Limit range operations

You can create, view, and delete limit ranges in a project.

You can view any limit ranges that are defined in a project by navigating in the web console to the Quota page for the project. You can also use the CLI to view limit range details.

Procedure

  • To create the object, enter the following command:

    $ oc create -f <limit_range_file> -n <project>

  • To view the list of limit range objects that exist in a project, enter the following command:

    Example command with a project called demoproject
    $ oc get limits -n demoproject
    Example output
    NAME              AGE
resource-limits   6d

  • To describe a limit range, enter the following command:

    Example command with a limit range called resource-limits
    $ oc describe limits resource-limits -n demoproject
    Example output
    Name:                           resource-limits
Namespace:                      demoproject
