Evolution of Darwin (EoD) Configuration

This project contains Ansible playbooks and configuration of infrastructure on an existing OpenStack cloud for the Cambridge UIS Evolution of Darwin (EoD) system. This includes:

  • A demo project and user accounts in OpenStack keystone.
  • Compute node flavors in OpenStack nova for the various compute and storage node types.
  • Networks, subnets and routers in OpenStack neutron for the external ilab and internal networks.

Preparation

Ensure that Ansible is installed, either via the system package manager or pip. If required, use a virtualenv to avoid interference with the system python packages. For example:

$ virtualenv venv
$ source venv/bin/activate
$ pip install -U pip
$ pip install -r requirements.txt

Install Ansible role dependencies from Ansible Galaxy:

$ ansible-galaxy install \
    -p ansible/roles \
    -r requirements.yml

Usage

First, ensure that OpenStack authentication environment variables are set, typically by sourcing an OpenStack environment file.

To configure OpenStack infrastructure:

$ tools/eod-config

To run a specific playbook:

$ tools/eod-config -p </path/to/playbook>

To specify additional arguments to ansible-playbook, separate them with a double hyphen (--):

$ tools/eod-config -- <arguments>

For example, a vault secret stored as a file can be passed as an extra configuration parameter:

$ tools/eod-config -- --vault-password-file config-secret.vault
