Node Port Controller

This controller allows to access NodePort Services running inside CodeReady Containers from the host when in vsock network mode.

The controller listens to change events on services inside the cluster and exposes/unexposes the ports utilizing the gvisor-tap-vsock (see: https://github.com/containers/gvisor-tap-vsock/) API.

Prerequisites

1. Running CRC Cluster. See: https://github.com/crc-org/crc
2. oc command line tool. See: https://docs.openshift.com/container-platform/4.8/cli_reference/openshift_cli/getting-started-cli.html

Usage

1. Clone the repository

   git clone https://github.com/raynay-r/crc-node-port-controller.git

   cd node-port-controller

3. Create the Openshift project where the controller will run

   oc apply -f manifests/project.yaml

4. Create ServiceAccount with appropriate rights which will be used to run the controller
