Usage

Here is an example playbook that uses these roles (plus a few extra internal-to-dce roles) to build a single box running all the Samvera components:

- hosts: '{{ host }}'
  name: ensure python is installed for ansible
  user: ubuntu
  gather_facts: false
  pre_tasks:
      - name: update apt-get
        raw: sudo apt-get update
      - name: install python for ansible
        raw: sudo apt-get -y install python-simplejson

- hosts: '{{ host }}'
  name: configure server
  user: ubuntu
  gather_facts: true
  vars:

An observation for minimal test installs: these packages install successfully on an AWS ubuntu server with 4 gigabytes of RAM (t3a.medium), but not on one with 1 gigabyte of RAM (a free tier "micro" server).
