Headlamp vs Kubernetes

Headlamp is a free graphical interface for managing Kubernetes clusters, available as a browser-based application and a desktop app. It adjusts its controls to Kubernetes role-based permissions, so users see only actions their role allows. Users can monitor multiple clusters and switch between them in the interface. A plugin system extends core functionality for specific workflows, with integrations including Backstage, Flux, Inspektor Gadget, Kompose, Kubescape, KubeVirt, OpenCost, Prometheus, and Trivy. Headlamp can be deployed in a Kubernetes cluster using Helm or YAML configuration. Documented sign-in methods include client certificates, bearer tokens, and OIDC. The project says a user token may be stored in browser local storage, but not in its backend or server. Its plugin guidance warns that plugins share the main application’s JavaScript context and recommends installing only trusted plugins. Headlamp is available at no charge under Apache 2.0. The project says it tests its desktop app on Windows, macOS, and Linux. Support options include documentation, community Slack, GitHub issues, and monthly community meetings.

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It supports stateless, stateful, and data-processing workloads, and can run locally, in a cloud, or in a datacenter; users can also choose a managed service rather than operate a cluster themselves. It coordinates gradual updates while monitoring application health and can roll back a change if something goes wrong. Pods receive IP addresses and groups of Pods can share a DNS name, with load balancing across them. Kubernetes can mount storage from local, public-cloud, or network systems such as iSCSI or NFS. Secrets and configuration can be updated without rebuilding images. Scaling can be manual or automatic based on CPU use. Security mechanisms include Secrets, Pod security standards, RuntimeClasses, network policies, admission controllers, and audit logging. Kubernetes is free, with a listed plan price of free. It does not include application-level services such as databases, message buses, caches, or cluster storage systems.
