Build in a snap a Galaxy environment for a training classroom of 20-30 participants to allow high interactivity and shared practical work.

This Ansible playbook has been developed and tested on Debian and Ubuntu systems.

In order to use this playbook, you need:

• git
• ansible >= 2.4

List of roles included in this playbook:

• common place where variables available to all roles are defined.
• ansible-galaxy-os to configure the base operating system useful for running Galaxy.
• ansible-postgresql to setup the PostgreSQL server
• ansible-galaxy to configure the Galaxy server.
• ansible-gx-extras to configure several production services as Nginx, Uwsgi and Supervisor.
• ansible-galaxy-tools for automated installation of tools from a Tool Shed into Galaxy.

A first set of variables, that regulate the playbook execution, are available in group_vars/all:

• g4t_manage_os_setup: (default yes) to execute or not the ansible-galaxy-os role
• g4t_manage_db_setup: (default yes) to execute or not the ansible-postgresql role
• g4t_manage_galaxy: (default yes) to execute or not the ansible-galaxy role
• g4t_manage_extras: (default yes) to execute or not the ansible-gx-extras role
• g4t_manage_tools: (default no) to execute or not the ansible-galaxy-tools role
• g4t_manage_datasets: (default no) to execute or not the ansible-gx-datasets role

All the variables that can be configured to execute this playbook are collected into
roles/common/vars/main.yml .

Apply your modifications there.

Since this repository makes use of submodules, you can pass the --recursive option to git clone and initialize all submodules:

git clone --recursive https://github.com/gmauro/galaxy4training

Clone the repository as described above and then run the playbook:

ansible-playbook -i inventory g4t.yml -e brand='G4T' -e admin_users='[email protected]

Easily prepare a development setup using Docker in this way:

• Clone the repository
  git clone --recursive https://github.com/gmauro/galaxy4training

• Edit the code on your machine

• start a docker container
  docker run -p 8080:80 -v /path/to/galaxy4training:/galaxy4training --rm -ti gmauro/ansible:2.6_ubuntu16.04 /bin/bash

• Start Galaxy deployment on the docker container
  cd galaxy4training && ansible-playbook g4t.yml

• Check the result on your browser at localhost
