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

  2. Switch to the cloned repository

    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

    oc apply -f manifests/serviceaccount.yaml

  5. Create BuildConfig for building the Image inside Openshift

    oc apply -f manifests/buildconfig.yaml

  6. Run the build to create the image

    oc project node-port-controller
oc start-build node-port-controller-build --from-dir . --follow

  7. Create the deployment
