PWX-35917 Adding k8s resources retriever binary and job

[camartinez04]

Portworx Kubernetes resources retriever

This is a simple Kubernetes client written in Go. It interacts with the Kubernetes API to retrieve information about Kubernetes resources like Deployments, Pods, and Services in a specific namespace.

Prerequisites

• Go 1.21

• Kubernetes

• Client-go

Description

The client can run either inside a Kubernetes cluster or outside of it. When running outside, it uses a kubeconfig file for authentication. When running inside a cluster, it uses the service account token provided by Kubernetes.

The client retrieves the list of Deployments, Pods, and Services, and saves them to individual YAML files.

How to use

This tool retrieves Kubernetes objects and Portworx volume information.

Flags:
  -kubeconfig string
    	Path to the kubeconfig file. Specifies the path to the kubeconfig file to use for connection to the Kubernetes cluster.
  -namespace string
    	Portworx namespace. Specifies the Kubernetes namespace in which Portworx is running. (default "portworx")
  -output_dir string
    	Output directory path. Specifies the directory where output files will be stored. (default "/var/cores/px-k8s-retriever")

Examples:
  ./retriever --namespace portworx --kubeconfig /path/to/kubeconfig --output_dir /var/cores
  ./retriever --namespace kube-system --output_dir /tmp

Please specify --namespace, --kubeconfig (if connecting outside the cluster), and --output_dir when running the tool.
