Ansible based deployment system of Django

How to use:

• Add id_rsa.pub key to a node(s) into /root/.ssh/authorized_keys to have root access via ssh from your local machine
• Adjust settings in hosts and group_vars/* configs if needed
• Initially you will need a database dump in /files/db/prod_init.pgsql created by: pg_dump --no-password --format=c -U {{ db_user }} {{ db_name }} > prod_init.pgsql Further dev and preprod will search dumps in /backup/day/{{ production_db_name }}.pgsql
• Run ansible-playbook deploy_dev.yml from the directory that contains ansible.cfg to deploy site.dev
• Run ansible-playbook deploy_preprod.yml to deploy preprod-site.dev
• Run ansible-playbook deploy_prod.yml to deploy prod-site.dev or site.com
