Custom Resource Client Example

This example demonstrates how to use the C# Kubernetes Client library to create, get and list custom resources.

Pre-requisits

Make sure your have added the library package

dotnet add package KubernetesClient

Create Custom Resource Definition (CRD)

Make sure the CRD is created, in order to create an instance of it after.

kubectl create -f ./config/crd.yaml

You can test that the CRD is successfully added, by creating an instance of it using kubectl:

kubectl create -f ./config/yaml-cr-instance.yaml

kubectl get customresources.csharp.com

Execute the code

The client uses the BuildConfigFromConfigFile() function. If the KUBECONFIG environment variable is set, then that path to the k8s config file will be used.

dotnet run

Expected output:

strating main()...
working with CRD: customresources.csharp.com
creating CR cr-instance-london
CR list:
- CR Item 0 = cr-instance-london
- CR Item 1 = cr-instance-paris
fetchedCR = cr-instance-london (Labels: {identifier : city, newKey : newValue}), Spec: London
Deleted the CR

Under the hood
