Nikolay Mahotkin 5c69e7d64c Fixing docker DIB element for setting correct MTU 
* docker0 interface in ubuntu had incorrect MTU value
 * Older docker (< v1.1) automatically infer MTU value based
 on host. But since 1.1 docker doesn't do this. It
 sets MTU value 1500 which causes some network problems
 (especially with SSL/TLS/HTTPS) and apps like
 HTTPdSite and NginXSite couldn't clone the repo.

Closes-Bug: 1608836

Kubernetes Elements

This folders contains necessary DIB elements to build Kubernetes image expected by "Kubernetes Cluster" Murano application.

Prerequisites

  1. Install diskimage-builder
sudo pip install diskimage-builder
  1. Install qemu-uils and kpartx

On Ubuntu, Debian:

sudo apt-get install qemu-utils kpartx

On Centos, Fedora:

sudo yum install qemu-utils kpartx

Image building

To build Debian-based image

sudo ELEMENTS_PATH=${murano_agent_root}/contrib/elements:${murano_apps_root}/Docker/Kubernetes/KubernetesCluster/elements \
    DIB_RELEASE=jessie DIB_CLOUD_INIT_DATASOURCES="Ec2, ConfigDrive, OpenStack" disk-image-create vm debian murano-agent-debian \
    docker kubernetes -o debian8-x64-kubernetes

To build Ubuntu-based image

sudo ELEMENTS_PATH=${murano_agent_root}/contrib/elements:${murano_apps_root}/Docker/Kubernetes/KubernetesCluster/elements disk-image-create \
    vm ubuntu murano-agent docker kubernetes -o ubuntu14.04-x64-kubernetes

Where ${murano_agent_root} is a path to murano-agent files and ${murano_apps_root} is a path to murano-apps files.

Please be careful that diskimage-builder uses tmpfs if 8 Gb memory or bigger is detected. In case of 8 Gb tmpfs size is not enough to build kubernetes. Use DIB_NO_TMPFS=1 in this case or hack diskimage-builder.
