Kubectl
Kubectl is the command-line interface (CLI) tool for interacting with Kubernetes clusters, allowing users to deploy, inspect, manage, and troubleshoot applications and resources. It serves as the primary way to control Kubernetes objects like pods, services, and deployments through a set of commands. This tool is essential for developers and operators working in containerized environments orchestrated by Kubernetes.
Developers should learn Kubectl when working with Kubernetes to efficiently manage containerized applications, automate deployments, and debug issues in cloud-native environments. It is crucial for use cases such as scaling applications, updating configurations, and monitoring cluster health, especially in DevOps and microservices architectures where Kubernetes is widely adopted.
