demo.txt

Preparation
===========

# preparation - start with clean environment
vagrant destroy chef_server -f
vagrant destroy c12345_svn -f
librarian-chef clean
vagrant up chef_server
vagrant up c12345_svn


Scenario
========

we need a svn server for project c12345 - NOW!


Development Phase
=================

# check out the subversion recipe
git clone git://192.168.90.153/rmu/camp2012-cookbook-subversion.git subversion

# test subversion recipe locally with virtualbox and chef solo 
vagrant up

# take a look at databags, check if it works in browser 
# 	go to http://192.168.33.12/svn/repo1, 
# 	log in with hans 	=> should not work
#	then try /repo2 	=> should work

# modify databags, reload and test again
sublime_text ../../my-chef-repo/data_bags/camp-svn/subversion.json
vagrant provision

# ok, seems to work, no longer need the vm
vagrant destroy -f


Go Live Phase
=============

# edit Cheffile, add dependency to subversion recipe
sublime_text Cheffile

# pull in dependencies
dir cookbooks
librarian-chef install
dir cookbooks

# upload cookbook
knife cookbook upload --all

# oh - where is our server actually?!? 
#	ask IT center for ip / hostname
#	33.33.3.17 / c12345-svn

# check that there is nothing running yet
#	go to http://33.33.3.17/svn/foo 

# set up svn repositories for this host
mkdir data_bags\c12345-svn
sublime_text data_bags/c12345-svn/subversion.json
	{

	  "repos": [

knife data bag from file users users.json

knife bootstrap 33.33.3.17 -x vagrant -P vagrant --sudo -N c12345-svn -r 'recipe[subversion::server]' -d 'ubuntu12.04-gems'

# check if it works
#	go to http://33.33.3.17/svn/foo
#	login with peter/123	=> should work
