This is a trivial volume provisioner that is intended to be used to simulate scheduling of stateful workloads, to enable testing with tools like KWOK. This is based on hostpath-provisioner example of the external-provisioner controller.
Example usage in kwok cluster:
# Create K8s cluster and add worker nodes
export KWOK_WORKDIR=/tmp
export KUBECONFIG=/tmp/kubeconfig.yaml
kwokctl create cluster --wait 1m
kwokctl scale node --replicas 4
# Start noop volume provisioner that immediately binds PVCs
docker run -d --name noop-provisioner \
-v /tmp/clusters/kwok/kubeconfig:/kubeconfig \
-v /tmp/clusters/kwok/pki:/etc/kubernetes/pki \
--network kwok-kwok \
