Edward Tan gave a great presentation (slides in vim!) on using puppet on FreeBSD. He introduced FreeBSD and showed us how puppet interacts with the system.

* How many of you heard about FreeBSD?
* How many admins here?
* BSD?
* Linux?
* Other unix?
* windows???
:p gotta ask

5. What are you doing?
* Full time System Administrator
* network related
* DNS
* Radius
* Apache
* LDAP
* Cacti
* Nagios
* -- snip --
(the list is getting too long)
* shells
* perl
* bourne & again shell
* Rest of the time
* FreeBSD

6. FreeBSD? What's that?
* Unix variant
* started from 386BSD, 1993
* advance, complex, sophisticated
* OS comes with :
* ZFS
* PF (packet filter)
* 10gbps
* IPv6 ready (since y2k)
* use by :
* companies
Apple
Cisco
Juniper
* web
Yahoo!
Apache
Netcraft
(... next)

7. * a true operating system
* not just a kernel, but a base comes with it of tools & programs
* ports
* flexibility of source code
* simplicity of package management tools
* more then 23,000 applications waiting to be install by mere :
"make install"
(... next)
7/25

8. * and yet simple directory structured
* / root
* /dev device nodes
* /boot bootstrap needed programs & files
* /etc configurations
* /usr user land utilities & apps
* /usr/ports The FreeBSD ports collection
* /usr/local local executables & libraries
* /usr/local/share/doc documentations aka doc
* /var variable files
* /bin user utilities & apps
* /sbin system utilities & apps
* /mnt directory for mount points
* /tmp temporary directory
* these clearly defined directories eases organization of information
on the disk

9. Linus Torvalds once said :
"If 386BSD had been available when I started on Linux,
Linux would probably never had happened."

10. Okay, why is there anything to do with Puppet?
* I'm taking care of more then 60 servers
* 80% of it is FreeBSD
* new deployment & migration of these servers are happening
* new projects needs new services
* hardware refreshment & virtulization is moving these servers around
* disaster recovery
* automated
* redundancy
* automated setup of new server requires minimum documentation
* policies can be applied automatically
* ntpd
* sshd
* sudoers
* resolv.conf
* syslogd
* etc

11. Wow, you need to manage your configs more efficiently.
* Some alternative
* svn
* still required certain amount of work after svn export
* OS integration is minimum
* e.g.
create user
configure network card
static
* doesn't do templating & file line editing
* e.g. file_line in stdlib
(... next)
11/25

12. * cssh
* cool
* reduced repetitious work across servers when deployment
* but still back to square one when customizing servers
(... next)

13. * Bcfg2/etch
* never like HTML
(... next)
13/25

14. * Chef
* wolf in disguise
* not free, at least for modules
(... next)
14/25

15. * cfEngine
* looks promising
* puppet just sound better
(... next)
15/25

16. Why Puppet?
* excellent documentation
* step by step guide
* tutorial with Virtual Machine provided
* surprisingly easy DSL
* client server model
* manages other platform also
* linux
* windows
* cisco?
* it works with FreeBSD
* system
* ports installation
* user creation
* service start/stop/restart
* file system
* file creation
* ownership
* available through ports
* cd /usr/ports/sysutils/puppet; make install
(... next)
16/25

17. But I thought you mention Lazy, Impatience & Hubris?
* Lazy
* The manifest & modules needs to be setup once and can use many times
* Impatience
* Puppet's excellent DSL & docs give gradual learning curve
* only learn what you need to know and implement
* Hubris
* Manifest & modules are the essence of using (showing off) Puppet

18. How do I install Puppet on FreeBSD?
* use ports
* it requires
* ruby
* portupgrade
* others ...
(... next)
18/25

19. Enough said, can you show me?
* expect these :
* "Puppetless" installation & configuration of FreeBSD
* apache22
* vhost
* test page
* Puppet master FreeBSD installation
* installation Puppet
* dependency installation
* Puppet master configuration
* client installation
* requirement installations
* first sign up of puppet with puppet master
* show off manifest of
* installation of ports
* user environment settings
* bash
* vim
* ssh
* tmux
* sudoers
* apache22
* vhost
* test page

21. * conclusion after demo
* for linux admin, puppet just works
* for freebsd admin, puppet just works
* for freebsd wannatry, puppet just works
(... next)
21/25

22. What I hope to see Puppet in FreeBSD
* portmaster instead of portupgrade
* new & shiny
* patches are active
* simple dependency, /bin/sh only
(... next)

25. Errata
* On slide 14, stating Chef is not Free wasn't true. This was a last minute learning that,
there are open source Chef's modules which can be download and use freely. My mistake.
