4. ... BUT WHAT IF
there are more servers
change log for every one
I want to setup development environment
manually go through the changelog
and probably do mistakes
the changelog has some blank places
usually it is not that detailed
Holy crap... now what?
7. ALTERNATIVES
Of course there are many:
Puppet
CFEngine
Capistrano
Fabric
glu
...
There is a difference between infrastructure management and
deployment management.
9. CHEF
Solo
for local/one node
no central repository of configuration
Server
installed internally or bought from Opscode
central repository of cookbooks
easy to install on supported OS
Ubuntu
13. COOKBOOKS
managed by Knife
source code stored in Git repository
uploaded to the Chef Server
downloaded by Chef Client on a particular Node
14. HOW TO START COOKING?
You do not need to know Ruby up-front
=
wheew for Javist ;)
but
http://docs.opscode.com/just_enough_ruby_for_chef.html
15. NEXT
Install Chef Workstation if it does not exist
Set up Git repo ( BB | GitHub | ... )
git clone git://github.com/opscode/chef-repo.git
Follow the guide precisely
Note: I keep separate user for development and separate for
deployment
16. WRITE FIRST COOKBOOK
It is simple

you get along with 90% of what is already there for most recipes
you are fine with basic programming techniques

21. NOTABLE HINTS
(re)create, not update
rather don’t update file, find a way how to create it at once
more detailed steps then you expected
if you thought there are 10 steps what to execute in such an
automated way in your head, there are 60 at least
cookbook wrapper pattern
describe the possibility to override resources in the
“cookbook wrapper”
