- Now users can get object info like:

  ```bash
    a. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0:3].name
    b. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[-2:].name
  ```

  Action required for custom scheduler plugin developers:
  Plugins **have to** implement a QueueingHint for Pod/Update event if the rejection from them could be resolved by updating unscheduled Pods themselves.
  Example: suppose you develop a custom plugin that denies Pods that have a `schedulable=false` label.

type minioCollector struct {
	desc *prometheus.Desc
}

// Describe sends the super-set of all possible descriptors of metrics
func (c *minioCollector) Describe(ch chan<- *prometheus.Desc) {
	ch <- c.desc

# TF_LoadLibrary/tf.load_op_library) register their ops and kernels with this

os.Hostname() will be used, in that order. ([#56812](https://github.com/kubernetes/kubernetes/pull/56812), [@dims](https://github.com/dims))

* Custom resources can be listed with a set of grouped resources (category) by specifying the categories in the [CustomResourceDefinition spec](https://kubernetes.io/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/#categories). Example: They can be used with `kubectl get important`, where `important` is a category. ([#59561](https://...

This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file { #the-config-file }

Coming from the previous example, your `config.py` file could look like:

{* ../../docs_src/settings/app02/config.py hl[10] *}
