# Usage ./hack/bump-kind.sh <provider> <kind_version> <k8s version>
# If no parameters beside provider, are used, it will take latest kind version,
# with k8s version according latest kubevirtci vm based provider.
# If only kind_version is used, it will take k8s version according latest kubevirtci vm based provider
# examples: ./hack/bump-kind.sh kind-sriov v0.19.0
#           ./hack/bump-kind.sh kind-sriov v0.19.0 1.28
