Customize the container deployment

This section describes how to customize the HCL WebSphere Portal 9.5 container deployment. Follow this procedure to deploy or update the HCL WebSphere Portal deployment.

DX 9.5 containerization is focused on deployment and it uses an operator-based deployment. Goals

• To introduce a supported containerized deployment that HCL WebSphere Portal can continually extend to provide customers with the best possible experience.

• To provide a high level of customization in the deployment and continue to expand on that, along with increased automation.

Customers need to follow the recommended deployment model to ensure the availability of future functions and prevent potential conflicts. Customize the deployment requires updating the deploy/crds/git.cwp.pnp-hcl.com_v1_dxdeployment_cr.yaml file located in the hcl-dx-cloud-scripts/deploy/crds directory in the HCL Digital Experience 9.5 platform packages deployed.

Reference the HCL WebSphere Portal Deployment topic for the list of supported platforms and latest HCL DX 9.5 container package list files that can be downloaded from the HCL WebSphere Portal entitlements on the HCL Software License Portal. Once modified, the deployDx.sh or the updateDx.sh scripts should be run to perform (or update) the target deployment.

Note: All modifications should be made to the custom resource instance and not the individual parts of the deployment.

1. Create a backup of the git_v1_dxdeployment_cr.yaml file.
2. Open the original file in edit mode.

3. Find the line with the text labeled, # Add fields here. Customizations should be done below this line.
4. Add the following customizations as applicable:
   • Volume Size

     By default, the volume size is 100 GB . This can be modified by changing the following:

     

     Note: The volume name and storageClassName should not be modified here.

   • Resources

     By default, the resource requests are set at 2 CPU and 7G RAM. These values can be changed. HCL recommends to adjust the server heap size before changing these values.

     

     Note: Limits are not enforced in the initial 9.5 release.

   • HCL DX 9.5 Container Update CF_171 and higher
     • Limits are enforced.

     • Auto-scaling based on average CPU and memory utilization can be configured.

       Auto-scaling

       When using a Horizontal Pod Autoscale Service, by design, scaling up the amount of HCL DX 9.5 pods is done one at a time. HCL DX 9.5 processes will initiate the requested single instance at a given time until the instance starting is started, to manage scaling in a controlled manager from 1 to N minimum pods set.

       Each deployment takes approximately ~3 to 4 minutes to start, operating on typical hardware environments. Pod instance terminations are also managed with these control practices.Scaling is controlled in the configuration map with these settings, which can be configured. In this example, 5 is the maximum number of DX 9.5 Container pods requested:

       dx.deploy.dxcore.resources.scale.maxreplicas: '5'

       dx.deploy.dxcore.resources.scale.minreplicas: '1'

       

   • Routes/Ingress

     By default in 9.5, base routes are created for the deployment.

     HCL DX 9.5 Container Update CF_171 and higher allows a customer to configure the available routes.We can enable or disable any route and change the name of the secret to be used in the TLS context. The Configuration Wizard is still impacted by the number of running instances.

     

   • Probes

     The default readiness and liveness probes run against the ../ibm/console. This can and should be overridden.

     

     Notes: There are two types of checks:
     • command runs a command against the server
     • http hits either an http or an https URL. The syntax and required fields are shown in the above image.
     • Logging

       By default, logging is done on the shared profile so all instances are writing to a single set of logs, with the volume set for each instance at 1G . For diagnosing production issues this is not ideal. This option allows each instance to write the log to its own log directory.

       

       Notes:

       • The environment must have a self-provisioning storage class provisioner.

       • Enabled must be set to true .

       • Adjusting the log settings must be done to prevent running out of disk storage.

     • Ports

       By default, the deployment uses the default DX ports. The routes in these ports expose Portal through http and https .

       

       Note: If there is a need to configure the containerized Portal to use different ports, the defaults can be overwritten.

5. Once modified, the deployDx.sh and the updateDx.sh scripts should be run to create (or update) the target deployment.
