@Marvin in this code snippet, what is plural and what is group? would you give me an example?

from prefect import flow
from prefect_kubernetes.credentials import KubernetesCredentials
from prefect_kubernetes.custom_objects import get_namespaced_custom_object

@flow
def kubernetes_orchestrator():
    custom_object_metadata = get_namespaced_custom_object(
        kubernetes_credentials=KubernetesCredentials.load("k8s-creds"),
        group="crd-group",
        version="crd-version",
        plural="crd-plural",
        name="my-custom-object",
    )

In the code snippet you provided, we're looking at part of an orchestration script written with Prefect, which interfaces with Kubernetes. `plural`: This refers to the plural form of the

kind

of the Kubernetes Custom Resource Definition (CRD). For example, if the

kind

is

Pod

, the

plural

might be

pods

. `group`: This is the name of the API group that the Custom Resource Definition (CRD) belongs to. Kubernetes supports multiple API groups to extend its functionality, and CRDs can be a part of custom groups. As for an example, suppose you have a Kubernetes cluster with a custom resource of kind

MyCustomResource

and you have defined a CRD for it. Let's also assume your CRD is within the group

<http://example.com|example.com>

and the version is

v1alpha1

. The

plural

might be defined as

mycustomresources

because you typically access multiple instances of the resource at a time. Your Python code would look something like this:

python
from prefect import flow
from prefect_kubernetes.credentials import KubernetesCredentials
from prefect_kubernetes.custom_objects import get_namespaced_custom_object

@flow
def kubernetes_orchestrator():
    custom_object_metadata = get_namespaced_custom_object(
        kubernetes_credentials=KubernetesCredentials.load("k8s-creds"),
        group="<http://example.com|example.com>",
        version="v1alpha1",
        plural="mycustomresources",
        name="my-custom-object-name",
    )

Here,

mycustomresources

is the

plural

indicating how you refer to the resources in API calls, and

<http://example.com|example.com>

is the

group

specifying the grouping under the Kubernetes API groups.

my-custom-object-name

is the specific name of the custom object instance you want to retrieve.
