Limit range operations

Creating a limit range

Shown here is an example procedure to follow for creating a limit range.

Procedure

  1. Create the object:

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

View the limit

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 by performing the following steps:

Procedure

  1. Get the list of limit range objects that are defined in the project. For example, a project called demoproject:

    $ oc get limits -n demoproject
    Example Output
    NAME              AGE
resource-limits   6d

  2. Describe the limit range. For example, for a limit range called resource-limits:

    $ oc describe limits resource-limits -n demoproject
    Example Output
    Name:                           resource-limits
Namespace:                      demoproject
Type                            Resource                Min     Max     Default Request Default Limit   Max Limit/Request Ratio
