cni-plugin-flannel

A CNI network plugin that is powered by flannel

This plugin is designed to work in conjunction with flannel, a network fabric for containers. When flannel daemon is started, it outputs a /run/flannel/subnet.env file that looks like this: FLANNEL_NETWORK=10.1.0.0/16 FLANNEL_SUBNET=10.1.17.1/24 FLANNEL_MTU=1472 FLANNEL_IPMASQ=true This information reflects the attributes of flannel network on the host. The flannel CNI plugin uses this information to configure another CNI plugin, such as bridge plugin.
