kubefwd is a command line utility built to port forward some or all pods within a Kubernetes namespace. kubefwd uses the same port exposed by the service and forwards it from a loopback IP address on your local workstation. kubefwd temporally adds domain entries to your /etc/hosts file with the service names it forwards.

When working on our local workstation, my team and I often build applications that access services by their service names and ports within a Kubernetes namespace. kubefwd allows us to develop locally with services available as they would be in the cluster.

kubefwd assumes you have kubectl installed and configured with access to a Kubernetes cluster. kubefwd uses the kubectl current context.

Ensure you have a context by running:

kubectl config current-context

If you are running MacOS and use homebrew you can install kubefwd directly from the txn2 tap:

brew install txn2/tap/kubefwd

To upgrade:

brew upgrade kubefwd

Check out the releases section on Github for alternative binaries or Fork kubefwd and build your own version. I welcome any useful pull requests.
