Kubernetes tools are software applications designed to help manage and orchestrate containerized applications within a Kubernetes cluster. These tools simplify tasks such as deployment, scaling, and monitoring, making it easier for developers and operators to maintain their applications. Popular tools include kubectl, the command-line interface for interacting with Kubernetes, and Helm, a package manager that streamlines the installation of applications. In addition to these, there are tools like Prometheus for monitoring and alerting, and Istio for managing service mesh and traffic. These tools enhance the functionality of Kubernetes, providing essential features for managing complex applications in a cloud-native environment.
