contrib/cni

There are a wide variety of different CNI network configurations. This directory just contains some example configurations that can be used as the basis for your own configurations (distributions should package these files in example directories).

To use these configurations, place them in /etc/cni/net.d (or the directory specified by crio.network.network_dir in your overwrite of /etc/crio/crio.conf.d).

CRI-O will only choose the network that has been specified via crio.network.cni_default_network.

In addition, you need to install the CNI plugins necessary into /opt/cni/bin (or the directories specified by crio.network.plugin_dir). The two plugins necessary for the example CNI configurations are loopback and bridge. Below is a tutorial on downloading and setting up the CNI plugins.

Download the CNI plugins source tree:

git clone https://github.com/containernetworking/plugins
cd plugins
git checkout v0.8.1

Build the CNI plugins:

./build_linux.sh # or build_windows.sh
