update_source.yml

# Ansible playbook for updating a source-installed CKAN site
#
# Generally used to update beta.ckan.org and master.ckan.org on the staging
# server (currently s084), but it can be easily adapted to your own deployment
# needs.
#
# Add the staging server IP tp your /etc/ansible/hosts file (check if the IP
# is up to date):
#
#   [staging]
#   50.56.81.219
#
# Install ansible and run this playbook:
#   
#   ansible-playbook update_source.yml -u amercader -s
#
# If no variables are passed, the site "master" is updated with the latest
# "master" branch. To update another CKAN site and/or version pass the 
# following variables:
#
#   ansible-playbook update_source.yml -u amercader -s --extra-vars="site=beta version=release-v2.1"
#
