBM Cloud Pak for Data. Note: If you are using a tethered project, you must use an external database. For more information, see Using an external database with OpenPages.
- Set up the storage classes for the database and for the OpenPages application. For more information, Certified storage options for OpenPages.
You can use storage classes in the following combinations:
- Option 1
- You can use OpenShift Container Storage (OCS). With this
configuration, use OCS block storage for the Database data storage class and
use OCS file system storage for all other settings:
- Option 2
- You can use Portworx:
- Option 3
- You can use NFS storage for all storage class settings.
- If you want to use dedicated nodes for the Db2 database, configure the nodes. For more information, see Setting up dedicated nodes.
- If you use, HAProxy, on the load balancer node, edit the
/etc/haproxy/haproxy.cfg file. In the defaults section, change the values for
30m.Run the following command to restart HAProxy:
sudo systemctl restart haproxy
