building custom image files for docker based provisioning

Introduction

This project describes the process on how to create a base image that can be used for the Docker Based Provisioning project. Unlike other script based provisioning approaches, docker based provisioning will provision a kubernetes cluster by creating and launching only docker containers.

Prerequisities

The prerequisites for the docker based provisioning are:

  • Docker
  • Configuration of Docker called Docker Bootstrap.
    • This particular configuration uses two docker daemons that are run in place of a typical, single daemon setup. The additional docker bootstrap daemon run etcd and flannel as docker containers, which in turn provide the network interface for the main docker daemon.

Supported formats

Currently supported OS:

Currently supported image type: can easily be extended to other operating systems and image types

Kubernetes cluster with main and bootstrap docker daemons
