b4n is a terminal user interface for the Kubernetes API, created mainly for learning the Rust programming language. It is heavily based on the k9s project.
The Cascadia Code font, or any other font with Nerd Font symbols, is required for proper display of the user interface in the terminal.
As the project is in its early stages, the following features are currently supported:
- View a list of Kubernetes resources.
- Delete selected resources.
- Display the YAML configuration of the highlighted resource.
- View logs for the highlighted container.
- Open a shell session in the highlighted container.
- Enable port forwarding for the highlighted container.
The following features are planned for future development:
- Search within YAML configurations and logs.
- View combined logs for all containers in a pod.
- Edit Kubernetes resources (YAML).
- Describe Kubernetes resources.
