Title:

Bug description:
  I would like to run Ubuntu Minimal Cloud Image as the base OS on which
  I run Kubernetes and various other containers, but it requires ipset
  and various kernel modules included in the build. Is there a way to
  have those added by default, or a documented process for me to modify
  the kernel on my Minimal Cloud images?

  I tried to use kube-router as a routing platform for connecting the
  containers between Ubuntu hosts, but this requires ipset.

  The error from kube-router:
  I0921 00:19:45.773157       1 kube-router.go:207] Running /usr/local/bin/kube-router version v0.2.0, built on 2018-09-12T08:03:59-0400, go1.10.3
  Failed to run kube-router: Failed to create network routing controller: Failed to create ipset set on system: ipset v6.34: Kernel error received: set type not supported

  After some digging, it seems I need the following modules at least compiled into the kernel as modules:
  root@deva-controller0:~# cat "/boot/config-`uname -r`" | grep IP_SET
  CONFIG_IP_SET=y
  CONFIG_IP_SET_MAX=256
  # CONFIG_IP_SET_BITMAP_IP is not set
  # CONFIG_IP_SET_BITMAP_IPMAC is not set
  # CONFIG_IP_SET_BITMAP_PORT is not set
  # CONFIG_IP_SET_HASH_IP is not set
  # CONFIG_IP_SET_HASH_IPMARK is not set
  # CONFIG_IP_SET_HASH_IPPORT is not set
  # CONFIG_IP_SET_HASH_IPPORTIP is not set
  # CONFIG_IP_SET_HASH_IPPORTNET is not set
  # CONFIG_IP_SET_HASH_IPMAC is not set
  # CONFIG_IP_SET_HASH_MAC is not set
  # CONFIG_IP_SET_HASH_NETPORTNET is not set
  # CONFIG_IP_SET_HASH_NET is not set
  # CONFIG_IP_SET_HASH_NETNET is not set
  # CONFIG_IP_SET_HASH_NETPORT is not set
  # CONFIG_IP_SET_HASH_NETIFACE is not set
  # CONFIG_IP_SET_LIST_SET is not set

  Ubuntu Release:
  ~# cat /etc/lsb-release 
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=18.04
  DISTRIB_CODENAME=bionic
  DISTRIB_DESCRIPTION="Ubuntu 18.04.1 LTS"

  Any help is greatly appreciated.
