The Kubernetes Dashboard provides a web-based user interface for managing and monitoring Kubernetes clusters. It offers several key benefits, including simplified cluster management, real-time monitoring, improved accessibility, and streamlined troubleshooting. The dashboard has various features such as a web-based user interface, overview of applications running, resource management, and authentication and authorization. However, it may lack complex features compared to other web UIs like Lens, Rancher, and Octant. To access the dashboard securely, users can create a secure connection using kubectl proxy and authenticate with a token or kubeconfig file. The Kubernetes Dashboard is suitable for small to medium-sized clusters and teams who want a straightforward solution, but it may not be ideal for large-scale systems or complex use cases. Its extension and customization possibilities are limited compared to other web UIs.
