The Platform CLI checks whether the
br_netfilter
module is loaded and exits if
it is not available. This module is required to enable
transparent masquerading and to facilitate Virtual Extensible
LAN (VxLAN) traffic for communication between Kubernetes pods
across the cluster. If you need to check whether it is loaded,
run:
$ sudo lsmod|grep br_netfilter
br_netfilter 24576 0
bridge 155648 2 br_netfilter,ebtable_broute
If you see the output similar to shown, the
br_netfilter
module is loaded. Kernel
modules are usually loaded as they are needed, and it is
unlikely that you need to load this module manually. If
necessary, you can load the module manually and add it as a
permanent module by running:
$sudo modprobe br_netfilter
$sudo sh -c 'echo "br_netfilter" > /etc/modules-load.d/br_netfilter.conf'
