Installation

Prerequisites

Currently Kayobe supports the following Operating Systems on the control host:

  • CentOS 7.3
  • Ubuntu 16.04

To avoid conflicts with python packages installed by the system package manager it is recommended to install Kayobe in a virtualenv. Ensure that the virtualenv python module is available on the control host. It is necessary to install the GCC compiler chain in order to build the extensions of some of kayobe’s python dependencies. Finally, for cloning and working with the kayobe source code repository, Git is required.

On CentOS:

$ yum install -y python-devel python-virtualenv gcc git

On Ubuntu:

$ apt install -y python-dev python-virtualenv gcc git

Installation

This guide will describe how to install Kayobe from source in a virtualenv.

The directory structure for a kayobe control host environment is configurable, but the following is recommended, where <base_path> is the path to a top level directory:

<base_path>/
    src/
        kayobe/
        kayobe-config/
        kolla-ansible/
    venvs/
        kayobe/
        kolla-ansible/

First, change to the top level directory, and make the directories for source code repositories and python virtual environments:

$ cd <base_path>
$ mkdir -p src venvs

Next, obtain the Kayobe source code. For example:

$ cd <base_path>/src
$ git clone https://github.com/stackhpc/kayobe

Create a virtualenv for Kayobe:

$ virtualenv <base_path>/venvs/kayobe

Activate the virtualenv and update pip:

$ source <base_path>/venvs/kayobe/bin/activate
(kayobe) $ pip install -U pip

Install Kayobe and its dependencies using the source code checkout:

(kayobe) $ cd <base_path>/src/kayobe
(kayobe) $ pip install .

Finally, deactivate the virtualenv:

(kayobe) $ deactivate

Creation of a kayobe-config source code repository will be covered in the configuration guide. The kolla-ansible source code checkout and python virtual environment will be created automatically by kayobe.
