By doing so, it provides a broad overview of the different components that are currently running, allowing you to gauge the complexity in terms of the number of resources and their types.

This visibility is essential for understanding the state of the cluster and for troubleshooting or planning updates, as it allows developers to see how many workloads and services are actively running. The details returned can help identify potential issues or resource configurations that may need to be addressed.

For example, "kubectl view cluster" and "kubectl info cluster" are not valid commands in Kubernetes and wouldn't yield any information about the cluster's resources. "kubectl describe cluster" is also not a standard command in Kubernetes; typically, "kubectl describe" is used with specific resources like pods or deployments, rather than clusters as a whole. Thus, "kubectl get all" stands out as the most
