b4n 命令

常用示例

说明

b4n is an interactive terminal user interface for managing Kubernetes clusters, written in Rust using the kube-rs and ratatui libraries. It provides a keyboard-driven interface for performing common Kubernetes operations without leaving the terminal. The TUI supports full CRUD operations on Kubernetes resources. Users can list, create, edit, and delete resources through the interactive interface. Additional capabilities include viewing resource events with e, streaming pod and container logs with l, launching interactive shell sessions in containers with s, inspecting resource YAML with y, decoding secrets with x, and configuring port forwarding with f. Navigation uses a command palette accessible via : or >, along with dedicated keys for namespace selection (left arrow) and resource kind selection (right arrow). Resources can be filtered with /, and columns can be sorted with Alt+0-9. Resources are selected with Space and deleted with Ctrl+D after confirmation. Mouse support can be toggled with Ctrl+N. The command palette supports configurable aliases for quick resource access. Default aliases include pp for pods, svc for services, cm for configmaps, ds for daemonsets, ns for namespaces, pvc for persistentvolumeclaims, and sts for statefulsets, among others.
