Kubefwd FAQs

Question 1

Can I use Kubefwd to forward services from multiple Kubernetes namespaces simultaneously?

Accepted Answer

Yes, Kubefwd supports forwarding services from multiple Kubernetes namespaces concurrently. You can specify multiple namespaces using the `-n` flag in the command, for example: `sudo -E kubefwd svc -n default,staging --tui`.

Question 2

What is Kubefwd and what problem does it solve?

Accepted Answer

Kubefwd is a command-line utility that bulk port forwards Kubernetes services to your local machine. It solves the challenge of local development by allowing your applications to access in-cluster services (databases, APIs, caches) by their service names, just as they would in the cluster, eliminating environment-specific configurations.

Question 3

How is Kubefwd different from 'kubectl port-forward'?

Accepted Answer

Kubefwd significantly enhances local development over 'kubectl port-forward' by forwarding all services in a namespace, assigning a unique 127.x.x.x loopback IP to each service to prevent port conflicts, automatically resolving service names via `/etc/hosts`, and featuring auto-reconnect for dropped connections or pod restarts. It also includes an interactive TUI for monitoring.

Question 4

Why does Kubefwd require root or sudo access?

Accepted Answer

Root or sudo access is necessary because Kubefwd modifies the `/etc/hosts` file to enable service name resolution (e.g., `http://api-service:8080`) and manages network interfaces to assign unique 127.x.x.x loopback IP addresses for each forwarded Kubernetes service.

Question 5

What are the core features of Kubefwd?

Accepted Answer

Key features include an interactive TUI with real-time service monitoring and traffic metrics, unique loopback IPs for each forwarded service, automatic reconnection, bulk forwarding of all services in a namespace, and integration with AI assistants via MCP (Machine Coded Prompts) support.
