With the latest enhancements in IBM Software Hub 5.2.0, you can now seamlessly scale, shut down, and restart services—bringing greater flexibility and control to service management.
SCALE
Starting with Software Hub version 5.2.0, services that support multiple scaling levels can now be configured directly from the IBM Software Hub UI. This allows users to adjust the scaling configuration for one or more components associated with an instance of Software Hub. Scaling of a service changes the capacity of services by adjusting the memory resource settings, the number of CPUs, and the number of pods that are available. This allows you to optimize performance and resource utilization based on your needs.
To scale a service:
- Navigate to the Software Hub Monitoring page.
- Select Services, then choose the specific service you want to scale.
- In the top-right corner of the service page, click the Actions button.
- Select Scale from the dropdown menu.
- Choose the desired scale level for the service components.
This action will initiate a scale change job, similar to using the cpd-cli manage apply-scale-config command. Once the job completes successfully, the updated scale values will be reflected in the UI.
SHUTDOWN/RESTART
You can now shut down specific components and their dependencies directly from the Software Hub UI. You can temporarily shut down a service during periods of low usage such as holidays or maintenance to conserve CPU and memory. This helps you allocate resources more efficiently and restart the service when needed. The shutdown process ensures that all dependent components are stopped before the selected component is shut down. Services that are required by other services cannot be shut down until all dependent services have been shut down first.
NOTE: Services with Horizontal Pod Autoscaling (HPA) enabled, or those requiring manual steps in the shutdown process, cannot be shut down through the UI.
Similar to the scaling feature, a Shutdown/Restart option is now available in the Actions menu dropdown. Clicking Shutdown opens a confirmation dialog displaying the list of dependencies that will also be shut down. After reviewing the list, click Submit to initiate the shutdown job.
Once the service is in shutdown, You will see a restart option in the action dropdown menu. Clicking on restart will trigger a restart operation for the services and all the dependencies.
Conclusion: With IBM Software Hub 5.2.0, managing service lifecycles is now more intuitive and efficient through built-in scaling, shutdown, and restart capabilities. These enhancements give users greater control and flexibility directly from the UI.
