Kubernetes Go-Client: Retrieving Pod Details

In Kubernetes, the ability to inspect pod details is crucial for effectively managing cluster resources. Using the Kubernetes client-go, it's possible to programmatically access pod information similar to the output of kubectl get pods.

To achieve this, the following steps can be taken:

1. Create a Kubernetes Client:
   Use the meshkitkube library to create a Kubernetes client that connects to your cluster.

client := meshkitkube.NewClient()

2. Instantiate the Pod Interface for a Namespace:

   podInterface := client.KubeClient.CoreV1().Pods(namespace)

3. List All Pods in the Namespace:

   podList, err := podInterface.List(context.TODO(), v1.ListOptions{})

4. Iterate Through Pod Information:
   Loop through the items in the podList and extract the desired details:

• Name: pod.GetName()
• Status: fmt.Sprintf("%v", pod.Status.Phase)
• Ready Pods: Count containers marked as Ready
• Total Containers: Total containers in the pod
• Restarts: Track the count of restarts for each container
• Age: Calculate the time since pod creation

5. Create a Custom Table:
   Assemble the collected information into a table for optimized display.

Using this approach, you can retrieve pod details programmatically, providing valuable insights for monitoring and troubleshooting your Kubernetes environment.
