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.

Tested directly on macOS and linux based docker containers.

kubefwd assumes you have kubectl installed and configured with access to a Kubernetes cluster. kubefwd uses the kubectl current context. The kubectl configuration is not used, however it's configuration is needed to access a Kubernetes cluster.

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.
