Cluster Network Operator

This is an operator that manages the networking components for an openshift cluster.

Building

You can build an image using podman with

./hack/build-image.sh

You might need sudo:

BUILDCMD="sudo podman build" ./hack/build-image.sh

Or you could use a docker that supports multi-stage builds

BUILDCMD="docker build" ./hack/build-image.sh

Running

There are some premade Kubernetes manifests to run a development build. After setting the image URL to something sane in the daemonset, do:

oc create -f manifests/
oc create -f sample-config.yaml

Then you can watch the daemonset with kubectl -n openshift-cluster-network-operator logs <PODID>.
