Dockerfile

#
# This is the OpenShift ovn overlay network image.
# it provides an overlay network using ovs/ovn/ovn-kube
#
# The standard name for this image is ovn-kube

# Notes:
# This is for a development build where the ovn-kubernetes utilities
# are built in this Dockerfile and included in the image (instead of the rpm)
#
# This is based on centos:7
# openvswitch rpms are from
# http://cbs.centos.org/kojifiles/packages/openvswitch/2.9.0/4.el7/x86_64/
#
# So this file will change over time.
