Expert Mode

If the preceding typical Volcano scheduling configurations cannot meet your needs, use the expert mode to customize scheduling policies.

volcano-scheduler is the component responsible for pod scheduling. It consists of a series of actions and plugins. Actions should be executed in every step. Plugins provide the action algorithm details in different scenarios.

You can customize scheduling policies based on the description of each action and plugin in the official documentation.

For details, see Volcano Scheduler.
