Hey @abdheshnayak - I've reviewed your changes - here's some feedback:
Overall Comments:
- Consider implementing more robust error handling instead of using panic() in the Run() function. This would improve the service's reliability and make it easier to diagnose issues in production.
- Ensure proper authentication and authorization mechanisms are in place for accessing Kubernetes API information through this service to maintain security.
Here's what I looked at during the review
- 🟡 General issues: 2 issues found
- 🟡 Security: 1 issue found
- 🟢 Testing: all looks good
- 🟢 Complexity: all looks good
- 🟢 Documentation: all looks good

suggestion: Consider more graceful error handling in main()
Instead of using panic(), consider logging the error and performing a controlled shutdown. This approach is more suitable for a production Kubernetes service.
func main() {
if err := Run(); err != nil {
log.Printf("Error running application: %v", err)
os.Exit(1)
}

suggestion: Avoid logging errors within checkSvcHealth
Consider returning errors from this function instead of logging them here. This allows for better separation of concerns and more flexible error handling at higher levels of the application.
err := checkPodHealth(&pod)
if err != nil {
count++
return fmt.Errorf("pod health check failed: %w", err)
}

🚨 suggestion (security): Validate KubernetesApiProxy value
Consider adding validation for the KubernetesApiProxy value, especially since it's used directly in the rest.Config. This can help prevent security issues and improve reliability.
type Env struct {
HttpPort uint16 `env:"HTTP_PORT" default:"3000"`
KubernetesApiProxy string `env:"KUBERNETES_API_PROXY" validate:"required,url"`
