Shutting down and restarting services

In some situations, when you are not using a service but you plan to use it in the future, you can manually shut the service down to prevent it from using resources. You can restart the service when you need to use it again.

Who needs to complete this task?
You must be either:
  • A cluster administrator
  • An instance administrator
When do you need to complete this task?
When you want to temporarily shutdown a service that you are not using.
Important: You cannot shut down a service when autoscaling is enabled for the service. For more information, see Automatically scaling resources for services.

You can shut down a service temporarily when you are not using it. For example, over holidays or during maintenance, you might shut down a service to conserve CPU and memory resources, and then restart the service when you want to use it again.

Use the method that the service supports to shut down a service. Services use one of the following methods:
  • Running the cpd-cli manage shutdown and cpd-cli manage restart commands. For more information about these commands, see manage shutdown and manage restart in the Command-line reference.
  • Running the oc patch command to update the shutdown parameter in the service custom resource (CR) to manually shut down or restart the service.

The following table shows the services that you can manually shut down and restart.
